Asus ROG Zephyrus G15 review
Frame rates
1920×1080, High preset, upscaling off.

Not scored: incomplete benchmark suite
Every scored laptop on this site is averaged over the same 5 games, and this one is short of Cyberpunk 2077, Baldur's Gate 3. A mean over 3 games is not comparable to a mean over 5, so we publish the figures we have and leave the score blank rather than rank it against machines tested on a different set. The numbers below are real - the suite is just incomplete.
How these numbers were produced
Frame rates here are not measured by us, and we label how each one was arrived at. A figure marked measured comes from a published run on that exact machine. A figure marked representative is derived from the GPU and its power limit (TGP) and cross-referenced against published reviews - a sound estimate of what that configuration delivers, but not a measurement of that specific laptop. Unless stated otherwise, numbers are 1920x1080, High preset, upscaling off. Where a laptop ships in several power configurations we use the wattage of the exact SKU listed, because a 140W RTX 5070 and a 115W one are not the same product.
In use
The short version
The Asus ROG Zephyrus G15 (GA503Q) is a compactly specified gaming laptop built around an RTX 3080, Ryzen 9 5900HS, 32GB of memory, a 1TB SSD and a 15.6in 2560x1440 IPS display running at 165Hz. The headline hardware remains serious, but the published frame-rate data makes clear that this is not a machine that can simply be assumed to deliver 165fps in every modern game at high settings. Its results range from 198fps in FIFA 21 and Star Wars Squadrons to 70fps in Cyberpunk 2077 1.0, with plenty of demanding games sitting between 74fps and 99fps.
That does not make it a weak performer. Notebookcheck’s figures at 1920x1080, High preset and with upscaling disabled show strong results in a broad selection of games. Doom Eternal reaches 165fps, F1 2020 manages 162fps, The Witcher 3 reaches 155fps and GTA V records 152fps. Competitive and older games are therefore well served, while many major single-player releases remain comfortably above 60fps. The issue is expectation: an RTX 3080 badge can suggest that maximum-refresh gaming is guaranteed, but the data does not support that conclusion in the heavier titles.
The more important qualification is that the fitted screen is a 2560x1440 panel, while the published benchmarks were recorded at 1920x1080. A game that reaches 131fps in Battlefield V at the benchmark setting should not be treated as evidence that it will run at the panel’s native resolution at the same figure. We do not have comparable 2560x1440 results in the supplied data, so it would be wrong to manufacture an estimate. What can be said is that the 1080p numbers offer a strong baseline for deciding where the laptop has headroom and where a user should expect to make settings choices.
The Zephyrus makes most sense for somebody who wants a 1.99kg laptop with high-end components, a 90Wh battery and a sharp 15.6in display, but who understands that the screen’s 165Hz ceiling is an opportunity rather than a promise. It is a good fit for players who mix fast games such as FIFA 21, Star Wars Squadrons, Doom Eternal, F1 2020, Apex Legends and Dota 2 with demanding single-player titles, and who are prepared to tune settings according to the game rather than expecting one preset to suit everything.
It is less convincing for a buyer whose entire priority is extracting the highest possible frame rates from an RTX 3080-class machine. The supplied comparison data shows that this Zephyrus can be tied by an RTX 3060 laptop at 140W and by an RTX 3070 Ti laptop at 150W in the shared games, while a 175W RTX 3080 Ti laptop is substantially quicker. The model’s GPU power limit is not provided in the fact sheet, so there is no sound basis for assigning a wattage to this RTX 3080 or claiming that it has been deliberately restricted to a particular level. But the comparison results do show the practical point: the GPU name alone does not settle performance.
There is no confirmed UK price for this configuration. That is a major omission when judging value. A laptop with these specifications could be compelling at one price and difficult to recommend at another, particularly when the shared-game comparisons show that lower-tier GPU names do not necessarily translate into lower measured frame rates. Without a confirmed UK price, this is a performance-and-portability recommendation, not a value verdict.
Performance
What the published results say
Notebookcheck measured the Asus ROG Zephyrus G15 at 1920x1080 using the High preset, with upscaling disabled. Those conditions matter. They provide a consistent view of conventional rasterised gaming performance without relying on an upscaling mode to raise the result, but they are not native-resolution 2560x1440 results and should not be presented as such.
The highest measured figures are excellent for a 165Hz display. FIFA 21 reaches 198fps, while Star Wars Squadrons also reaches 198fps. Doom Eternal records 165fps exactly, matching the panel’s stated refresh rate. F1 2020 follows closely at 162fps, and The Witcher 3 reaches 155fps. GTA V manages 152fps, while Apex Legends records 144fps. In these games, the benchmark data points to a system that can make meaningful use of a high-refresh display at 1080p High.
There is an important distinction between matching the panel’s refresh rate in a benchmark and guaranteeing a permanently locked refresh-rate experience. The supplied data gives measured figures, not a full account of frame-time consistency, minimum frame rates or performance in every location and gameplay scenario. It is appropriate to say that Doom Eternal’s 165fps measurement meets the screen’s stated refresh rate in the test conditions. It is not appropriate to convert that result into a promise that every moment of every session will remain at 165fps.
The next performance group remains very strong. Gears Tactics records 136fps, Battlefield V manages 131fps and Dota 2 reaches 126fps. Rage 2 follows at 116fps, GRID 2019 at 113fps and Yakuza Like a Dragon at 112fps. Hunt Showdown and Shadow of the Tomb Raider both record 111fps. The Division 2 reaches 105fps, while Far Cry New Dawn is just above that threshold at 101fps. These are not merely acceptable results. At the benchmark settings, they indicate fluid high-refresh play even where the Zephyrus is not reaching the full 165Hz capability of its display.
At this point in the list, the screen’s refresh rate should be interpreted realistically. A result around 100fps will not fill a 165Hz panel in the same way as a result at 165fps, but it is still far above the basic 60fps target commonly associated with smooth gameplay. The benefit of the 165Hz display is not limited to a binary choice between reaching 165fps and failing to do so. The panel gives the machine room to display higher frame rates in games where the hardware can produce them, while still being a high-specification screen for games that sit lower in the benchmark list.
Another substantial group sits around the upper double digits. Mafia Definitive Edition records 99fps, and Star Wars Jedi Fallen Order reaches 98fps. Borderlands 3 and Need for Speed Heat both record 94fps. Serious Sam 4 follows at 93fps. Call of Duty Black Ops Cold War reaches 89fps, Immortals Fenyx Rising records 88fps and Dirt 5 manages 86fps. Metro Exodus and Red Dead Redemption 2 both reach 85fps. Control, Death Stranding and Watch Dogs Legion each record 82fps.
This is the part of the benchmark spread that best explains the Zephyrus G15’s real position. It is powerful enough to run demanding games at well above 60fps under Notebookcheck’s 1080p High conditions, but it does not have an unlimited margin. Metro Exodus at 85fps, Red Dead Redemption 2 at 85fps and Watch Dogs Legion at 82fps are good results. They are not results that support the idea of native-resolution, maximum-refresh gaming without compromise, because they are already below the screen’s refresh rate before moving from 1920x1080 to 2560x1440.
The lowest results are still playable-looking on the evidence available, but they need a different buying mindset. Crysis Remastered records 79fps and Anno 1800 reaches 78fps. Assassin’s Creed Valhalla manages 74fps, while X-Plane 11 records 72fps. Cyberpunk 2077 1.0 is the lowest listed game at 70fps. These figures are not failures, especially with upscaling disabled, but they are a reminder that the panel and the GPU are not perfectly matched for every kind of game at every possible setting.
Cyberpunk 2077 is particularly useful as a caution against reading only the fastest entries. The listed result applies specifically to Cyberpunk 2077 1.0 under the benchmark conditions. It should be read as a result for that named version, not as a claim about every later version, patch, expansion or graphics configuration. The same principle applies generally: these are attributable figures from a dated benchmark source, not a timeless guarantee for future game code.
The benchmark spread is the important story
The frame-rate range from 198fps down to 70fps is wide, and it is more informative than any single headline result. A laptop that posts 198fps in FIFA 21 can clearly feel extremely fast in the right game. That does not erase the 70fps result in Cyberpunk 2077 1.0 or the 74fps figure in Assassin’s Creed Valhalla. Conversely, the demanding titles do not erase the excellent showing in Doom Eternal, F1 2020, GTA V, Apex Legends and Battlefield V. A sensible assessment must hold both parts of the data at once.
At the fast end, FIFA 21, Star Wars Squadrons, Doom Eternal and F1 2020 give the Zephyrus a credible case as a high-refresh machine. GTA V at 152fps and Apex Legends at 144fps strengthen that case. A player spending most of their time in these kinds of games has a clear reason to value the 165Hz panel, even though not every measured result reaches its full refresh rate.
At the middle of the list, games such as Gears Tactics, Battlefield V, Dota 2, Rage 2, GRID 2019, Yakuza Like a Dragon, Hunt Showdown, Shadow of the Tomb Raider, The Division 2 and Far Cry New Dawn show the system operating in a broad high-frame-rate zone. The measured figures between 101fps and 136fps are strong enough to make the Zephyrus feel substantially more capable than a laptop built only to target 60fps. Yet they also illustrate why a 165Hz specification should not be treated as the machine’s universal performance level.
At the demanding end, the laptop’s results point towards a more measured settings strategy. Mafia Definitive Edition, Star Wars Jedi Fallen Order, Borderlands 3, Need for Speed Heat, Serious Sam 4, Call of Duty Black Ops Cold War, Immortals Fenyx Rising, Dirt 5, Metro Exodus, Red Dead Redemption 2, Control, Death Stranding and Watch Dogs Legion all fall below 100fps in the supplied numbers. That does not mean they are unsuitable for the Zephyrus. It means that a buyer who sees a 165Hz QHD screen and expects every demanding game to run near that limit will be disappointed.
For these heavier games, the sensible question is not whether the laptop has enough power to run them at all; Notebookcheck’s figures demonstrate that it does at 1080p High. The question is whether the buyer values native 2560x1440 output, the High preset, a particular frame-rate target, or the use of upscaling where available. The source data intentionally excludes upscaling, so it cannot answer the last of those questions. It also does not provide native-resolution measurements. Anyone buying primarily for the most demanding games should therefore treat the benchmark list as evidence of strong 1080p High performance, not proof of a particular 1440p setting combination.
What can and cannot be said about GPU power
The RTX 3080 name is only one part of the performance story in a gaming laptop. GPU power limits matter in practice because they influence how much performance a given GPU configuration can sustain. However, the Asus GPU power limit is not given in the supplied facts. It would be wrong to state a wattage, to label it low-power or high-power, or to attribute its performance to a particular thermal or electrical setting without evidence.
What the benchmark data does allow is a practical observation. The Zephyrus is not automatically faster than every laptop carrying a lower-numbered GPU. Against the Schenker XMG Core 15 (M22), which has an RTX 3060 at 140W, the shared-game average is level. It is also level against the Schenker XMG Neo 15 with an RTX 3070 Ti at 150W. These are meaningful results because they show why shoppers should compare measured performance rather than buy by GPU label alone.
The MSI Raider GE77 HX provides the other side of that argument. It uses an RTX 3080 Ti at 175W and is ahead by 43fps on average across the shared games. The gap is substantial. It demonstrates that the RTX 3080 Ti name, the stated 175W figure and the Raider’s measured results combine to produce a clearly different performance outcome in this comparison. That does not prove exactly why every part of the difference exists, because the supplied facts do not provide a full platform-by-platform technical breakdown. But it does show that buyers prioritising maximum frame rates should not assume the Zephyrus is equivalent to every ostensibly similar high-end GPU laptop.
The reverse comparison matters too. The Zephyrus is ahead of the MSI Prestige 15 with an RTX 3050 Ti at 105W by 53fps on average across the shared games. That is a decisive measured advantage, not a minor technicality. The Asus belongs in a distinctly higher performance tier than that particular RTX 3050 Ti configuration in the games shared by the two machines.
There is a temptation to turn these comparisons into a simple hierarchy based on wattage. The supplied data does not justify that. The Zephyrus’s own GPU power limit is unconfirmed here, and the comparisons cover shared games rather than an identical complete suite for every machine. The defensible conclusion is narrower and more useful: power specification is relevant, GPU names are not enough, and the actual published frame rates should drive the purchase decision.
The scoring-suite caveat
The supplied scoring-suite entries for the Zephyrus are GTA V at 152fps, Dota 2 at 126fps and X-Plane 11 at 72fps. The mean across those three games is 117fps. That figure is useful as a compact description of those three results, but it is not a complete cross-laptop ranking metric for this machine.
There are no supplied figures for Final Fantasy XV or Strange Brigade. Because comparable ranked results are averaged over the same five games, this incomplete set cannot be ranked fairly against machines with the complete set. That limitation should not be hidden. The individual results remain useful, and the shared-game rival comparisons remain useful, but the Zephyrus should not be placed in a formal overall league table from a partial scoring suite.
The three listed scoring-suite games also demonstrate why averages need context. GTA V at 152fps, Dota 2 at 126fps and X-Plane 11 at 72fps are very different results. Combining them produces a summary, but it does not make X-Plane 11 perform like GTA V, nor does it tell a buyer which of those titles resembles the games they actually play. For a prospective owner, the title-by-title data is more actionable than a single mean.
The screen
The Zephyrus G15 uses a 15.6in IPS display with a 2560x1440 resolution and a 165Hz refresh rate. On paper, this is a sensible screen specification for a premium portable gaming laptop: the resolution offers more desktop space and image detail than 1920x1080, while the refresh rate gives fast games the opportunity to look smoother when the system can supply sufficiently high frame rates. The IPS panel type is part of the specification, but the supplied facts do not provide measurements for brightness, contrast, colour coverage, response times or panel uniformity. Those qualities should not be assumed from the IPS label alone.
The central question is whether the measured performance can drive that screen effectively. At 1080p High, the answer varies sharply by game. FIFA 21 and Star Wars Squadrons both reach 198fps, exceeding the panel’s 165Hz specification in the published figures. Doom Eternal reaches 165fps, exactly matching it. F1 2020 at 162fps is extremely close. The Witcher 3 at 155fps and GTA V at 152fps also sit in a range where the 165Hz panel has obvious value.
Apex Legends at 144fps, Gears Tactics at 136fps, Battlefield V at 131fps and Dota 2 at 126fps do not match the refresh ceiling, but they remain high enough for the display to be relevant. This is the practical advantage of a 165Hz screen: it is not wasted merely because a game records 126fps rather than 165fps. A panel with that refresh rate can still present frame rates above conventional 60fps targets, assuming the relevant system and game settings support the desired output behaviour. The benchmark data does not provide those configuration details, so that should remain an assumption rather than a claim about every setup.
For games in the 70fps to 99fps range, the screen is more of a quality display than a maximum-refresh target. Mafia Definitive Edition at 99fps, Borderlands 3 at 94fps, Call of Duty Black Ops Cold War at 89fps, Metro Exodus at 85fps, Red Dead Redemption 2 at 85fps, Control at 82fps, Watch Dogs Legion at 82fps, Assassin’s Creed Valhalla at 74fps, X-Plane 11 at 72fps and Cyberpunk 2077 1.0 at 70fps are all below 165fps in the stated test conditions. The laptop can still offer good performance in those games, but the 165Hz headline should not be used as evidence that they will run at that rate.
The more significant limitation is resolution. All of the published frame-rate figures are at 1920x1080. The screen’s native resolution is 2560x1440. There are no supplied 2560x1440 benchmark figures, so there is no credible basis for stating how FIFA 21, Doom Eternal, Cyberpunk 2077 1.0 or any other listed game performs at the panel’s native setting. A buyer who insists on running everything at 2560x1440 should regard the published 1080p figures as directional evidence rather than a direct performance forecast.
That makes the display best suited to a buyer willing to treat resolution and settings as choices rather than fixed rules. The fastest games have room to take advantage of the refresh rate at the benchmark resolution. The demanding games demonstrate that there will be trade-offs at some settings, even before native 2560x1440 performance is considered. The screen is not mismatched to the hardware, but it is ambitious enough that the benchmark data needs to be read carefully.
For desktop use and non-gaming work, the 2560x1440 resolution may be attractive, but the supplied data does not include productivity measurements, colour results or screen brightness. It is safe to identify the higher resolution and IPS panel as specification features. It is not safe to claim professional colour accuracy, outdoor usability or particular content-creation suitability without those measurements.
Build, size and portability
The most concrete portability figure is the 1.99kg weight. For a laptop with an RTX 3080, Ryzen 9 5900HS, 32GB of memory, a 1TB SSD, a 15.6in QHD display and a 90Wh battery, that weight makes the Zephyrus a notably mobile proposition on specification. It is not a machine that disappears into a bag, but it is also not defined solely as a desk-bound high-performance system.
That matters because the benchmark results show a machine intended to balance performance with a more portable form factor, rather than simply pursue the highest frame rates available from the RTX 3080 name. The 1.99kg figure gives it a clear appeal for someone moving between home, work, study and travel while still wanting high-end gaming hardware. The 90Wh battery is a substantial capacity on the specification sheet, but there are no battery-life measurements in the supplied facts. It should not be turned into a claim about hours away from mains power.
Likewise, no chassis dimensions are supplied. There is no basis for describing the Zephyrus as thin, thick, narrow, compact in footprint or easy to fit into a particular bag size. Weight and display size are the available facts; anything beyond them would be speculation. Buyers for whom physical dimensions are critical should seek a confirmed dimensional specification before purchase.
There are also no supplied figures for fan noise, surface temperatures, keyboard quality, trackpad quality, port selection, webcam behaviour or internal upgrade access. Those are all areas where portable gaming laptops can differ substantially, especially when balancing high-end components against a 1.99kg weight. This review cannot claim that the machine runs quietly, stays cool, has a good keyboard or is easy to upgrade because the evidence provided does not establish any of those points.
The component specification is nevertheless strong for a buyer wanting a machine that does not look compromised in memory or storage. The Ryzen 9 5900HS is paired with 32GB of memory and a 1TB SSD. That gives the laptop a high-end baseline for the games measured and avoids the immediate concern of a minimal memory configuration alongside an RTX 3080. The supplied data does not include application benchmarks, storage speed measurements or memory configuration details, so this should not be expanded into claims about rendering, compiling, video export or SSD throughput.
The practical portability argument is therefore straightforward. Buy the Zephyrus for the combination of 1.99kg weight, 15.6in display, 90Wh battery capacity and strong published gaming results, not because there is evidence here of exceptional battery life or unusually quiet operation. Those are different claims, and the facts supplied do not support them.
How it compares
Against the MSI Prestige 15
The MSI Prestige 15 is listed with an RTX 3050 Ti at 105W. Across three shared games, the Asus ROG Zephyrus G15 averages 53fps ahead. That is the largest positive gap in the supplied rival set, and it is significant enough to make this the clearest comparison of the four.
The practical conclusion is simple: if the choice is between these two configurations and gaming performance is a central priority, the Zephyrus is in a different class on the shared-game evidence. A 53fps average lead is not the sort of difference that should be dismissed as normal variation or a minor configuration detail. The Asus has a material advantage in measured gaming output.
Neither machine has a confirmed UK price in the supplied facts, so a value comparison cannot be made. The Prestige may be relevant to a buyer with priorities not covered by the available data, but on the gaming figures supplied, the Zephyrus is the obvious choice.
Against the Schenker XMG Core 15 (M22)
The Schenker XMG Core 15 (M22) uses an RTX 3060 at 140W. Across three shared games, the Asus and the Schenker are level on average. That is a genuine result, not an error to be explained away by the RTX 3080 label.
The supplied comparison notes explain why near-zero differences can occur: at 1080p, lighter titles in the shared set can become CPU-bound and compress genuine GPU gaps. That is an important warning against over-reading this tie. It does not prove that the RTX 3060 is universally equivalent to the RTX 3080. It means that in the selected shared games under the compared conditions, the measured averages do not separate them.
For a buyer, this is a reason to look closely at the games they actually play. If their library resembles the shared titles and they are shopping on gaming performance alone, the XMG Core 15’s measured tie deserves attention. If their priorities include the Asus’s 15.6in 2560x1440 165Hz IPS display, 1.99kg weight, 90Wh battery capacity, 32GB of memory or 1TB SSD, those are specification differences to consider separately. There is no confirmed UK price for either machine in the supplied information, so neither can be declared better value.
Against the Schenker XMG Neo 15
The Schenker XMG Neo 15 is specified with a Ryzen 9 6900HX and an RTX 3070 Ti at 150W. Again, the shared-game comparison is level on average. The same warning applies: a tie in these shared 1080p games does not erase all architectural, platform or workload differences, but it does mean the Zephyrus cannot claim a measured advantage here.
This result is especially useful for shoppers tempted to assume that the Asus’s RTX 3080 automatically settles the contest. It does not. The Neo’s RTX 3070 Ti configuration delivers the same shared-game average in the provided comparison. The reason given for such compressed gaps is that lighter shared titles at 1080p can be CPU-bound. That explanation is more useful than repeating the tie without context, because it tells the buyer why GPU tiers can look unexpectedly close in some benchmark sets.
The comparison does not include confirmed UK pricing, nor does it provide a complete identical suite across all machines. It therefore cannot establish which laptop is the better purchase overall. It does establish that anyone shopping against the XMG Neo 15 should compare the individual games, display specifications, weight and other confirmed details rather than assuming the Zephyrus has an automatic GPU-led performance advantage.
Against the MSI Raider GE77 HX
The MSI Raider GE77 HX is the machine that beats the Zephyrus by the greatest margin in the supplied rival spread. It has an RTX 3080 Ti at 175W and leads the Asus by 43fps on average across three shared games. That is a major gap.
For someone whose first requirement is maximum frame rate, this is the comparison that most strongly argues against buying the Zephyrus purely for its RTX 3080 badge. The Raider’s shared-game lead indicates substantially higher measured performance. It is the appropriate choice from this limited data set for a buyer willing to choose the machine with the stronger gaming result rather than the lighter 1.99kg Asus specification.
There is no weight figure supplied for the Raider, so it would be wrong to quantify a portability difference. There is also no confirmed UK price. The decision is therefore not reducible to a value calculation. But the performance conclusion is clear: the Raider is considerably faster in the shared games, and the Zephyrus should be chosen for its own mix of performance and 1.99kg portability rather than as a substitute for the highest-output machine in this comparison group.
Who it’s for
Buy it if you want strong portable gaming performance
The Asus ROG Zephyrus G15 is for a buyer who wants a high-end specification in a 1.99kg laptop and understands the difference between strong gaming performance and universal maximum-refresh performance. The RTX 3080, Ryzen 9 5900HS, 32GB of memory and 1TB SSD make this a serious configuration, while the 15.6in 2560x1440 165Hz IPS display gives it a premium screen specification rather than a basic 1080p panel.
It is particularly well suited to players whose regular games include the faster end of Notebookcheck’s results. FIFA 21 and Star Wars Squadrons at 198fps, Doom Eternal at 165fps, F1 2020 at 162fps, The Witcher 3 at 155fps, GTA V at 152fps and Apex Legends at 144fps are the evidence for buying into the high-refresh screen. These are the titles in which the machine can best justify a 165Hz panel under the stated 1080p High benchmark conditions.
It is also a reasonable choice for players who enjoy a wide variety of games and can accept that some titles will run closer to 70fps, 80fps or 90fps than to 165fps. The likes of Metro Exodus, Red Dead Redemption 2, Control, Death Stranding, Watch Dogs Legion, Assassin’s Creed Valhalla, X-Plane 11 and Cyberpunk 2077 1.0 remain within a usable performance range in the supplied 1080p results. The buyer simply needs to be realistic about what the figures mean at the laptop’s native 2560x1440 resolution, for which no results are provided.
It is also for someone who values the option of taking a high-specification gaming system with them. The 1.99kg weight and 90Wh battery capacity are meaningful strengths on paper. The correct expectation is portability of the machine itself, not a promised battery-life figure, because no battery runtime is supplied.
Buy something else if you need the highest frame rates
Choose something else if the main goal is the highest possible gaming performance and portability is secondary. The MSI Raider GE77 HX is 43fps ahead on average across the shared games, using an RTX 3080 Ti at 175W. That is a large enough advantage that performance-first buyers should take it seriously, even though the supplied facts do not provide price or weight information for that system.
Also look elsewhere if you are buying specifically to run demanding games at 2560x1440 High while expecting to approach 165fps. The Zephyrus’s published figures are at 1920x1080, not 2560x1440. Its demanding-game results already include Cyberpunk 2077 1.0 at 70fps, X-Plane 11 at 72fps, Assassin’s Creed Valhalla at 74fps, Anno 1800 at 78fps and Crysis Remastered at 79fps. These are respectable 1080p High results with upscaling disabled, but they are not evidence for a native-QHD, 165fps outcome.
Buy something else if the RTX 3080 label is your only reason for choosing this model. The shared-game comparisons show that the Zephyrus is level with the Schenker XMG Core 15’s RTX 3060 at 140W and level with the Schenker XMG Neo 15’s RTX 3070 Ti at 150W. The reasons for those compressed results may include CPU limitations in lighter 1080p titles, but the shopping lesson remains: compare attributable game figures, not just GPU branding.
Finally, wait for confirmed pricing before making a value-led purchase. There is no confirmed UK price for the Zephyrus G15, and none is supplied for the listed rivals. Without that information, declaring any of them the better bargain would be guesswork. The Asus has enough measured performance to be attractive, and its 1.99kg weight gives it a credible portability angle, but the final recommendation depends heavily on what it actually costs in the UK.
In short, the Zephyrus G15 is a capable portable gaming laptop with excellent results in lighter and faster games, strong 1080p High performance across a broad benchmark list, and a QHD 165Hz display that it can exploit selectively rather than universally. Buy it for the balance of high-end components, 1.99kg weight and attributable gaming performance. Do not buy it on the assumption that every RTX 3080 laptop performs alike, that every game will reach 165fps, or that the published 1080p figures automatically describe native 2560x1440 gaming.
