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.
