GPU TGP
The wattage a laptop feeds its GPU; higher TGP usually means more performance from the same GPU model.
TGP (Total Graphics Power) is the maximum sustained power, in watts, that a laptop delivers to its discrete GPU. The same RTX 5080, for example, can be configured anywhere from roughly 95W in a thin chassis to 150W or more in a thick gaming model, and the higher-wattage version is meaningfully faster.
NVIDIA stopped printing TGP on the box, so two laptops with the identical GPU name can differ by 20-30% in gaming performance. Reviewers and spec sheets usually list the configured wattage, sometimes shown as 'Max Graphics Power'.
Why it matters when buying
Always check the configured TGP, not just the GPU name. For desktop-class performance look for GPUs near their maximum rated wattage paired with strong cooling; in thin-and-light laptops a lower TGP is the trade-off for portability.
