Laptop GPU power (TGP): the wattage each gaming laptop gives its RTX 50 chip

Two gaming laptops can carry the same “RTX 5070” badge and give it very different amounts of power. The badge is the chip; the watts are the laptop. This page explains the figure and lists it for every laptop in our catalogue whose maker publishes it. We don’t benchmark laptops, so there are no frame rates here: those belong to labs that measure them, such as Notebookcheck.

What TGP is

A laptop’s cooling and power adapter limit how much electricity its graphics chip can turn into heat. The maker sets that limit, and it is usually written as TGP, total graphics power, in watts.

NVIDIA publishes the range it allows for each chip as “GPU Subsystem Power”. For the RTX 50 series laptop chips, its comparison table reads:

The top of a range is nearly double the bottom for most chips, and three times for the RTX 5050. That spread is the reason the chip’s name alone isn’t enough.

Makers’ figures often run higher than NVIDIA’s ceiling because they add Dynamic Boost: power moved to the graphics chip when the processor has some to spare. ASUS writes the sum out on its specification pages: the ROG Strix G16’s RTX 5080 is “150W+25W Dynamic Boost”, 175 W; its RTX 5070 is 100 W plus 15 W, 115 W.

Graphics power by laptop

The wattage in brackets is the highest the maker states for that graphics option in that chassis.

What the table shows:

• Thick chassis run the chip at full power. The Lenovo Legion Pro 7 and the ROG Strix G16 give the RTX 5080 175 W. They are 1.05 in and 1.21 in at their thickest and weigh 5.67 lb and 5.84 lb.
• The thin one gives some up. The ROG Zephyrus G16 is 0.7 in at its thickest and 4.3 lb, 1.54 lb lighter than the Strix G16. ASUS lists its RTX 5080 at 160 W in Manual mode and 135 W in Turbo mode, and its RTX 5070 Ti at 140 W and 125 W. Its memory is also soldered, where the Strix has two slots.
• Lenovo’s mid-range sits at 115 W. The Legion 5 lists 115 W for both the RTX 5060 and RTX 5070.
• The entry model uses an older chip. The LOQ Essential 15, the LOQ that Lenovo sells in the US, has the previous generation’s RTX 3050 at 75 W, with 4 or 6 GB of graphics memory.
• Some makers don’t publish it where buyers look. Dell’s product page for the Alienware 16 Aurora and Lenovo’s sheet for the ThinkPad P16 workstation (RTX PRO graphics) give no wattage.

How to use the number

1. Compare like with like. TGP separates two laptops with the same chip. It doesn’t rank a 5070 against a 5080.
2. Read which mode the figure is for. ASUS quotes different wattages for Turbo and Manual modes on the Zephyrus G16. The top figure may need a setting changed and the fans at full speed.
3. Look at the adapter. The power adapters listed for these laptops run from 135 W (LOQ Essential 15) and 245 W (Legion 5) to 400 W (Legion Pro 7). A high TGP only applies when plugged in.
4. Then find measurements. A lab review of the exact model tells you what the watts turn into.

What else the chassis decides

The same documents settle the other things reviews of gaming laptops tend to skip: whether there’s an Ethernet port (every gaming model here with a documented port list has one), how much it weighs, and how deep it is for your bag.
