GeForce RTX 5090 Notebook GPU modification increases performance by up to 40%

Although suitable for testing, such as GizmosLiptech experiments, shunt mods are not recommended for regular use. In the end, Exceeding the nominal limits of the video card always involves damage risks.

In addition, electronics knowledge is required to perform this task.

Modified GPU

The modification was made at a GeForce RTX 5090 for notebooks, which uses the same GB203 of Nvidia’s Blackwell -top video cards. The GPU for GeForce RTX 5090 notebooks has 10,496 CUDA nuclei, just a few less than GeForce RTX 5080.

However, it is not the same GPU RTX 5090 for desktops.

As it is a mobile component, it also has lower clock speeds, limited by a lower power limit. Typical GPUs for GeForce RTX 5090 notebooks feature a TGP between 95 W and 150 Wplus 25 W Additional Nvidia’s Dynamic Boost technology.

With the mod, Youtuber increased TGP to 250 W, 43% more than the original value.

Test results

The test was performed in a Notebook Gamer Eluktronics Hydroc 16 G2 with a Core Ultra 9 275hx and a GPU for GeForce RTX 5090 notebooks. The device also has 48 GB (2 × 24 GB) of DDR5-7200 memory. Several settings have been tested.

On average, the GPU for GeForce RTX 5090 notebooks presented 18% higher performance. Analyzing the individual results, The increase in performance ranged from 4% to 41%.

In intensive processor games such as Shadow of the Tomb Raider, the improvements were minimal. YouTuber registered 4% better average frame rates in the title mentioned.

Already in titles with GPU restriction the improvements were quite noticeable. For example, average frame rates in Black Myth Wukong, Witcher 3, Tom Clanc’s Rainbow Six Siege and Cyberpunk 2077 improved by more than 20%.

Market Options

For interested users, XMG expressed enthusiasm in supporting higher TGP limits higher on Nvidia GPUS notebooks. However, the decision of Nvidia still remains. On the part of XMG, current cooling solutions of the brand already offer a significant thermal margin.

That is, the GPUS GeForce RTX 5080 and GeForce RTX 5090 for notebooks within XMG NEO 16 They work below 80 degrees Celsius with air cooling and below 70 degrees Celsius with the XMG Oasis liquid cooling system.

As, in either case, the temperatures of the video cards are below the 87 -degree Nvidia guidelines, Celsius, There is margin for increased TGP without prejudice to cooling.

This is because Some gamers notebooks are designed with additional cooling methods to support higher energy limits that users should use.

This does not mean that partners can circumvent Nvidia’s restrictions and increase the power limit to give their products a competitive advantage over competitors. NVIDIA that establishes the guidelines of its products and the partners must follow them.
