GeForce RTX 5090 Laptop GPU: There’s probably 24GB in the laptop with 3GB GDDR7 chips 23 comments

While Nvidia will reportedly use GDDR7 for the first time in the GeForce RTX 5000 series desktop models but still use 2GB chips, the GeForce RTX 5090 laptop GPU would be the first GPU to support 3GB. GDDR7 chips. This makes 24 GB possible via the 256-bit interface of the GB203 GPU.
There are 24 GB of 256 bits in the laptop?
It is assumed that mobile GPUs from the GeForce RTX 5000 laptop GPU series will also do without the larger desktop GPU, in this case the GB202. Instead, the largest mobile graphics card, the GeForce RTX 5090 laptop GPU, will likely again use the same GPU as the desktop’s second guard: in this generation, the GeForce RTX 5080’s GB203 GPU.
As the generally well-informed and carefully expressed leaker Golden Pig Upgrade now reports on the Chinese platform Weibo, the mobile version will use a 3GB GDDR7 chip for the first time. On the 256-bit memory interface, with 8 chips 32 bits connected (8×32 bits = 256 bits), 24 GB of memory instead of 16 as in the office are possible. The larger Nvidia GeForce mobile could offer more than 16GB of VRAM for the first time since the GeForce RTX 3080 (Ti) laptop GPU.

The GeForce RTX 5090 mobile laptop GPU wouldn’t offer the same chip as its titular desktop sister model or its 32GB of memory (16×2GB on the 512-bit interface), but unlike the last generation, it would again isolate memory of the partner’s name. This was not the case with the GeForce RTX 4000.
Also more memory in the “8 GB class”?
From a gaming perspective, anything larger than 24GB instead of 16GB at the top of the laptop would be more than 8GB at the bottom of the computer. Two years ago, when the GeForce RTX 4000 laptop GPUs were released (test), 8 GB in the RTX 4060/4070 laptop GPU class was no longer enough in itself, considering the listed prices and the resolution targets WQHD – and while in Desktop they could at least spend more money on a different graphics card with more VRAM to escape the problem, but that’s just not possible in a laptop.
What the RTX 4070 and 4060 laptop GPUs have in common is that they haven’t gone through the WQHD testing course in maximum detail as worry-free as the RTX 4090 and 4080 laptop GPUs. The reason is the 8GB VRAM, which is a staple in Doom Eternal, including RT, but also eats up both graphics chips in Spider-Man Remastered and Cyberpunk 2077.
According to the test at the beginning of 2023
Nvidia is also expected to finally reveal whether there will be 12GB instead of 8GB (possibly on an RTX 5070 laptop GPU as opposed to the GeForce RTX 5060 laptop GPU) during the CES 2025 keynote tonight next Tuesday, January 7.
