- The RTX 5090 laptop GPU will allegedly have 24 GB of GDDR7 VRAM, as claimed by a prolific industry leaker.
- Such a massive VRAM upgrade is possible over 4090 because the GPU will feature 3 GB GDDR7 memory modules.
- All this can be achieved despite only having a 256-bit memory bus. Take the rumors with a pinch of salt.
Nvidia is expected to reveal its RTX 50 series line-up of GPUs in the upcoming CES 2025 event, so the hype is through the roof. Gamers are also excited to see the specs of the new laptops that will utilize the flagship GPU in the Blackwell series. However, a massive leak might have unveiled one of the most exciting and unexpected upgrades for the RTX 5090 mobile variant over the 4090.
An insider has revealed that the 5090 laptop GPU could have 24 GB of VRAM instead of only 16 GB, which has become a huge possibility thanks to an unexpected upgrade in the memory modules.
Why it matters: RTX 5090 laptop GPU utilizing the 3 GB GDDR7 memory modules could enhance its performance by a mile, making 24 GB GDDR7 VRAM possible instead of only 16 GB memory.
The leaker Golden Pig Upgrade mentions on Weibo that the RTX 5090 mobile GPU’s VRAM can rise to 24 GB because it will use 3 GB GDDR7 memory modules. This can make the GPU reach as high as desktop RTX 4090 in VRAM while using the same 256-bit memory bus.
The massive VRAM upgrade will likely not make much of a difference in games, except for some extreme AAA exceptions at 4K resolution.
Of note is that no other GPU has been confirmed or rumored to be utilizing the 3 GB GDDR7 memory module configuration, making the laptop RTX 5090 the only one for now. It is also rumored to use the GB203 die instead of the GB202.
The mobile RTX 5090 is also expected to have about 10,752 cores, only half the amount of the desktop variant. It is best to take these speculations with a pinch of salt despite the track record of the Chinese leaker.
Do you think RTX 5090 laptop GPUs will take advantage of the increased memory modules to use 24 GB of VRAM? Let us know your thoughts in the comments below, or join the discussion on the official Tech4Gamers forum.
