Nvidia announces GPU with support for up to 128GB VRAM, but not for this generation
Table of Contents
Nvidia has unveiled a brand new GPU with 128GB of VRAM, due to be released by the end of 2026. There have been rumors and ‘leaks’ over the past couple of days about a GeForce RTX 5090 GPU with 128GB VRAM, however, as we reported, these were almost certainly false, given the image in question showed the card operating on a 550.144.03 Driver Version, which is not supported by Blackwell architecture (it uses the 570 branch and newer).
Yesterday, on September 9th, 2025, NVIDIA introduced a new GPU called Rubin CPX, designed to process extremely large chunks of data (over one million tokens) for complex AI tasks like generating video or building software that uses code across many files. As you can see in the image below, this card does indeed come with 128GB of GDDR7 VRAM.
This thing is, it’s not for gamers or general consumer use – this is purely a commercial AI-focused chip. We’ll have to wait and see what specs the upcoming contenders for best graphics cards for gaming will bring, but to be honest, it seems unlikely that we’ll see a leap from 32GB of VRAM to 128GB; 48GB or 64GB is more likely for any future RTX 6090.

What new gaming GPUs can we expect to see in 2026?
From Nvidia, the expected 50-series Super cards will most certainly be built on the same Blackwell architecture, which could actually release as early as December 2025 (in the case of the RTX 5070 Super and RTX 5070 Ti Super), but with the RTX 5080 Super likely landing in Q1 2026 at some point – probably after the CES conference in January. Beyond that, the 60 series should feature the Rubin architecture.
As for AMD’s range, Moore’s Law Is Dead (a leaker of some repute) says that the next-gen RDNA 5 Radeon cards are probably due between 2026-2027 (quite a large margin), including a possible Radeon RX 10090 XT flagship to combat a future Nvidia RTX 6090. In the meantime, the release of FSR Redstone at the end of this year may help the current crop of Radeon graphics cards better compete with Nvidia’s in terms, especially if AMD has plans to release something like an RX 9080 XT.
The above are all based on rumors and leaks, of course. Nothing is confirmed, so take it with a pinch of salt.
