NVIDIA is prepping to upgrade its GeForce RTX 50 series “Blackwell” GPUs with larger VRAM buffers as part of the mid-cycle Super refresh. Offering marginal generation uplifts, the latest RTX lineup is itself more of a refresh than a new architecture. Multi Frame Generation “multiplies” frame rates, but it requires a fair amount of VRAM; it’s only fair that the GPU memory be expanded.
NVIDIA RTX 5070 Super: 12 GB -> 18 GB
The GeForce RTX 5070 is the most popular Blackwell SKU, outselling its peers three-to-one. Unfortunately, it’s hardly faster than the RTX 4070 Super, offering the same 12 GB VRAM buffer at a higher power budget. Ergo, it’s not surprising that this midrange champ is getting the most prominent upgrade.
The GeForce RTX 5070 Super will feature a larger 18 GB VRAM buffer, more cores, and a higher power budget than the base model:
- The shader count will be bumped to 6,400, up from 6,144 on the RTX 5070, encompassing the fully enabled GB205 die.
- The RT and Tensor Core/Texture Units will also get upgraded to 50 (up from 48) and 200 (up from 192), respectively.
- The memory chips will be upgraded to 3 GB (up from 2 GB) per package. The memory clocks and bandwidth will remain unchanged.
- The TBP (Total Board Power) will be scaled up from 250W to 275W.
NVIDIA RTX 5070 Ti Super: 16 GB -> 24 GB
The RTX 5070 Ti Super will get 50% more memory than the base variant. The shader count won’t change, but the TBP increase hints at higher core clocks:
- The VRAM will increase from 16 GB to 24 GB using 3 GB memory chips.
- The memory clocks and bandwidth won’t change.
- The core clocks will likely get an uplift.
- The TBP will be increased from 300W to 350W.
NVIDIA RTX 5080 Super: 16 GB -> 24 GB
- The RTX 5080 Super is also getting a larger memory buffer, increasing its VRAM capacity from 16 GB to 24 GB.
- It’s also getting higher clocked 32 Gbps memory dies, offering a mild bandwidth uplift.
- The core clocks should also be beefed up.
- The TBP will go over 400W.
There’s no word on Super variants for the RTX 5060 and the 5070 Ti. While the latter comes in 8 GB and 16 GB variants, the former is limited to an 8 GB buffer. The 60-class cards form the majority of the PC gamer market share, and it would be a shame if NVIDIA ignores such a large audience.
