More spec and benchmark leaks are beginning to surface online as the projected release of Nvidia Lovelace later this year approaches, and boy howdy, the flagship Lovelace card may be an absolute monster of a GPU.
The most recent report comes from Twitter hardware leaker kopite7kimi, who says Nvidia is testing a variant of its AD102 GPU with 18,176 CUDA cores, which is approximately double the number of cores found in the Nvidia RTX 3090 Ti, the best consumer graphics card in terms of raw performance.
If the rumours are true, Kopite7kimi’s moniker is appropriate. According to Lovelace’s power-hungry design, the AD-102-450-A1 GPU will have 18,176 CUDA cores, 48GB of GDDR6X VRAM, and 800W of TGP.
These specs give further information. Because each stream multiprocessor (SM) should have 128 CUDA cores, the card should have 142 SMs. Nvidia Ampere has 142 ray tracing cores if each SM has one.
If Lovelace follows Ampere’s lead and uses four tensor cores per SM, the card will have 568 tensor cores to speed up machine learning and ray tracing. This is a 70% improvement over the RTX 3090 Ti, while actual performance gains may be higher.
We don’t know if this is an engineering sample of the RTX 4090 Ti or another high-end BFGPU. We heard of a Titan-class AD102 GPU with more cores and TGP a few months ago, but this would most likely be a workstation graphics card.
This new design will be a consumer card for high-end gaming PCs and workstations.
