New information on the NVIDIA AD102 graphics processor surfaces.
NVIDIA Lovelace AD102 GPU
A week ago we reported that NVIDIA will introduce a new graphics architecture named after Ada Lovelace. The series is expected to be NVIDIA’s next gaming architecture that could arrive even before Hopper.
The architecture codenamed Lovelace would see an increase in Graphics Processing Clusters up to 12, which is twice as many as Turing’s GA102 GPU has. This is according to the new tweet from a well-known and proven leaker @kopite7kimi. This means that the GPU could hold as many as 72 Texture Processor Clusters (TPCs) and 144 Streaming Multiprocessors. With 144 SMs, the GPU could see as many as 18432 CUDA Cores (144 x 128), 71% more than GA102 GPU.
It is unclear when would the new architecture be released. Kopite7kimi has started sharing information on this architecture only this month, so it appears to be rather a fresh topic. It could also never happen, as roadmaps tend to change quite frequently at NVIDIA HQs.
NVIDIA Lovelace AD102 GPU may arrive under GeForce RTX 40 series, possibly after RTX 30 SUPER refresh (which has not been confirmed yet). NVIDIA is now expected to refresh its lineup (only 3 months after release) with RTX 3080 Ti and RTX 3070 Ti graphics cards next quarter.

So, nVidia's AD102 chip maybe is like:
12 GPC
72 TPC
144 SM
18'432 FP32 units
~66 TFlops FP32 power (on 1.8 GHz) https://t.co/A8OnUktE1s— 3DCenter.org (@3DCenter_org) December 28, 2020
