According to insider kopite7kimi, the GPU is GB100 Blackwell for the data center will use 10 TPCs (texture processing clusters) in each of 8 SMs (streaming multiprocessors). This configuration implies an increase in the total number of cores compared to the GH100 (8×9), unless NVIDIA decides to change the CUDA circuitry in these TPCs, which seems unlikely at the moment.
What’s even more noteworthy is that details about the GB202 GPU configuration have also been hinted at. It reportedly includes 12 SMs of 8 TPCs each, resulting in a total of 192 SM. While the GB1XX family of GPUs is aimed at data centers, the GB2XX series is clearly intended for gaming solutions and possibly workstations. It will form the basis of NVIDIA’s next generation gaming chip. Unfortunately, information about the design of tensor and RT cores remains undisclosed at the moment.
This 192 SM configuration corresponds to 24576 CUDA kernels unless changes are made in the future. This represents a remarkable 1/3 increase over the AD102 Ada Lovelace GPU, which is currently the flagship of the RTX 40 series. However, it is worth noting that at this point, with no sign of the RTX 4090 Ti, NVIDIA has not yet fully exploited the entire quantity (144 SM) is for gaming purposes, with the closest offering being the RTX 6000 ADA model with 142 SM included.
More importantly, the source confirms earlier rumors of inclusion 512-bit memory bus in the GB202 GPU. It’s worth noting that this configuration may not be used in the RTX 5090. Assuming the RTX 50 series actually uses memory technology GDDR7this will naturally lead to a significant increase in memory bandwidth.
NVIDIA’s roadmap suggests that the successor to Ada Lovelace will be released in 2025, but some rumors suggest it could happen sooner. The exact configuration of the RTX 5090 GPU is, of course, impossible to imagine yet. Moreover, other sources report that the NVIDIA GB202 has not yet been discontinued and variants could still be chosen instead. However, given the track record and insider confidence, NVIDIA is moving towards finalizing the specifications of its next-generation flagship gaming GPU.
