Possibly these are the characteristics of the new NVIDIA
So far, everything passed through the sifter tells us about the GPU: how much memory it has and what kind, how many CUDA Cores are inside. Now, the honest truth would be that with only those alone, most data is missing to know the final specifications—frequencies, Tensor Cores, and so on. We can presume—even with little knowledge about them—that there will be a lot of data in comparison with the previous version.
They show us the possible names of silicon for the NVIDIA RTX 5000 Series with Blackwell architecture. At the other end, we have as the most powerful GPU the GB202, to which we would have to add GB203, GB205, GB206, and GB207.
Noticeably, it will be the GB202 silicon destined for the new RTX 5090 that could become probably the first to hit the market. The rumormonger has it that this chip would pack a total of 192 Streaming Multiprocessors and 96 Texture Processing Clusters. Provided it contains 96 TPCs, this number would then be divided into a total of 12 Graphics Processing Clusters—each containing a total of 8 TPCs.
The RTX 5090 will be based on new GDDR7 memory and will come with a 512-bit memory bus. Its memory speed was unknown, but it is running at 28 Gbps. Assuming the confirmation is correct, this will mean that the top end card from NVIDIA reaches all of the way up to 1,792 GB/s in bandwidth.
This would now be GB203 with a count of 7 GPCs and a count of 42 TPCs, bringing the total count of CUDA Cores to 10,752. This is going to be complemented by GDDR7 memory featuring a 256-bit memory bus operating at a speed of 28 Gbps for an effective bandwidth of 896 GB/s.
The more mainstream-oriented GB206 would, however, run with 5 GPCs and 5 TPCs for a total count of 6,400 CUDA Cores. It equips with GDDR7 featuring a 192-bit memory bus running at 28 Gbps memory speed with 672 GB/s bandwidth.
It comes with 3 GPCs and 8 TPCs and packs a total of 6,144 CUDA Cores. The memory remained GDDR7;, though the memory bus has been reduced to a 128-bit; the speed, however, remains at 28 Gbps for reportedly delivering 448 GB/s bandwidth.
This finally only has 2 GPCs and 5 TPCs for a grand total of just 2,560 CUDA Cores on the GB207. As such, this silicon will be paired with GDDR6 memories on a 128-bit bus at a speed of 18 Gbps for 288 GB/s of bandwidth.
