Leaked: NVIDIA GeForce RTX 50 “GB202” GPU to Boast 192 SMs and 512-bit Memory Bus

September 28, 2023 by our News Team

.com The upcoming NVIDIA Blackwell flagship gaming GPU is rumored to feature 192 Streaming Multiprocessors, 24,576 CUDA cores, and a 512-bit memory bus, potentially resulting in a considerable boost in memory bandwidth.

  • Potential increase in total core count compared to GH100
  • GB202 GPU to feature 12 SMs with 8 TPCs each, resulting in a total of 192 SMs
  • 512-bit memory bus in the GB202 GPU

GB202 to feature 192 Streaming Multiprocessors

The latest rumors from trusted nVidia leaker, Kopite7kimi, shed light on the upcoming Blackwell flagship gaming GPU. According to Kopite, the GB100 Blackwell data-center GPU will employ 10 TPCs (Texture Processing Clusters) within each of its 8 SMs (Streaming Multiprocessors). This suggests a potential increase in the total core count compared to GH100.

But what’s even more interesting is the hinted configuration of the GB202 GPU, which is said to feature 12 SMs with 8 TPCs each, resulting in a total of 192 SMs. It’s important to note that while the GB1XX GPU family is designed for data centers, the GB2XX series is specifically intended for gaming and potentially workstation applications, promising an enhanced gaming experience from NVIDIA.

Unfortunately, details about the design of Tensor and RT Cores remain undisclosed at this point. However, the 192 SM setup in the GB202 GPU translates to a significant increase of 24,576 CUDA cores compared to the current flagship RTX 40 series. This represents a noteworthy 1/3 increase in core count.

Kopite also reaffirms earlier rumors about the inclusion of a 512-bit memory bus in the GB202 GPU. It’s worth noting that this configuration may not be utilized in the RTX 5090. If NVIDIA adopts GDDR7 memory technology for the RTX 50 series, it would result in a considerable boost in memory bandwidth.

While NVIDIA’s roadmap initially indicated a 2025 launch for the successor to Ada Lovelace, there are rumors suggesting it may arrive sooner. The exact configuration of the RTX 5090 GPU remains unknown at this stage, and there may still be variants under consideration. However, given Kopite’s track record and confidence, it seems NVIDIA is finalizing the specifications for its next-generation flagship gaming GPU.
