NVIDIA GeForce RTX 5000 Series Blackwell GPU Lineup Specs Leaked


NVIDIA GeForce RTX 5000 GPU Blackwell Series: Leaked Specs

Last week, renowned leaker Kopite7kimi dropped a tantalizing hint: the configuration of the GB203 GPU differs from what was initially believed. Instead of the expected 96 Streaming Multiprocessors (SMs), the actual design features 84 SMs. While the leaker didn't confirm the exact configurations of the remaining GPUs at that time, today we have the full scoop on all five upcoming Blackwell GB20X processors.

GB202: The Flagship Contender

The GB202, poised to be the flagship GPU, is anticipated to pack a punch with its 12 Graphics Processing Clusters (GPCs) and 8 Texture Processing Clusters (TPCs) per GPC. This configuration results in a total of 192 SMs (assuming 2 per TPC). However, it's essential to note that NVIDIA might tweak this setup for the retail SKU to optimize yields. Additionally, the memory bus is expected to be 448 bits wide, even though the GPU theoretically supports a 512-bit bus.

GB203: A Balanced Approach

The GB203 takes a different approach with its 7x6 configuration, yielding a total of 84 SMs. Interestingly, this GPU shares a 256-bit memory bus with the AD103 GPU, making it a close sibling. Notably, GDDR7 memory support is a new feature here.

GB205: A Downgrade from Ada Lovelace

The GB205, positioned as the successor to the AD104, features a 5x5 configuration, resulting in 50 SMs. Unfortunately, this represents a downgrade from the 60 SMs found in the AD104 on the Ada Lovelace series.

GB206 and GB207: The Compact Siblings

Kopite7kimi sheds light on two more Blackwell GPUs: GB206 and GB207. Both GPUs sport a 128-bit memory bus, but only GB206 boasts GDDR7 memory. The configuration of GB206 aligns with that of the AD106, while GB207 features 20 SMs-a slight reduction from the 24 SMs seen in the AD107.

  • GB202: 12×8 = 192 SM (+33% vs AD102), 512-bit GDDR7
  • GB203: 7×6 = 84 SM (+5% vs AD103), 256-bit GDDR7
  • GB205: 5×5 = 50 SM (-17% vs AD104), 192-bit GDDR7
  • GB206: 3×6 = 36 SM (no change vs AD106), 128-bit GDDR7
  • GB207: 2×5 = 20 SM (-17% vs AD107), 128-bit GDDR6

Launch and Expectations

The NVIDIA GeForce RTX 50 series is slated for an early 2025 release, although the official announcement may occur sooner. While Blackwell doesn't promise groundbreaking upgrades over Ada Lovelace, it's still an exciting glimpse into NVIDIA's next-gen offerings.

Stay tuned for further updates as we inch closer to the official launch! 🚀
