NVIDIA has tested a prototype GPU dubbed RTX 5090 Ti or Blackwell Titan since mid-2025, featuring 22,848 CUDA cores but not the full GB202 chip. Power draw reaches 700-750W normally and over 1000W unlocked, requiring massive cooling. Performance is only 10-20% above RTX 5090, and release is unlikely.
Key Points
- 1.22,848 CUDA cores, 5% more than RTX 5090 but short of full GB202's 24,576
- 2.Normal power 700-750W, unlocked prototype exceeds 1000W
- 3.Requires enormous cooler, described as 'handheld with both hands'
- 4.Performance gain ~10% typical, up to 20% in ideal conditions
- 5.Prototype exists but likely never to release like past Titans
Impact Analysis
This highlights diminishing returns in GPU scaling, pushing AI infrastructure toward efficiency over raw power. High TDP could strain data center power supplies, influencing procurement decisions for training clusters.
Technical Details
Uses partial GB202 die closest to RTX PRO 6000's 24,064 cores. Compared to MSI RTX 5090 Lightning at 1000W yielding 13% FPS uplift in games.
