RTX PRO 6000 MoE Benchmark: 50.5 tok/s Max
💡Real-world 50.5 tok/s on 397B MoE + NVIDIA SM120 bugs exposed
⚡ 30-Second TL;DR
What Changed
Marlin TP=4 achieves 50.5 tok/s sustained—best on SM120 hardware.
Why It Matters
Highlights NVIDIA validation gaps on workstation Blackwell, capping FP4 throughput. Guides inference optimization toward Marlin over broken CUTLASS for consumer GPUs.
What To Do Next
Benchmark Marlin TP=4 on your SM120 setup before trying CUTLASS or MTP.
Key Points
- •Marlin TP=4 achieves 50.5 tok/s sustained—best on SM120 hardware.
- •CUTLASS grouped GEMM fails on RTX PRO 6000 (SM120), bug filed #3096.
- •MTP=2 slows Marlin from 50.5 to 39.6 tok/s due to dequant mismatch.
- •No NVLink PCIe setup limits expert parallel to 1.4-2.6 tok/s.
