Those RTX 5090 numbers are bad. You can get over 200 tps with ninfer using NVFP4 and MTP.
The issue is that the moment you want to run the more capable models that will no longer fit in a single 5090's memory, performance falls off a cliff.
Both are probably single-token decode performance, which is reasonable to show. Otherwise agree RTX 5090 should shinebetter with NVFP4.
... or with llama.cpp with MTP.
can confirm.
I dont' know why people spend huge money on these and Spark. The 5090 is running qwen 3.8 at 200+ tps!! That's 1-2 orders of magnitude faster.
