NVIDIA Jetson AGX Thor 128GB vs NVIDIA RTX Pro 6000 Blackwell for local LLMs
4 reports on the NVIDIA Jetson AGX Thor 128GB and 51 on the NVIDIA RTX Pro 6000 Blackwell
Which is faster for local LLMs?
On Qwen3.8 125B · 6B active at 4-bit, the NVIDIA Jetson AGX Thor 128GB runs at 36.7 tokens per second (one run) and the NVIDIA RTX Pro 6000 Blackwell at 101.9 (5 runs). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 6.6x higher on the NVIDIA RTX Pro 6000 Blackwell (273 GB/s on the NVIDIA Jetson AGX Thor 128GB, 1,792 on the NVIDIA RTX Pro 6000 Blackwell).

Measured on both
Median tokens per second from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same quant level. Engines and context lengths can still differ between the runs. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
