This morning I attempted to push the wattage of the GB10 (MSI 4TB variant) as high as possible.
Sascha Willems’ indirectdraw Vulkan demo reports 87W using nvidia-smi/nvitop running fullscreen at 3840x2400.
Wall power is 180W with a 14” portable USB-C OLED monitor attached (~10W).
[ Edit: What is consuming ~83W of power? ]
Temp has peaked at 80C.
Simultaneously running a llama-server query decreases the reported GPU power to 80W while system power remains unchanged… and temperature drops to 79C.
The MSI GB10 remains whisper quiet but the air out the back is nice and toasty.
I wish Nvidia would fix the power reporting. There’s just no way it’s accurate. Someone at Nvidia forgot to multiply the power reading by 2x or some similar oversight.
@NVES I understand the clarification, but I don’t agree that it is accurate. Even in a GPU-only task that is using at most 1 CPU core, with no devices connected via USB, the power drawn at the wall is entirely disconnected from what nvidia-smi measures.
I would like to see Nvidia publish some actual holistic test results showing that nvidia-smi is accurate, because it does not feel accurate even for just GPU power consumption.
