Fields marked "not published" are ones the vendor does not state. We leave them blank rather than estimate.
Board power covers the GPU card alone; whole-machine power covers the complete computer. A card's rating excludes the rest of the system. See our power, cooling, and noise guide for power-supply planning.
What it can run
Whether a model's weights fit in 24 GB, with a 20 percent allowance for the KV cache, activations, and the runtime. This is arithmetic on the quantization format, not a benchmark. Long contexts and large batches need more.
At Q4, the smallest format below, 17 of the 25 models we size fit on this machine.
