AI chips compared

For running AI models locally, two chip specs matter most: how much memory the graphics side can use, and how fast it can read it. NPU speed matters far less.

"Largest model it holds" assumes the chip's biggest memory option, a long (8,000-token) conversation and 4-bit models from our calculator's catalog. Memory bandwidth is the maker's theoretical peak; see our bandwidth study for how it translates into speed.
