One number decides it: usable memory for the model. Pick a model and a quality level — every device below is checked against that single feature first, then compared on everything else: speed, screen, weight, ports. Prices live on the detail pages and at the retailer; the ranking never depends on them.
Usable memory is what is left for the model itself. A graphics card uses all of its VRAM; a unified-memory device shares memory with the system, so about 75 percent of it can hold a model. The bar shows the selected model against that usable memory.
96 GB usable. Holds a 70B model at Q4 quality — unified memory, no spill to slow system RAM.
36 GB usable. Holds a 32B model at Q4 quality — unified memory, no spill to slow system RAM.

12 GB usable. Holds a 14B model at Q4 quality — dedicated vram memory, no spill to slow system RAM.
8 GB usable. Holds a 8B model at Q4 quality — dedicated vram memory, no spill to slow system RAM.
Pick up to three. The winner of each row is marked; the answer underneath says why, starting with the memory feature and then the rest of the device.
Sorted by usable model memory — the feature that decides which models a device can run at all.
