Compare the hardware
Tap products on and off and watch the bars redraw. Four honest lenses: the memory that decides what fits, the price you pay once, the power you pay for forever, and how much memory each $1,000 actually buys.
How to read these bars
The single most important number. A model's 'weights' — its entire brain — must fit inside the GPU's own memory all at once, or the model simply will not run. If a model needs 282 GB and your cards add up to 240 GB, it doesn't run slowly, it doesn't run at all. This is the number that decides what you can buy.
Watch for the trap: the desktop card wins the memory-per-dollar bar — but as the honest cluster note on every build explains, a pile of desktop cards can't team up fast enough to run one big model. Value per dollar only counts if the hardware can actually do the job.
