Prices verified July 2026.
Every number, explained
- GPU memory
- 32 GB GDDR6
GPU memory is the workbench — the whole model must fit here or it doesn't run at all. Regular RAM cannot substitute: it sits on a link far too slow for the GPU, which would spend nearly all its time waiting instead of computing.
- Memory bandwidth
- 512 GB/s
TODO: verify
How fast the GPU re-reads the model from its own memory. To generate every single word, the GPU re-reads the ENTIRE model — all of it, every word. So faster memory means faster answers: double the bandwidth and the model talks roughly twice as fast.
- Power draw
- 300 W — about 0.25 of one home's constant draw (a home draws ~1,200 W around the clock); one day (7.2 kWh) drains about 0.08 EV battery (an EV battery holds ~90 kWh).
Electricity burned every second the machine runs — this is a real monthly bill, not a spec-sheet footnote. We translate it below into homes and electric-car batteries so you can feel the size of it.
- Form factor
- Desktop/server PCIe card
The CPU is the traffic director — it does almost none of the AI math. Don't overspend here; the GPU does the work.
- Price
- ~$1,399
