The specifics
- Chip
- Corsair AI Workstation 300 — Ryzen AI Max+ 395 · Radeon 8060S, 40 CU
- Memory bandwidth
- 256 GB/s
- Usable by the GPU
- 96 GB — Corsair lists up to 96 GB VRAM for this configuration, the Windows 75% split used for the other Strix Halo machines. On Linux the GTT pool can be raised to roughly 108-120 GB. Measured GPU bandwidth is ~212-215 GB/s of the 256 GB/s theoretical, so estimates here run a little high.
- Power under load
- 133 W (stand in) — No wall measurement for this unit; stand-in is the Framework Desktop's measured 133 W on the same chip (Jeff Geerling). Tom's Hardware reports Corsair's firmware profiles give the chip about 85 W (Balanced, default), 120 W (Max) or 55 W (Quiet).
- Availability
- Corsair's price on 2026-09-16, backordered. Was $2,999.99 in February 2026.
