Can a Strix Halo Corsair AI Workstation 300, 64GB run local LLMs?

Yes — 33 of the 49 current models on this site fit in its 48 GB of usable memory. The strongest it holds, Qwen3.8 27B, runs at 10 tok/s with a 32k window, worked out from memory bandwidth. Whether that saves you money is a different question: at $1,700 and 500k tokens a day, it pays back in 121 years.

What the Corsair AI Workstation 300, 64GB runs

They do not all hold the same window. The weights are a fixed size, but the key-value cache grows with every token you keep, so what is left of 48 GB after the weights is how far the context goes. On one of the 12 below, this machine's memory is what runs out first: Granite 4.2 30B stops soonest, at 64k. The rest reach 256k, where the calculator's list ends, or the longest setting their own context limit allows.

Speed and memory are at 32k context, the setting the calculator starts on; the memory column is the weights plus the cache for that much of it. Each speed says how it was arrived at, and every one here is estimated from this machine's 256 GB/s of memory bandwidth rather than taken from a published benchmark. There is a page on how that sum works, and what each size needs, and one on what 64 GB runs, machine by machine. The longest context is the longest setting the calculator offers that this machine still holds the model at, cache included, and each one opens the calculator on that model at that length. A figure tagged memory is one this machine ran out of room for, and the rest are stopped by the model's own limit or by the end of the list.

For scale, the calculator starts from 80 tok/s for a hosted API and times a local machine against it. Nothing above reaches it, and the quickest is 56 tok/s.

The 49 counted above are the current models. This site prices 16 superseded ones as well, because people still run them, and this machine holds 11 of those at 32k, strongest first: Qwen3 30B-A3B Instruct 2507, DeepSeek-R1-Distill-Qwen-32B, Llama 3.1 8B Instruct at Q4_K_M, Llama 3.1 8B Instruct at Q8_0, Mistral Small 3.2 24B Instruct, Qwen3 32B at Q4_K_M, Qwen3 32B at Q8_0, Qwen3 14B, Qwen3 8B, Gemma 3 27B it, Gemma 3 12B it.

Every row uses the same defaults as the figures above: 500k tokens a day at 15:1 input to output, 32k context, and each machine's strongest model that fits, counted against the same 49 current models. Graphics cards are priced as the card alone, so add the PC around one before comparing it with a complete computer. All seven cards here are ranked by what each one holds.

Head to head with another computer: Mac mini M5 Pro, 24GB. With the same box and the bigger chip: 128GB. There are 111 machine match-ups on the site.

The specifics

Chip
Corsair AI Workstation 300 — Ryzen AI Max 385 · Radeon 8050S, 32 CU
Memory bandwidth
256 GB/s — Measured GPU bandwidth on Strix Halo is ~212-215 GB/s of the 256 GB/s theoretical, so estimates here run a little high.
Usable by the GPU
48 GB — Windows lets you dedicate up to 75% of RAM to the GPU; Corsair lists up to 48 GB VRAM for this configuration.
Power under load
133 W (stand-in) — No measurement for the Max 385 system; stand-in is the Max+ 395 Framework board's measured 133 W, which likely overstates this smaller GPU.
Availability
Corsair's price on 2026-09-16, out of stock. This tier uses the smaller Ryzen AI Max 385.
