System76's Thelio Mira AI Tops Out at 192GB of GPU Memory, $40,538

System76 launched the Thelio Mira AI on Thursday, a Linux desktop workstation built around AMD Ryzen 9000-series processors and a choice of GPUs that scales from a single 4GB card to two Nvidia RTX Pro 6000 units carrying 192GB of combined video memory, according to System76's own product page.

The base configuration costs $3,299: an eight-core Ryzen 7 9700X, a single Nvidia A400 with 4GB of memory, 64GB of DDR5 RAM and a 1TB PCIe Gen5 NVMe drive. Notebookcheck reported that the dual RTX Pro 6000 configuration adds $37,239 on top of that base, putting the machine's ceiling above $40,000 before tax.

The number that matters is memory per GPU, not GPU count

A large language model that will not fit in one card's memory has to split across cards, which adds interconnect latency every layer that crosses the split. System76 lists five GPU tiers, and the gap between them is almost entirely about how much a single card holds before that split becomes necessary:

GPU option	Memory	Configuration
Nvidia A400	4GB	Single card, base config
AMD Radeon AI Pro R9700	32GB or 64GB	Single or dual
Nvidia RTX Pro 4000	24GB or 48GB	Single or dual
Nvidia RTX Pro 5000	48GB or 96GB	Single or dual
Nvidia RTX Pro 6000	96GB or 192GB	Single or dual

The RAM ceiling moves independently: up to 192GB of DDR5 at 3,600 megahertz across four 48GB modules, System76 said, which matters for preprocessing and for models offloaded partly to system memory rather than GPU memory.

What ships in the box that a self-built machine would not

The Thelio Mira AI ships with a choice of Pop!_OS 24.04 LTS running System76's own COSMIC desktop, or Ubuntu 24.04 or 26.04 LTS, according to the product page. System76 also lists one, two or three-year parts-and-labor warranty tiers plus lifetime technical support, a commitment a self-assembled workstation running the same AMD and Nvidia parts would not carry.

Storage tops out at two additional M.2 slots for up to 8TB combined and two 2.5-inch bays for up to 16TB more, on top of the 1TB, 2TB or 4TB Gen5 boot drive, System76 said.

What would change this read

System76 published no benchmark figures with the launch, on any of the five GPU tiers, at any batch size or precision. Every comparison in this piece is a spec-sheet comparison, not a measured one. If System76 or an independent reviewer later publishes tokens-per-second figures at a given batch size and context length, that would let a buyer compare the $3,299 entry card against the AMD Radeon AI Pro R9700 tier directly rather than by memory alone, which is what a workstation like Intel's Crescent Island was criticized for omitting at its own launch.

For a buyer choosing between a single powerful GPU and cheaper compute assembled at home, the comparison that matters is the one System76 has not published: what a $998 training run like the one described in a recent from-scratch small-model project would cost in wall-clock time on the base A400 configuration versus the dual RTX Pro 6000 tier, 136 times the price.
