Beskrivelse
What it is
The largest configuration in this category. Ryzen AI Max+ PRO 495 with sixteen cores and 32 threads, Radeon 8065S integrated graphics with 40 RDNA 3.5 compute units, and 192 GB of LPDDR5X-8533 unified memory. Up to 160 GB of that memory can be handed to the graphics unit.
The memory is the product. It is soldered, fast and shared: the 160 GB the graphics unit holds is memory the processor stops using while it holds it. One pool, not two — that is what makes models in the 300B class at 4-bit quantisation practical on a desk, and it is also the constraint you plan around.
What it can do
- Load models that need more than 128 GB, including large mixture-of-experts checkpoints at 4-bit.
- Run several agents side by side, each with a separate KV cache and long context.
- Generate video and image batches locally instead of renting a GPU by the hour.
- Fine-tune mid-size models on data that never leaves the machine.
- Serve inference over the network to a small team.
Validated at processor level for Windows 11 64-bit, Ubuntu and RHEL.
What comes with it
- The machine itself, assembled in the configuration described on this page.
- The manufacturer’s power supply and quick-start documentation.
- An invoice from PureDNA, sent by e-mail.
What does not
- Monitor, keyboard, mouse or speakers. It is a desktop machine and needs a screen and mains power.
- An operating system licence. No OS is installed or licensed by PureDNA; the processor vendor validates the platform for Windows 11 64 bit and for current Linux distributions, and you install what you use.
- Extra memory. It is soldered to the board and cannot be expanded or replaced later.
- Storage beyond the capacity confirmed for your unit. The drive size is fixed when an order is placed.
- CUDA. There is no NVIDIA hardware here, so software that only runs on CUDA has to go through ROCm, Vulkan or the processor instead.
