## NPU Hardware on Dankclaw

|

Dankclaw runs an AMD Ryzen AI MAX+ 395 (Strix Halo). The chip integrates an XDNA2 NPU rated at 50 TOPS (vendor spec: "NPU TOPS — Up to 50 TOPS", [amd.com product page](https://www.amd.com/en/products/processors/laptop/ryzen/ai-300-series/amd-ryzen-ai-max-plus-395.html)). It sits beside the Radeon 8060S iGPU and shares the same unified memory pool — 30 GiB exposed to the OS in the 2026-08 reading below; the box presents **121 GiB** today (`free -g` total 121, read 2026-10-18).

## Overview
|
||||
|
||||
vLLM uses CPU RAM and swap space to extend GPU memory capacity. This allows larger models to run on GPUs with limited VRAM. vLLM does not offload model weights to CPU. Instead, vLLM moves KV cache data between GPU and CPU.
|
||||
Stock vLLM offloads **KV pages**, not weights: the scheduler moves KV cache between GPU
|
||||
and CPU. That is the upstream behaviour and it is NOT the whole story on our hosts — the
|
||||
tcclaviger/R4D fork ran a real **weight** offload (`--enable-expert-offload`, tiered
|
||||
expert placement, a pinned host pool per rank), which is how a 147 GiB MoE served from a

||||
246 GiB box: [[RDNA4 MoE Expert Offload VRAM Budget]] and the tcclaviger era row of

|

|

Swapping the checkpoint behind **frank-medium** (Dankserver `:7770`,
|
||||
vllm-radiance TP=2) is a four-step process, and the toolchain below drives all
|
||||
of it. The design goal (2026-09-20, after the MXFP4 → FP8 swap) is that a swap
|
||||
is **one command**: generate a manifest, download it verified, point the
|
||||
quadlet at it, deploy. The entrypoint is quantization-aware, so the only repo
|
||||
change a swap makes is the quadlet's four env vars.
|
||||
**Historical.** frank-medium is a retired endpoint — `:7770` on Dankserver is
|
||||
[[frank-archon]] today, and the live procedure is [[Model Swap and Rollback]].
|
||||
This page records how a swap worked in that era: a four-step process whose design
|
||||
goal (2026-09-20, after the MXFP4 → FP8 swap) was that a swap be **one command** —
|
||||
generate a manifest, download it verified, point the quadlet at it, deploy. The
|
||||
entrypoint was quantization-aware, so the only repo change a swap made was the

quadlet's four env vars.
