## Content

The RX 7900 XT has 20 GB of GDDR6 memory. Its proposed Qwen3.8-27B UD-IQ4_XS recipe uses a compact conversion and 16K catalog context, distinct from the XTX's Q4 32K candidate. The practical question is whether the exact file, context and desktop memory load produce useful answers and latency on this card; the nominal weight size cannot settle that.

For two XTs, a Q8 model split across cards is a capacity experiment, while two IQ4 workers would handle independent jobs. A pair needs slot, negotiated PCIe-link, power and cooling checks. Bitworks has not yet qualified either exact recipe or published its own fit or speed measurements; external reports below use other configurations. Flash-Next remains a separate host-offload research path.
