AMD Radeon RX 7900 XT 20GB

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. Neither approach has a published fit or speed result. Flash-Next remains a separate host-offload research path.
