RX 6800 XT vs RX 9060 XT for ComfyUI: is the $105 premium worth it for LTX and Wan?
Nice-Regret-9207 · reddit · 2026-09-03
A Reddit user on an RX 6750 XT 12GB (Windows, PatientX ROCm) is deciding between an RX 6800 XT 16GB ($380) and an RX 9060 XT 16GB ($485) — a $105–110 gap.
Current real-world numbers on the 6750 XT:
- LTX 2.3 22B distilled Q4KM GGUF, 480p 5s video: 305–380s
- Wan 2.2 rapid i2v/t2v at 432x736: 380–420s
Workloads are LTX 2.3, Wan 2.2, and ComfyUI image gen (Flux/SD/zturbo). The poster asks for actual generation-time benchmarks rather than gaming scores: does the 9060 XT's newer architecture win, or do the 6800 XT's raw compute, memory bandwidth and 16GB VRAM make it the better AI buy?
