Compare two Radeon GPUs
Pick two Radeon GPUs that already have AMDai sheets — R9700, PRO W7900 / W7800 / W7700 / W6800, RX 9070 XT, RX 9060 XT, RX 7900 GRE, RX 7700 XT, RX 7600 XT, RX 7600, RX 6800 XT, RX 6700 XT, and Strix Halo. Each pair page uses VRAM and bandwidth from the existing GPU data, calculator fit for Qwen3.6-35B-A3B on llama.cpp at Q6 / Q5 / Q4 plus a labeled UD-Q3_K_XL estimate, and ROCm notes from the cited gfx rows. Measured tok/s appear only on the R9700 side. We do not invent a price. Minimum system RAM needed and RAM needed at full context print wherever a file spills to system RAM.
Vetting a used listing — gfx, VRAM, Linux identity commands, PSU — is Buying a used Radeon, not a second copy of these pair tables.
How we test — Measured cells cite official amdai-bench/run@1 cards. Estimates stay labeled. Q3 is estimate-only. Q1/Q2 stay off.
