Verdict — RX 7900 XTX
Aging well for pure rasterization but the RT gap kept it out of the mainstream conversation. Great on the used market for raster-focused workloads.
Verdict — RX 7800 XT
Best price-per-frame at 1440p for its generation. FSR is workable, RT is passable but not why you'd buy it. Very popular pick with informed budget builders.
