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 — Arc B580
Intel finally got graphics right. The B580 is genuinely competitive on price/performance and 12 GB helps it age. Drivers are much improved but occasional oddity remains.
