NVIDIA GeForce RTX 4090 vs Intel Arc B580
Head-to-head comparison: specs, benchmarks, ray tracing, and value. Which is right for your build?
NVIDIA GeForce RTX 4090
Still a beast in 2026. The RTX 4090 remains a genuine 4K monster, especially with DLSS 3 frame generation. It misses out on DLSS 4's multi-frame gen exclusive features, but raw rasterization is still elite. With prices fluctuating since the 5090 launch, it can occasionally be found at attractive discounts.

Intel Arc B580
The shocking value pick of the budget tier. 12GB of VRAM at $249 is unheard of, and Intel's drivers have matured significantly. XeSS 2 with frame generation is competitive. The catch: only worth it on a system with Resizable BAR and a modern CPU.
