NVIDIA GeForce RTX 5090 vs Intel Arc B580
Head-to-head comparison: specs, benchmarks, ray tracing, and value. Which is right for your build?
NVIDIA GeForce RTX 5090
The undisputed king of consumer GPUs. The RTX 5090 delivers untouchable 4K performance, dominates ray tracing with 4th-gen RT cores, and runs DLSS 4 with multi-frame generation. With 32GB of GDDR7, it's also a beast for AI and content creation workloads. The catch: $1999 MSRP, 575W TDP, and you'll need a 1000W PSU minimum.

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.
