GeForce RTX 5090 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5090 vs Arc B580
The GeForce RTX 5090 is dramatically faster, around 355% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 5090 is comfortable at 4K and high-refresh 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $341 EUR against $816 EUR for the GeForce RTX 5090. Because it's both faster and competitively priced, the GeForce RTX 5090 wins on performance-per-dollar by about 90%. The Arc B580 still sits about $93 EUR above its $248 EUR MSRP. The GeForce RTX 5090 is trading below its $1,999 EUR MSRP — a genuine deal.
Power & Efficiency
The Arc B580 pulls less power (190W vs 575W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5090 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
With 32GB against 12GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc B580's 12GB can fall short.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 5090 offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Arc B580 or GeForce RTX 5090?
The GeForce RTX 5090 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Arc B580 if you find it at a steep discount.
