GeForce RTX 5090 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5090 vs Arc B580
The GeForce RTX 5090 is dramatically faster, around 317% 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.
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 GeForce RTX 5090 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Arc B580 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 5090 or Arc B580?
The GeForce RTX 5090 is the faster card by about 317%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
