GeForce RTX 5070 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5070 vs Arc B580
The GeForce RTX 5070 is dramatically faster, around 96% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 5070 is comfortable at 4K with upscaling and native 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $289 GBP against $539 GBP for the GeForce RTX 5070. Because it's both faster and competitively priced, the GeForce RTX 5070 wins on performance-per-dollar by about 5%.
Power & Efficiency
The Arc B580 pulls less power (190W vs 250W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5070 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.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 5070 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 5070 or Arc B580?
The GeForce RTX 5070 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.
