Radeon RX 7800 XT vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 7800 XT vs Arc B580
The Radeon RX 7800 XT is dramatically faster, around 68% ahead of the Arc B580. That gap is enough to move it up a tier: the Radeon RX 7800 XT is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $344 EUR against $643 EUR for the Radeon RX 7800 XT. Despite being slower, the Arc B580 offers the better performance-per-dollar (~11% better value), so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $96 EUR above its $248 EUR MSRP. The Radeon RX 7800 XT still sits about $144 EUR above its $499 EUR MSRP.
Power & Efficiency
The Arc B580 pulls less power (190W vs 263W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7800 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 12GB, the Radeon RX 7800 XT 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 Radeon RX 7800 XT offers AMD FSR upscaling and strong rasterization value. 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 Radeon RX 7800 XT?
Choose the Radeon RX 7800 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc B580 stretches your money further for only slightly lower performance.
