Radeon RX 9070 XT vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 9070 XT vs Arc B580
The Radeon RX 9070 XT is dramatically faster, around 136% ahead of the Arc B580. That gap is enough to move it up a tier: the Radeon RX 9070 XT is comfortable at 4K with upscaling and native 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
The Arc B580 currently lists from $331 EUR, $375 EUR less than the Radeon RX 9070 XT at $706 EUR. Because it's both faster and competitively priced, the Radeon RX 9070 XT wins on performance-per-dollar by about 11%. The Arc B580 still sits about $83 EUR above its $248 EUR MSRP. The Radeon RX 9070 XT still sits about $107 EUR above its $599 EUR MSRP.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 304W. The Radeon RX 9070 XT is more efficient per watt because it's faster, but its higher 304W draw means more heat and a bigger PSU. Its more modern RDNA 4 architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 9070 XT carries 16GB versus 12GB on the Arc B580. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 9070 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 9070 XT?
The Radeon RX 9070 XT 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.
