Arc B580 vs Radeon RX 5700 XT: In-Depth Breakdown
Performance: Arc B580 vs Radeon RX 5700 XT
The Arc B580 is significantly faster, around 22% ahead of the Radeon RX 5700 XT. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
The Radeon RX 5700 XT currently lists from $295 CAD, $65 CAD less than the Arc B580 at $360 CAD. Because it's both faster and competitively priced, the Arc B580 wins on performance-per-dollar. The Radeon RX 5700 XT is trading below its $399 CAD MSRP — a genuine deal. The Arc B580 still sits about $112 CAD above its $248 CAD MSRP.
Power & Efficiency
At 190W against 225W, the Arc B580 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Arc B580 at 12GB versus 8GB on the Radeon RX 5700 XT — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Arc B580 is roughly 5 years newer than the Radeon RX 5700 XT (Battlemage vs RDNA), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 5700 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 5700 XT?
The Arc B580 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 5700 XT if you find it at a steep discount.
