Radeon RX 6700 XT vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 6700 XT vs Arc B580
The Radeon RX 6700 XT is noticeably faster, around 9% ahead of the Arc B580. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Arc B580 starts at $28,885 INR against $32,695 INR for the Radeon RX 6700 XT. Despite being slower, the Arc B580 offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $28,637 INR above its $248 INR MSRP. The Radeon RX 6700 XT still sits about $32,216 INR above its $479 INR MSRP.
Power & Efficiency
The Arc B580 sips power at 190W next to the Radeon RX 6700 XT's 230W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
Generation & Longevity
The Arc B580 is roughly 3 years newer than the Radeon RX 6700 XT (Battlemage vs RDNA 2), 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 6700 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 6700 XT?
Choose the Radeon RX 6700 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.
