Radeon RX 7700 XT vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 7700 XT vs Arc B580
The Radeon RX 7700 XT is dramatically faster, around 45% ahead of the Arc B580. That gap is enough to move it up a tier: the Radeon RX 7700 XT is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
The Arc B580 currently lists from $49,789 JPY, $24,665 JPY less than the Radeon RX 7700 XT at $74,454 JPY. 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 $49,541 JPY above its $248 JPY MSRP. The Radeon RX 7700 XT still sits about $74,005 JPY above its $449 JPY MSRP.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 245W. The Radeon RX 7700 XT is more efficient per watt because it's faster, but its higher 245W draw means more heat and a bigger PSU.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 7700 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 7700 XT?
Choose the Radeon RX 7700 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.
