Radeon RX 9070 GRE vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 9070 GRE vs Arc B580
The Radeon RX 9070 GRE is dramatically faster, around 73% ahead of the Arc B580. That gap is enough to move it up a tier: the Radeon RX 9070 GRE is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Pricing has the Arc B580 at $56,800 JPY, $38,000 JPY under the Radeon RX 9070 GRE's $94,800 JPY. Because it's both faster and competitively priced, the Radeon RX 9070 GRE wins on performance-per-dollar. The Arc B580 still sits about $56,552 JPY above its $248 JPY MSRP. The Radeon RX 9070 GRE still sits about $94,251 JPY above its $549 JPY MSRP.
Power & Efficiency
At 190W vs 220W, the Arc B580 is the gentler load on your system. The Radeon RX 9070 GRE's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom. Its more modern RDNA 4 architecture on a TSMC N4 process is part of why it does more with each watt.
Generation & Longevity
The Radeon RX 9070 GRE is roughly 2 years newer than the Arc B580 (RDNA 4 vs Battlemage), 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 9070 GRE 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 GRE?
The Radeon RX 9070 GRE 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.
