Radeon RX 7900 GRE vs Arc B580: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs Arc B580
The Radeon RX 7900 GRE is dramatically faster, around 95% ahead of the Arc B580. That gap is enough to move it up a tier: the Radeon RX 7900 GRE 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 $1,262 AED, $5,217 AED less than the Radeon RX 7900 GRE at $6,479 AED. Despite being slower, the Arc B580 offers the better performance-per-dollar (~163% better value), so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $1,014 AED above its $248 AED MSRP. The Radeon RX 7900 GRE still sits about $5,930 AED above its $549 AED MSRP.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 260W. The Radeon RX 7900 GRE is more efficient per watt because it's faster, but its higher 260W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 7900 GRE 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 7900 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 7900 GRE?
Choose the Radeon RX 7900 GRE 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.
