Radeon RX 7900 GRE vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs Arc A770
The Radeon RX 7900 GRE is dramatically faster, around 115% ahead of the Arc A770. 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 A770 is better matched to 1080p.
Price & Value
The Arc A770 currently lists from $1,561 AED, $4,917 AED less than the Radeon RX 7900 GRE at $6,479 AED. Despite being slower, the Arc A770 offers the better performance-per-dollar (~93% better value), so budget-focused buyers should weigh it carefully. The Arc A770 still sits about $1,232 AED above its $329 AED MSRP. The Radeon RX 7900 GRE still sits about $5,930 AED above its $549 AED MSRP.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W 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. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
Generation & Longevity
The Radeon RX 7900 GRE is roughly 2 years newer than the Arc A770 (RDNA 3 vs Alchemist), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A770 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 A770 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 A770 stretches your money further for only slightly lower performance.
