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 $504 CAD, $101 CAD less than the Radeon RX 7900 GRE at $605 CAD. Because it's both faster and competitively priced, the Radeon RX 7900 GRE wins on performance-per-dollar by about 79%. The Arc A770 still sits about $175 CAD above its $329 CAD 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?
The Radeon RX 7900 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 A770 if you find it at a steep discount.
