Radeon RX 7700 XT vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7700 XT vs Arc A770
The Radeon RX 7700 XT is dramatically faster, around 60% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 7700 XT is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
Pricing has the Arc A770 at $555 AUD, $308 AUD under the Radeon RX 7700 XT's $863 AUD. Because it's both faster and competitively priced, the Radeon RX 7700 XT wins on performance-per-dollar. The Arc A770 still sits about $226 AUD above its $329 AUD MSRP. The Radeon RX 7700 XT still sits about $414 AUD above its $449 AUD MSRP.
Power & Efficiency
At 225W vs 245W, the Arc A770 is the gentler load on your system. The Radeon RX 7700 XT'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 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Arc A770 carries 16GB versus 12GB on the Radeon RX 7700 XT. 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 A770 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 A770 or Radeon RX 7700 XT?
The Radeon RX 7700 XT 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.
