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
The Arc A770 currently lists from $3,102 BRL, $1,198 BRL less than the Radeon RX 7700 XT at $4,300 BRL. Because it's both faster and competitively priced, the Radeon RX 7700 XT wins on performance-per-dollar by about 15%. The Arc A770 still sits about $2,773 BRL above its $329 BRL MSRP. The Radeon RX 7700 XT still sits about $3,851 BRL above its $449 BRL MSRP.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W versus 245W. The Radeon RX 7700 XT is more efficient per watt because it's faster, but its higher 245W 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.
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.
