Radeon RX 7900 XT vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7900 XT vs Arc A770
The Radeon RX 7900 XT is dramatically faster, around 150% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 7900 XT is comfortable at 4K with upscaling and native 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
The Radeon RX 7900 XT currently lists from $7,607 SEK, $2,250 SEK less than the Arc A770 at $9,857 SEK. Because it's both faster and competitively priced, the Radeon RX 7900 XT wins on performance-per-dollar by about 224%. The Radeon RX 7900 XT still sits about $6,708 SEK above its $899 SEK MSRP. The Arc A770 still sits about $9,528 SEK above its $329 SEK MSRP.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W versus 300W. The Radeon RX 7900 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 7900 XT carries 20GB versus 16GB on the Arc A770. 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 7900 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 7900 XT?
The Radeon RX 7900 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.
