Radeon RX 7900 XTX vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7900 XTX vs Arc A770
The Radeon RX 7900 XTX is dramatically faster, around 180% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 7900 XTX 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 $74,931 INR, $115,675 INR less than the Radeon RX 7900 XTX at $190,606 INR. Because it's both faster and competitively priced, the Radeon RX 7900 XTX wins on performance-per-dollar by about 10%. The Arc A770 still sits about $74,602 INR above its $329 INR MSRP. The Radeon RX 7900 XTX still sits about $189,607 INR above its $999 INR MSRP.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W versus 355W. The Radeon RX 7900 XTX is more efficient per watt because it's faster, but its higher 355W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 7900 XTX carries 24GB versus 16GB on the Arc A770. The extra 8GB 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 XTX 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 XTX?
The Radeon RX 7900 XTX 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.
