Radeon RX 6900 XT vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 6900 XT vs Arc A770
The Radeon RX 6900 XT is dramatically faster, around 100% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 6900 XT is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
Right now the Arc A770 starts at $2,126 AED against $3,064 AED for the Radeon RX 6900 XT. Because it's both faster and competitively priced, the Radeon RX 6900 XT wins on performance-per-dollar by about 39%. The Arc A770 still sits about $1,797 AED above its $329 AED MSRP. The Radeon RX 6900 XT still sits about $2,065 AED above its $999 AED MSRP.
Power & Efficiency
The Arc A770 is the lighter draw at 225W against the Radeon RX 6900 XT's 300W, making it the easier card to power and cool. The Radeon RX 6900 XT draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route.
Generation & Longevity
The Arc A770 is roughly 2 years newer than the Radeon RX 6900 XT (Alchemist vs RDNA 2), 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 6900 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 6900 XT?
The Radeon RX 6900 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.
