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 $504 CAD against $700 CAD 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 44%. The Arc A770 still sits about $175 CAD above its $329 CAD MSRP. The Radeon RX 6900 XT is trading below its $999 CAD MSRP — a genuine deal.

Power & Efficiency

The Arc A770 pulls less power (225W vs 300W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6900 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.

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.
