Radeon RX 6800 vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 6800 vs Arc A770
The Radeon RX 6800 is dramatically faster, around 55% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 6800 is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
Right now the Arc A770 starts at $3,102 BRL against $4,676 BRL for the Radeon RX 6800. Because it's both faster and competitively priced, the Radeon RX 6800 wins on performance-per-dollar. The Arc A770 still sits about $2,773 BRL above its $329 BRL MSRP. The Radeon RX 6800 still sits about $4,097 BRL above its $579 BRL MSRP.
Power & Efficiency
The Arc A770 pulls less power (225W vs 250W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6800 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 6800 (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 6800 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 6800?
The Radeon RX 6800 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.
