Radeon RX 6800 XT vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 6800 XT vs Arc A770
The Radeon RX 6800 XT is dramatically faster, around 85% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 6800 XT is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
The Arc A770 currently lists from $3,102 BRL, $6,439 BRL less than the Radeon RX 6800 XT at $9,541 BRL. Despite being slower, the Arc A770 offers the better performance-per-dollar (~66% better value), so budget-focused buyers should weigh it carefully. The Arc A770 still sits about $2,773 BRL above its $329 BRL MSRP. The Radeon RX 6800 XT still sits about $8,892 BRL above its $649 BRL MSRP.
Power & Efficiency
On power, the Arc A770 is the gentler choice at 225W versus 300W. The Radeon RX 6800 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU.
Generation & Longevity
The Arc A770 is roughly 2 years newer than the Radeon RX 6800 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 6800 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 6800 XT?
Choose the Radeon RX 6800 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A770 stretches your money further for only slightly lower performance.
