Radeon RX 7800 XT vs Arc A770: In-Depth Breakdown
Performance: Radeon RX 7800 XT vs Arc A770
The Radeon RX 7800 XT is dramatically faster, around 85% ahead of the Arc A770. That gap is enough to move it up a tier: the Radeon RX 7800 XT is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
On price, expect to pay $160 USD for the Arc A770 versus $718 USD for the Radeon RX 7800 XT. Despite being slower, the Arc A770 offers the better performance-per-dollar (~143% better value), so budget-focused buyers should weigh it carefully. The Arc A770 is trading below its $329 USD MSRP — a genuine deal. The Radeon RX 7800 XT still sits about $219 USD above its $499 USD MSRP.
Power & Efficiency
The Arc A770 pulls less power (225W vs 263W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7800 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
Features & Ecosystem
Beyond raw numbers, the Arc A770 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 7800 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 7800 XT?
Choose the Radeon RX 7800 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.
