Arc A770 vs Radeon RX Vega 64: In-Depth Breakdown
Performance: Arc A770 vs Radeon RX Vega 64
The Arc A770 is dramatically faster, around 43% ahead of the Radeon RX Vega 64. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Arc A770 starts at $504 CAD against $650 CAD for the Radeon RX Vega 64. Because it's both faster and competitively priced, the Arc A770 wins on performance-per-dollar by about 84%. The Arc A770 still sits about $175 CAD above its $329 CAD MSRP. The Radeon RX Vega 64 still sits about $151 CAD above its $499 CAD MSRP.
Power & Efficiency
The Arc A770 draws just 225W versus 295W for the Radeon RX Vega 64, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 8GB, the Arc A770 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX Vega 64's 8GB can fall short.
Generation & Longevity
The Arc A770 is roughly 5 years newer than the Radeon RX Vega 64 (Alchemist vs GCN 5.0 (Vega)), 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 Vega 64 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 Vega 64?
The Arc A770 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX Vega 64 if you find it at a steep discount.
