Performance: Arc A770 vs Radeon RX 6600M
The Arc A770 is marginally faster, around 5% ahead of the Radeon RX 6600M. Both cards sit in the same broad class, well suited to 1080p.
Power & Efficiency
At 100W against 225W, the Radeon RX 6600M is both the lower-power and the more efficient card, making it the easier build to cool and power.
VRAM & Future-Proofing
The Arc A770 carries 16GB versus 8GB on the Radeon RX 6600M. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Arc A770 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 6600M 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 6600M?
The Arc A770 is the faster card. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
