The Arc B580 still sits about $152 above its $248 MSRP. The Radeon RX 6600 still sits about $628 above its $330 MSRP.
Power & Efficiency
The Radeon RX 6600 draws just 132W versus 190W for the Arc B580, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 12GB against 8GB, the Arc B580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600's 8GB can fall short.
Generation & Longevity
The Arc B580 is roughly 3 years newer than the Radeon RX 6600, so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Radeon RX 6600 brings AMD FSR upscaling and strong rasterization value, while the Arc B580 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Radeon RX 6600 or Arc B580?
the Arc B580 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 6600 if you find it at a steep discount.
