Arc B570 vs Radeon RX Vega 64: In-Depth Breakdown
Performance: Arc B570 vs Radeon RX Vega 64
The Arc B570 is significantly faster, around 21% ahead of the Radeon RX Vega 64. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
The Radeon RX Vega 64 currently lists from $150 USD, $90 USD less than the Arc B570 at $240 USD. Despite being slower, the Radeon RX Vega 64 offers the better performance-per-dollar (~32% better value), so budget-focused buyers should weigh it carefully. The Radeon RX Vega 64 is trading below its $499 USD MSRP — a genuine deal.
Power & Efficiency
At 150W against 295W, the Arc B570 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Arc B570 at 10GB versus 8GB on the Radeon RX Vega 64 — that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Arc B570 is roughly 8 years newer than the Radeon RX Vega 64 (Battlemage 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 B570 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 B570 or Radeon RX Vega 64?
Choose the Arc B570 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX Vega 64 stretches your money further for only slightly lower performance.
