Radeon RX 6600 XT vs Radeon RX 5700: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs Radeon RX 5700
The Radeon RX 6600 XT is noticeably faster, around 18% ahead of the Radeon RX 5700. Both cards sit in the same broad class, well suited to 1080p.
Power & Efficiency
The Radeon RX 6600 XT draws just 160W versus 180W for the Radeon RX 5700, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
Memory & Bandwidth
The Radeon RX 5700's memory is faster — 448 GB/s versus 256 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 6600 XT is roughly 2 years newer than the Radeon RX 5700 (RDNA 2 vs RDNA), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 6600 XT or Radeon RX 5700?
