Radeon RX 5700 XT vs Radeon RX 6600: In-Depth Breakdown
Performance: Radeon RX 5700 XT vs Radeon RX 6600
The Radeon RX 5700 XT is significantly faster, around 20% ahead of the Radeon RX 6600. Both cards sit in the same broad class, well suited to 1080p. The Radeon RX 5700 XT packs 2,560 stream processors versus 1,792 on the Radeon RX 6600.
Power & Efficiency
The Radeon RX 6600 draws just 132W versus 225W for the Radeon RX 5700 XT, 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 XT's memory is faster — 448 GB/s versus 224 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 is roughly 2 years newer than the Radeon RX 5700 XT (RDNA 2 vs RDNA), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 5700 XT or Radeon RX 6600?
The Radeon RX 5700 XT is the faster card by about 20%. 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.
