Radeon RX 5700 vs Radeon RX 6600: In-Depth Breakdown
Performance: Radeon RX 5700 vs Radeon RX 6600
The Radeon RX 5700 and Radeon RX 6600 post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 1080p gaming. The Radeon RX 5700 packs 2,304 stream processors versus 1,792 on the Radeon RX 6600.
Power & Efficiency
At 132W against 180W, the Radeon RX 6600 is both the lower-power and the more efficient card, making it the easier build to cool and power. 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 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 (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 or Radeon RX 6600?
The Radeon RX 5700 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.
