Radeon RX 6800 XT vs Radeon RX 7800 XT: In-Depth Breakdown
Performance: Radeon RX 6800 XT vs Radeon RX 7800 XT
The Radeon RX 6800 XT and Radeon RX 7800 XT post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 1440p gaming. The Radeon RX 6800 XT packs 4,608 stream processors versus 3,840 on the Radeon RX 7800 XT.
Power & Efficiency
The Radeon RX 7800 XT draws just 263W versus 300W for the Radeon RX 6800 XT, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
Memory & Bandwidth
The Radeon RX 7800 XT's memory is faster — 624 GB/s versus 512 GB/s — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 7800 XT is roughly 3 years newer than the Radeon RX 6800 XT (RDNA 3 vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 6800 XT or Radeon RX 7800 XT?
The Radeon RX 6800 XT 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.
