Radeon RX 9070 GRE vs Radeon RX 6800 XT: In-Depth Breakdown
Performance: Radeon RX 9070 GRE vs Radeon RX 6800 XT
The Radeon RX 6800 XT and Radeon RX 9070 GRE post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to 1440p gaming.
Price & Value
The Radeon RX 6800 XT currently lists from $460 GBP, $40 GBP less than the Radeon RX 9070 GRE at $500 GBP. Despite being slower, the Radeon RX 6800 XT offers the better performance-per-dollar (~6% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6800 XT is trading below its $649 GBP MSRP — a genuine deal. The Radeon RX 9070 GRE is trading below its $549 GBP MSRP — a genuine deal.
Power & Efficiency
At 220W against 300W, the Radeon RX 9070 GRE is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern RDNA 4 architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Radeon RX 6800 XT at 16GB versus 12GB on the Radeon RX 9070 GRE — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The Radeon RX 6800 XT's memory is also faster — 512 GB/s versus 432 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 9070 GRE is roughly 6 years newer than the Radeon RX 6800 XT (RDNA 4 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 9070 GRE?
Choose the Radeon RX 9070 GRE if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6800 XT stretches your money further for near-identical performance.
