Radeon RX 7900 XTX vs Radeon RX 6800: In-Depth Breakdown
Performance: Radeon RX 7900 XTX vs Radeon RX 6800
The Radeon RX 7900 XTX is dramatically faster, around 81% ahead of the Radeon RX 6800. That gap is enough to move it up a tier: the Radeon RX 7900 XTX is comfortable at 4K with upscaling and native 1440p, while the Radeon RX 6800 is better matched to 1440p. The Radeon RX 7900 XTX packs 6,144 stream processors versus 3,840 on the Radeon RX 6800.
Price & Value
Right now the Radeon RX 7900 XTX starts at $180 BRL against $4,676 BRL for the Radeon RX 6800. Because it's both faster and competitively priced, the Radeon RX 7900 XTX wins on performance-per-dollar by about 4605%. The Radeon RX 7900 XTX is trading below its $999 BRL MSRP — a genuine deal. The Radeon RX 6800 still sits about $4,097 BRL above its $579 BRL MSRP.
Power & Efficiency
The Radeon RX 6800 pulls less power (250W vs 355W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7900 XTX draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 16GB, the Radeon RX 7900 XTX has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6800's 16GB can fall short. The Radeon RX 7900 XTX's memory is also faster — 960 GB/s versus 512 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 7900 XTX is roughly 2 years newer than the Radeon RX 6800 (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 or Radeon RX 7900 XTX?
The Radeon RX 7900 XTX is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6800 if you find it at a steep discount.
