The Radeon RX 7900 XTX is dramatically faster, around 133% ahead of the Radeon RX 6700 XT. 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 6700 XT is better matched to 1080p. The Radeon RX 7900 XTX packs 6,144 stream processors versus 2,560 on the Radeon RX 6700 XT.
Price & Value
Right now the Radeon RX 7900 XTX starts at $180 BRL against $8,990 BRL for the Radeon RX 6700 XT. Because it's both faster and competitively priced, the Radeon RX 7900 XTX wins on performance-per-dollar by about 11584%. The Radeon RX 7900 XTX is trading below its $999 BRL MSRP — a genuine deal. The Radeon RX 6700 XT still sits about $8,511 BRL above its $479 BRL MSRP.
Power & Efficiency
The Radeon RX 6700 XT pulls less power (230W 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 12GB, the Radeon RX 7900 XTX has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6700 XT's 12GB can fall short. The Radeon RX 7900 XTX's memory is also faster — 960 GB/s versus 384 GB/s (384-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 6700 XT 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 6700 XT if you find it at a steep discount.
