Radeon RX 6800 vs Radeon RX 6600 XT: In-Depth Breakdown
Performance: Radeon RX 6800 vs Radeon RX 6600 XT
The Radeon RX 6800 is dramatically faster, around 72% ahead of the Radeon RX 6600 XT. That gap is enough to move it up a tier: the Radeon RX 6800 is comfortable at 1440p, while the Radeon RX 6600 XT is better matched to 1080p. The Radeon RX 6800 packs 3,840 stream processors versus 2,048 on the Radeon RX 6600 XT. The Radeon RX 6800 also has more RT cores (60 vs 32), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the Radeon RX 6600 XT starts at $3,135 BRL against $4,675 BRL for the Radeon RX 6800. Because it's both faster and competitively priced, the Radeon RX 6800 wins on performance-per-dollar by about 15%. The Radeon RX 6600 XT still sits about $2,756 BRL above its $379 BRL MSRP. The Radeon RX 6800 still sits about $4,096 BRL above its $579 BRL MSRP.
Power & Efficiency
The Radeon RX 6600 XT pulls less power (160W vs 250W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6800 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 8GB, the Radeon RX 6800 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600 XT's 8GB can fall short. The Radeon RX 6800's memory is also faster — 512 GB/s versus 256 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 6600 XT or Radeon RX 6800?
The Radeon RX 6800 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 6600 XT if you find it at a steep discount.
