Radeon RX 6800 vs Radeon RX 6600: In-Depth Breakdown

Performance: Radeon RX 6800 vs Radeon RX 6600

The Radeon RX 6800 is dramatically faster, around 94% ahead of the Radeon RX 6600. That gap is enough to move it up a tier: the Radeon RX 6800 is comfortable at 1440p, while the Radeon RX 6600 is better matched to 1080p. The Radeon RX 6800 packs 3,840 stream processors versus 1,792 on the Radeon RX 6600. The Radeon RX 6800 also has more RT cores (60 vs 28), strengthening its ray-tracing and AI-upscaling performance.

Price & Value

The Radeon RX 6600 currently lists from $550 GBP, $349 GBP less than the Radeon RX 6800 at $899 GBP. Because it's both faster and competitively priced, the Radeon RX 6800 wins on performance-per-dollar by about 19%. The Radeon RX 6600 still sits about $220 GBP above its $330 GBP MSRP. The Radeon RX 6800 still sits about $320 GBP above its $579 GBP MSRP.

Power & Efficiency

On power, the Radeon RX 6600 is the gentler choice at 132W versus 250W. The Radeon RX 6800 is more efficient per watt because it's faster, but its higher 250W draw means more heat and a bigger PSU.

VRAM & Future-Proofing

The Radeon RX 6800 carries 16GB versus 8GB on the Radeon RX 6600. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon RX 6800's memory is also faster β€” 512 GB/s versus 224 GB/s (256-bit vs 128-bit bus) β€” which helps feed the GPU at 4K and with heavy textures.

Which should you buy: Radeon RX 6600 or Radeon RX 6800?

The Radeon RX 6800 is the all-round winner here β€” it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6600 if you find it at a steep discount.

Frequently Asked Questions

Is the Radeon RX 6800 better than the Radeon RX 6600?

The Radeon RX 6800 is dramatically faster, roughly 94% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the Radeon RX 6600 or the Radeon RX 6800?

Neither is a dedicated 4K card; both are best at 1440p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the Radeon RX 6800 worth the extra $349 GBP over the Radeon RX 6600?

Often yes β€” despite the higher price the Radeon RX 6800 delivers better performance-per-dollar here.

Does the Radeon RX 6800 have enough VRAM advantage to matter?

Its 16GB (vs 8GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.

Which is better for ray tracing, the Radeon RX 6800 or the Radeon RX 6600?

Both handle ray tracing, but the Radeon RX 6800 has more RT cores, giving it better ray-tracing and AI-upscaling performance than the Radeon RX 6600.
