Radeon RX 6600 XT vs GeForce GTX 1080 Ti: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs GeForce GTX 1080 Ti
The Radeon RX 6600 XT is marginally faster, around 6% ahead of the GeForce GTX 1080 Ti. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Radeon RX 6600 XT starts at $3,135 BRL against $3,360 BRL for the GeForce GTX 1080 Ti. Because it's both faster and competitively priced, the Radeon RX 6600 XT wins on performance-per-dollar by about 13%. The Radeon RX 6600 XT still sits about $2,756 BRL above its $379 BRL MSRP. The GeForce GTX 1080 Ti still sits about $2,661 BRL above its $699 BRL MSRP.
Power & Efficiency
The Radeon RX 6600 XT draws just 160W versus 250W for the GeForce GTX 1080 Ti, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 11GB against 8GB, the GeForce GTX 1080 Ti has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600 XT's 8GB can fall short.
Generation & Longevity
The Radeon RX 6600 XT is roughly 4 years newer than the GeForce GTX 1080 Ti (RDNA 2 vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1080 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6600 XT offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce GTX 1080 Ti or Radeon RX 6600 XT?
The Radeon RX 6600 XT is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 1080 Ti if you find it at a steep discount.
