Radeon RX 6600 XT vs GeForce GTX 1080: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs GeForce GTX 1080
The Radeon RX 6600 XT is significantly faster, around 38% ahead of the GeForce GTX 1080. That gap is enough to move it up a tier: the Radeon RX 6600 XT is comfortable at 1080p, while the GeForce GTX 1080 is better matched to entry-level 1080p.
Price & Value
Right now the GeForce GTX 1080 starts at $616 SGD against $755 SGD for the Radeon RX 6600 XT. 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 $376 SGD above its $379 SGD MSRP.
Power & Efficiency
The Radeon RX 6600 XT sips power at 160W next to the GeForce GTX 1080's 180W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
Generation & Longevity
The Radeon RX 6600 XT is roughly 5 years newer than the GeForce GTX 1080 (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 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 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 if you find it at a steep discount.
