Radeon RX 6600 XT vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs GeForce GTX 1660 SUPER
The Radeon RX 6600 XT is dramatically faster, around 64% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX 6600 XT is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX 6600 XT starts at $5,138 SEK against $6,114 SEK for the GeForce GTX 1660 SUPER. Because it's both faster and competitively priced, the Radeon RX 6600 XT wins on performance-per-dollar by about 95%. The Radeon RX 6600 XT still sits about $4,759 SEK above its $379 SEK MSRP. The GeForce GTX 1660 SUPER still sits about $5,885 SEK above its $229 SEK MSRP.
Power & Efficiency
The GeForce GTX 1660 SUPER pulls less power (125W vs 160W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6600 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. 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 8GB against 6GB, the Radeon RX 6600 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 SUPER's 6GB can fall short.
Generation & Longevity
The Radeon RX 6600 XT is roughly 2 years newer than the GeForce GTX 1660 SUPER (RDNA 2 vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1660 SUPER 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 1660 SUPER 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 1660 SUPER if you find it at a steep discount.
