Radeon RX 6600 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX 6600 vs GeForce GTX 1660 SUPER
The Radeon RX 6600 is significantly faster, around 36% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX 6600 is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Price & Value
The GeForce GTX 1660 SUPER currently lists from $157 BRL, $1,713 BRL less than the Radeon RX 6600 at $1,870 BRL. Despite being slower, the GeForce GTX 1660 SUPER offers the better performance-per-dollar (~775% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 SUPER is trading below its $229 BRL MSRP — a genuine deal. The Radeon RX 6600 still sits about $1,540 BRL above its $330 BRL MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 SUPER is the gentler choice at 125W versus 132W. The Radeon RX 6600 is more efficient per watt because it's faster, but its higher 132W draw means more heat and a bigger PSU. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 6600 carries 8GB versus 6GB on the GeForce GTX 1660 SUPER. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Radeon RX 6600 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 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?
Choose the Radeon RX 6600 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 SUPER stretches your money further for only slightly lower performance.
