Radeon RX 6600 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: Radeon RX 6600 vs GeForce GTX 1660 Ti
The Radeon RX 6600 is significantly faster, around 36% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the Radeon RX 6600 is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p.
Price & Value
Pricing has the GeForce GTX 1660 Ti at $190 CAD, $138 CAD under the Radeon RX 6600's $328 CAD. Despite being slower, the GeForce GTX 1660 Ti offers the better performance-per-dollar (~27% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 Ti is trading below its $279 CAD MSRP — a genuine deal.
Power & Efficiency
At 120W vs 132W, the GeForce GTX 1660 Ti is the gentler load on your system. The Radeon RX 6600's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the 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
The Radeon RX 6600 carries 8GB versus 6GB on the GeForce GTX 1660 Ti. 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 Ti (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 Ti 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 Ti 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 Ti stretches your money further for only slightly lower performance.
