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
The Radeon RX 6600 currently lists from $1,870 BRL, $547 BRL less than the GeForce GTX 1660 Ti at $2,417 BRL. Because it's both faster and competitively priced, the Radeon RX 6600 wins on performance-per-dollar by about 76%. The Radeon RX 6600 still sits about $1,540 BRL above its $330 BRL MSRP. The GeForce GTX 1660 Ti still sits about $2,138 BRL above its $279 BRL MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 Ti is the gentler choice at 120W 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 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?
The Radeon RX 6600 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 Ti if you find it at a steep discount.
