Best for Professional computingBest for Advanced renderingBest for AI compute
Pros
- Supports GDDR7 video memory
- Uses the Blackwell microarchitecture with high graphics frequencies and large L2 caches
- Features fourth-generation RTX cores for hardware-accelerated real-time ray tracing and fifth-generation Tensor Cores
Nvidia GeForce GTX 1660 Ti
The Nvidia GeForce GTX 1660 Ti is a mid-range graphics card built on Nvidia's Turing architecture using TSMC's 12 nm FinFET manufacturing process. Powered by the TU116-400-A1 graphics chip, it connects via a PCIe 3.0 x16 interface and delivers solid conventional rendering performance. It was designed for budget-conscious gamers by omitting the dedicated hardware Ray Tracing and Tensor cores present in the higher-tier RTX 20 series.
Best for Budget 1080p gaming builds focused on traditional rasterization performanceBest for Upgrading older system builds limited to PCIe 3.0 motherboard slots
Pros
- Leverages the Turing architecture with concurrent execution of integer and floating-point operations
- Manufactured on a 12 nm FinFET process for reliable mid-range performance
- Supports modern graphics APIs including Direct3D 12.0, Vulkan 1.4, and OpenGL 4.6
Cons
- Lacks dedicated hardware RT (ray tracing) and Tensor (AI) cores present in RTX-branded GPUs
- Uses older PCIe 3.0 bus architecture rather than newer interface standards
- Officially discontinued by Nvidia in March 2024, limiting future product support
