Nvidia GeForce RTX 4090
The GeForce RTX 4090 is the flagship graphics card in Nvidia's consumer GPU family, succeeding the GeForce RTX 30 series. It is based on Nvidia's Ada Lovelace architecture and features third-generation RT cores and fourth-generation Tensor Cores for hardware acceleration.
Best for High-end graphics tasks
Pros
- Features a TSMC 4N process designed by Nvidia
- Includes three-generation Ray Tracing Cores for accelerated ray tracing
- Supports OpenGL 4.6, Vulkan 1.4, and DirectX Direct3D 12.0 Ultimate APIs
- Features dual NVENC with 8K 10-bit 120FPS AV1 fixed function hardware encoding
Cons
- No NVLink support
- Double-precision performance is 1/64 of single-precision performance
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
