NVIDIA GeForce GTX 1660 Ti vs AMD Radeon HD 6450

The NVIDIA GeForce GTX 1660 Ti is a desktop graphics card that launched in Q1 2019 with a MSRP of $279. It is built on the Turing GPU microarchitecture (codename TU116) and is manufactured on a 12 nm process.

Memory

The GTX 1660 Ti has 6 GB of GDDR6 memory, with a 1,500 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 288 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The GTX 1660 Ti includes 1,536 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,500 MHz and can dynamically boost its clock speed up to 1,770 MHz. Complementing the processing units are 96 texture mapping units (TMUs) for efficient texture filtering and 48 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GTX 1660 Ti occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0, DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 120 W.

Benchmark Performance & Value

The GTX 1660 Ti has the 103rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 21.89% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 22,891.5 score and $279 launch price (MSRP) gives it a performance per dollar of 82.05. This is the 35th best in value for the 3DMark 11 Performance GPU benchmark.
