About the NVIDIA GeForce GTX 1660 Ti Mobile GPU

The NVIDIA GeForce GTX 1660 Ti Mobile is a mobile graphics card that launched in Q2 2019. It is built on the Turing GPU microarchitecture (codename TU116) and is manufactured on a 12 nm process.

Memory

The GTX 1660 Ti Mobile 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 Mobile includes 1,536 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,455 MHz and can dynamically boost its clock speed up to 1,590 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 GPU has a thermal design power (TDP) of 80 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GTX 1660 Ti Mobile has the 110th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 19.23% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce GT 640M LE GPU

The NVIDIA GeForce GT 640M LE is an end-of-life mobile graphics card that released in Q1 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.

Memory

The GT 640M LE has 1,024 MB of DDR3 memory, with a 900 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 28.8 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 GT 640M LE includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 500 MHz and can dynamically boost its clock speed up to 570 MHz. Complementing the processing units are 32 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 20 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GT 640M LE has the 428th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.20% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
