About the NVIDIA GeForce GT 645M GPU

The NVIDIA GeForce GT 645M is an end-of-life mobile graphics card that released in Q4 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.

Memory

The GT 645M has 2 GB 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 645M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 709 MHz and can dynamically boost its clock speed up to 780 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 32 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GT 645M has the 372nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.76% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce GTX 570M GPU

The NVIDIA GeForce GTX 570M is an end-of-life mobile graphics card that released in Q2 2011. It is built on the Fermi 2.0 GPU microarchitecture (codename GF114) and is manufactured on a 40 nm process.

Memory

The GTX 570M has 1,536 MB of GDDR5 memory, with a 750 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 72 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 570M includes 336 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 575 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 75 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GTX 570M has the 333rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 2.29% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
