About the NVIDIA GeForce GT 640M GPU

The NVIDIA GeForce GT 640M 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 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 640M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 624 MHz and can dynamically boost its clock speed up to 709 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 640M has the 386th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.65% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

About the NVIDIA GeForce GT 630M GPU

The NVIDIA GeForce GT 630M is an end-of-life mobile graphics card that released in Q1 2012. It is built on the Fermi 2.0 GPU microarchitecture (codename GF117) and is manufactured on a 28 nm process.

Memory

The GT 630M has 1,024 MB of GDDR5 memory, with a 1,000 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 64 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 630M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 800 MHz. Complementing the processing units are 16 texture mapping units (TMUs) for efficient texture filtering and 4 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 33 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The GT 630M has the 453rd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.99% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
