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 GTX 780 Ti GPU
The NVIDIA GeForce GTX 780 Ti is an end-of-life desktop graphics card that released in Q4 2013 with a MSRP of $699. It is built on the Kepler GPU microarchitecture (codename GK110B) and is manufactured on a 28 nm process.
Memory
The GTX 780 Ti has 3 GB of GDDR5 memory, with a 1,753 MHz memory clock and a 384 bit interface. This gives it a memory bandwidth of 336.6 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 780 Ti includes 2,880 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 875 MHz and can dynamically boost its clock speed up to 928 MHz. Complementing the processing units are 240 texture mapping units (TMUs) for efficient texture filtering and 48 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 780 Ti occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 600 W to handle the GPU's thermal design power (TDP) of 250 W.
Benchmark Performance & Value
The GTX 780 Ti has the 141st best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 14.93% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 15,619 score and $699 launch price (MSRP) gives it a performance per dollar of 22.34. This is the 83rd best in value for the 3DMark 11 Performance GPU benchmark.
