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.
About the NVIDIA GeForce GTX 950 GPU
The NVIDIA GeForce GTX 950 is an end-of-life desktop graphics card that released in Q3 2015 with a MSRP of $159. It is built on the Maxwell 2.0 GPU microarchitecture (codename GM206) and is manufactured on a 28 nm process.
Memory
The GTX 950 has 2 GB of GDDR5 memory, with a 1,653 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 105.8 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 GTX 950 includes 768 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,024 MHz and can dynamically boost its clock speed up to 1,188 MHz. Complementing the processing units are 48 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 950 occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 90 W.
Benchmark Performance & Value
The GTX 950 has the 199th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 7.98% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 8,351 score and $159 launch price (MSRP) gives it a performance per dollar of 52.52. This is the 63rd best in value for the 3DMark 11 Performance GPU benchmark.
