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 RTX A2000 Mobile GPU
The NVIDIA RTX A2000 Mobile is a mobile graphics card that launched in Q2 2021. It is built on the Ampere GPU microarchitecture (codename GA106) and is manufactured on a 8 nm process.
Memory
The RTX A2000 Mobile has 4 GB of GDDR6 memory, with a 1,500 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 192 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 RTX A2000 Mobile includes 2,560 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,215 MHz and can dynamically boost its clock speed up to 1,687 MHz. Complementing the processing units are 80 texture mapping units (TMUs) for efficient texture filtering and 48 render output units (ROPs) for pixel processing. Additionally, the GPU features 80 tensor cores optimized for AI-accelerated workloads and 20 RT cores dedicated to real-time ray tracing calculations.
Compatibility & Power Consumption
The GPU has a thermal design power (TDP) of 95 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The RTX A2000 Mobile has the 120th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 17.26% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
