About the NVIDIA GeForce GT 620M GPU
The NVIDIA GeForce GT 620M is an end-of-life mobile graphics card that released in Q3 2012. It is built on the Fermi GPU microarchitecture (codename GF108) and is manufactured on a 40 nm process.
Memory
The GT 620M 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 620M includes 96 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 625 MHz and can dynamically boost its clock speed up to 715 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 15 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 620M has the 465th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 0.89% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the NVIDIA GeForce GT 445M GPU
The NVIDIA GeForce GT 445M is an end-of-life mobile graphics card that released in Q3 2010. It is built on the Fermi GPU microarchitecture (codename GF106) and is manufactured on a 40 nm process.
Memory
The GT 445M has 3 GB of DDR3 memory, with a 800 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 38.4 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 445M includes 144 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 590 MHz. Complementing the processing units are 24 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 35 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.
Benchmark Performance
The GT 445M has the 439th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.10% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
