About the NVIDIA GeForce GT 645M GPU
The NVIDIA GeForce GT 645M is an end-of-life mobile graphics card that released in Q4 2012. It is built on the Kepler GPU microarchitecture (codename GK107) and is manufactured on a 28 nm process.
Memory
The GT 645M 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 645M includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 709 MHz and can dynamically boost its clock speed up to 780 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 645M has the 372nd best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.76% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
About the NVIDIA GeForce GTX 470 GPU
The NVIDIA GeForce GTX 470 is an end-of-life desktop graphics card that released in Q1 2010 with a MSRP of $349. It is built on the Fermi GPU microarchitecture (codename GF100) and is manufactured on a 40 nm process.
Memory
The GTX 470 has 1,280 MB of GDDR5 memory, with a 837 MHz memory clock and a 320 bit interface. This gives it a memory bandwidth of 133.9 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 470 includes 448 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 607 MHz. Complementing the processing units are 56 texture mapping units (TMUs) for efficient texture filtering and 40 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 470 occupies 2 PCIe expansion slots. It supports DVI, mini-HDMI 1.3a display connections. NVIDIA recommends a power supply of at least 550 W to handle the GPU's thermal design power (TDP) of 215 W.
Benchmark Performance & Value
The GTX 470 has the 266th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 4.15% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090. Its 4,342 score and $349 launch price (MSRP) gives it a performance per dollar of 12.44. This is the 94th best in value for the 3DMark 11 Performance GPU benchmark.
