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 AMD Radeon R5 M230 GPU
The AMD Radeon R5 M230 is an end-of-life mobile graphics card that released in Q1 2014. It is built on the GCN 1.0 GPU microarchitecture (codename Jet) and is manufactured on a 28 nm process.
Memory
The R5 M230 has 4 GB of DDR3 memory, with a 1,000 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 16 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 R5 M230 includes 320 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 780 MHz and can dynamically boost its clock speed up to 855 MHz. Complementing the processing units are 20 texture mapping units (TMUs) for efficient texture filtering and 8 render output units (ROPs) for pixel processing.
Benchmark Performance
The R5 M230 has the 436th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 1.12% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
