About the AMD Radeon Pro Vega 20 GPU

The AMD Radeon Pro Vega 20 is a mobile graphics card that launched in Q4 2018. It is built on the GCN 5.0 GPU microarchitecture (codename Vega 12) and is manufactured on a 14 nm process.

Memory

The Pro Vega 20 has 4 GB of HBM2 memory, with a 740 MHz memory clock and a 1,024 bit interface. This gives it a memory bandwidth of 189.4 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 Pro Vega 20 includes 1,280 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 815 MHz and can dynamically boost its clock speed up to 1,283 MHz. Complementing the processing units are 80 texture mapping units (TMUs) for efficient texture filtering and 32 render output units (ROPs) for pixel processing.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 100 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The Pro Vega 20 has the 159th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 11.75% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.

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.
