AMD Radeon R9 M395 (Mac Edition) vs NVIDIA Quadro M620

The NVIDIA Quadro M620 is an end-of-life mobile graphics card that released in Q1 2017. It is built on the Maxwell GPU microarchitecture (codename GM107) and is manufactured on a 28 nm process.

Memory

The M620 has 2 GB of GDDR5 memory, with a 1,253 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 80.19 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 M620 includes 512 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 756 MHz and can dynamically boost its clock speed up to 1,018 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 30 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The M620 has the 276th best 3DMark 11 Performance GPU score among the 543 benchmarked GPUs in our database. It achieves 3.63% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 4090.
