AMD Radeon PRO V620

The AMD Radeon PRO V620 is an end-of-life workstation graphics card that released in Q4 2021. It is built on the RDNA 2.0 GPU microarchitecture (codename Navi 21) and is manufactured on a 7 nm process.

Memory

The PRO V620 has 32 GB of GDDR6 memory, with a 2,000 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 512 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 V620 includes 4,608 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,825 MHz and can dynamically boost its clock speed up to 2,200 MHz. Complementing the processing units are 288 texture mapping units (TMUs) for efficient texture filtering and 128 render output units (ROPs) for pixel processing. Additionally, the GPU features 72 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The PRO V620 occupies 2 PCIe expansion slots. AMD recommends a power supply of at least 700 W to handle the GPU's thermal design power (TDP) of 300 W.
