Summary
About the NVIDIA Quadro P400 GPU
The NVIDIA Quadro P400 is an end-of-life workstation graphics card that released in Q1 2017. It is built on the Pascal GPU microarchitecture (codename GP107) and is manufactured on a 14 nm process.
Memory
The P400 has 2 GB of GDDR5 memory, with a 1,002 MHz memory clock and a 64 bit interface. This gives it a memory bandwidth of 32.06 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 P400 includes 256 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,228 MHz and can dynamically boost its clock speed up to 1,252 MHz. Complementing the processing units are 16 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The P400 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports mini-DisplayPort 1.4a display connections. NVIDIA recommends a power supply of at least 200 W to handle the GPU's thermal design power (TDP) of 30 W.
About the NVIDIA Quadro K620 GPU
The NVIDIA Quadro K620 is an end-of-life workstation graphics card that released in Q3 2014. It is built on the Maxwell GPU microarchitecture (codename GM107) and is manufactured on a 28 nm process.
Memory
The K620 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 K620 includes 384 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,058 MHz and can dynamically boost its clock speed up to 1,124 MHz. Complementing the processing units are 24 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The K620 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 200 W to handle the GPU's thermal design power (TDP) of 45 W.
