Summary
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.
About the AMD Radeon HD 7750 GPU
The AMD Radeon HD 7750 is an end-of-life desktop graphics card that released in Q1 2012 with a MSRP of $109. It is built on the GCN 1.0 GPU microarchitecture (codename Cape Verde) and is manufactured on a 28 nm process.
Memory
The HD 7750 has 1,024 MB of GDDR5 memory, with a 1,125 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 72 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 HD 7750 includes 512 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 800 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 HD 7750 is a compact, low-profile graphics card that fits into 1 PCIe expansion slot. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 55 W.
