About the NVIDIA GeForce GTX 660 GPU
The NVIDIA GeForce GTX 660 is an end-of-life desktop graphics card that released in Q3 2012 with a MSRP of $229. It is built on the Kepler GPU microarchitecture (codename GK106) and is manufactured on a 28 nm process.
Memory
The GTX 660 has 2 GB of GDDR5 memory, with a 1,502 MHz memory clock and a 192 bit interface. This gives it a memory bandwidth of 144.2 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 GTX 660 includes 960 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 980 MHz and can dynamically boost its clock speed up to 1,032 MHz. Complementing the processing units are 80 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The GTX 660 occupies 2 PCIe expansion slots. It supports DVI, HDMI 1.4a, DisplayPort 1.2 display connections. NVIDIA recommends a power supply of at least 300 W to handle the GPU's thermal design power (TDP) of 140 W.
About the AMD Radeon RX 560 GPU
The AMD Radeon RX 560 is a desktop graphics card that launched in Q2 2017 with a MSRP of $99. It is built on the GCN 4.0 GPU microarchitecture (codename Polaris 21) and is manufactured on a 14 nm process.
Memory
The RX 560 has 4 GB of GDDR5 memory, with a 1,750 MHz memory clock and a 128 bit interface. This gives it a memory bandwidth of 112 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 RX 560 includes 1,024 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,175 MHz and can dynamically boost its clock speed up to 1,275 MHz. Complementing the processing units are 64 texture mapping units (TMUs) for efficient texture filtering and 16 render output units (ROPs) for pixel processing.
Compatibility & Power Consumption
The RX 560 occupies 2 PCIe expansion slots. It supports DVI, HDMI 2.0b, DisplayPort 1.4a display connections. AMD recommends a power supply of at least 250 W to handle the GPU's thermal design power (TDP) of 75 W.
