GeForce GTX 560 vs Radeon RX 580

Intro

The GeForce GTX 560 comes with a core clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 580, which makes use of a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 memory is set to run at a frequency of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
