GeForce GTX 560 vs Radeon RX 580

Intro

The GeForce GTX 560 uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 memory works at a frequency of 1001 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.

Compare those specs to the Radeon RX 580, which uses a 14 nm design. AMD has clocked the core frequency at 1257 MHz. The GDDR5 RAM is set to run at a frequency of 2000 MHz on this specific model. It features 2304 SPUs along with 144 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
