Radeon RX 560 vs Radeon RX 590

Intro

The Radeon RX 560 comes with core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare all that to the Radeon RX 590, which features a core clock speed of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
