Radeon RX 570 vs Radeon RX 590

Intro

The Radeon RX 570 makes use of a 14 nm design. AMD has clocked the core speed at 1168 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Compare those specs to the Radeon RX 590, which features GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
