Radeon RX 570 vs Radeon RX 590

Intro

The Radeon RX 570 uses a 14 nm design. AMD has clocked the core speed at 1168 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon RX 590, which comes with GPU core speed of 1469 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
