Radeon RX 5700 XT vs Radeon RX 580

Intro

The Radeon RX 5700 XT features core speeds of 1605 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all that to the Radeon RX 580, which has a clock speed of 1257 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
