Radeon HD 7950 vs Radeon RX 590

Intro

The Radeon HD 7950 comes with a GPU clock speed of 800 MHz, and the 1536 MB of GDDR5 memory is set to run at 1250 MHz through a 384-bit bus. It also features 1792 Stream Processors, 112 Texture Address Units, and 32 ROPs.

Compare all of that to the Radeon RX 590, which features GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
