Radeon HD 6670 (OEM) vs Radeon RX 560

Intro

The Radeon HD 6670 (OEM) features a GPU core speed of 800 MHz, and the 512 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon RX 560, which comes with core clock speeds of 1175 MHz on the GPU, and 7000 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
