Radeon HD 6670 (OEM) vs Radeon RX 560

Intro

The Radeon HD 6670 (OEM) comes with clock speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Compare that to the Radeon RX 560, which has a clock frequency of 1175 MHz and a GDDR5 memory speed of 7000 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
