Radeon HD 6670 (OEM) 1GB vs Radeon RX 560

Intro

The Radeon HD 6670 (OEM) 1GB comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the Radeon RX 560, which has clock speeds of 1175 MHz on the GPU, and 7000 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
