Radeon HD 6670 (OEM) vs Radeon HD 7970

Intro

The Radeon HD 6670 (OEM) features a GPU clock speed of 800 MHz, and the 512 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 Stream Processors, 24 TAUs, and 8 ROPs.

Compare that to the Radeon HD 7970, which uses a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 memory runs at a speed of 1375 MHz on this card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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.
