GeForce GTX 560 Ti vs Radeon HD 6970

Intro

The GeForce GTX 560 Ti features a core clock speed of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon HD 6970, which comes with a GPU core clock speed of 880 MHz, and 2048 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also features 1536 SPUs, 96 TAUs, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
