GeForce GTX 560 Ti 448 vs Radeon HD 6970

Intro

The GeForce GTX 560 Ti 448 has a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM is set to run at 900 MHz through a 320-bit bus. It also features 448 Stream Processors, 56 TAUs, and 40 ROPs.

Compare all of that to the Radeon HD 6970, which comes with a clock frequency of 880 MHz and a GDDR5 memory frequency of 1375 MHz. It also features a 256-bit bus, and uses a 40 nm design. It features 1536 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
