GeForce GTX 560 Ti 448 vs Radeon HD 6970

Intro

The GeForce GTX 560 Ti 448 makes use of a 40 nm design. nVidia has set the core speed at 732 MHz. The GDDR5 memory works at a frequency of 900 MHz on this particular model. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.

Compare all that to the Radeon HD 6970, which features core speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 96 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
