GeForce GTX 560 Ti 448 vs Radeon HD 6950 2GB

Intro

The GeForce GTX 560 Ti 448 has clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 RAM. It features 448 SPUs as well as 56 TAUs and 40 ROPs.

Compare those specs to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this particular card. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
