GeForce GTX 560 Ti vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 560 Ti comes with a GPU clock speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the GeForce GTX 560 Ti 448, which has clock speeds of 732 MHz on the GPU, and 900 MHz on the 1280 MB of GDDR5 memory. It features 448 SPUs as well as 56 Texture Address Units and 40 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
