GeForce GTX 560 Ti vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory is set to run at a speed of 1002 MHz on this specific model. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 560 Ti 448, which comes with a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 900 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 TAUs, and 40 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card 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 processed per 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. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
