GeForce GTX 275 vs GeForce GTX 560 Ti 448

Intro

The GeForce GTX 275 comes with a clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

Compare those specifications to the GeForce GTX 560 Ti 448, which has GPU 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 comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
