GeForce GTX 260 Core 216 vs GeForce GTX 275

Intro

The GeForce GTX 260 Core 216 comes with a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit memory bus, and makes use of a 65 nm design. It features 216 SPUs, 72 TAUs, and 28 Raster Operation Units.

Compare those specifications to the GeForce GTX 275, which comes with core clock speeds of 633 MHz on the GPU, and 1134 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
