GeForce GTX 260 216SP 55 nm vs GeForce GTX 275
Intro
The GeForce GTX 260 216SP 55 nm has a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and uses a 55 nm design. It features 216 SPUs, 72 TAUs, and 28 ROPs.Compare those specifications to the GeForce GTX 275, which features clock speeds of 633 MHz on the GPU, and 1134 MHz on the 896 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
