GeForce GTX 260 vs GeForce GTX 660

Intro

The GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM is set to run at a frequency of 999 MHz on this model. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.

Compare that to the GeForce GTX 660, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 192-bit bus. It also features 960 Stream Processors, 80 TAUs, and 24 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
