GeForce GTX 260 216SP 55 nm vs GeForce GTX 470

Intro

The GeForce GTX 260 216SP 55 nm comes with a 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 55 nm design. It is made up of 216 SPUs, 72 TAUs, and 28 Raster Operation Units.

Compare that to the GeForce GTX 470, which comes with GPU core speed of 607 MHz, and 1280 MB of GDDR5 memory running at 837 MHz through a 320-bit bus. It also features 448 Stream Processors, 56 TAUs, and 40 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
