GeForce GTX 260 216SP 55 nm vs GeForce GTX 465

Intro

The GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this card. It features 216 SPUs as well as 72 TAUs and 28 ROPs.

Compare those specifications to the GeForce GTX 465, which has a core clock frequency of 607 MHz and a GDDR5 memory speed of 802 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
