GeForce 9800 GTX vs GeForce GTX 460

Intro

The GeForce 9800 GTX comes with a clock frequency of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specs to the GeForce GTX 460, which features a core clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 24 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
