GeForce 9800 GTX vs GeForce GTX 460
Intro
The GeForce 9800 GTX comes with a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the GeForce GTX 460, which comes with a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 TAUs, and 24 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
