GeForce GTX 460 2GB vs GeForce GTX 470

Intro

The GeForce GTX 460 2GB features a GPU clock speed of 675 MHz, and the 2048 MB of GDDR5 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare those specifications to the GeForce GTX 470, which has GPU core speed of 607 MHz, and 1280 MB of GDDR5 memory set to run at 837 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
