GeForce GTX 460 vs GeForce GTX 465
Intro
The GeForce GTX 460 has a GPU core speed of 675 MHz, and the 768 MB of GDDR5 memory is set to run at 900 MHz through a 192-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.Compare all of that to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 memory runs at a speed of 802 MHz on this model. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 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. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
