GeForce GTX 460 (OEM) vs GeForce GTX 465
Intro
The GeForce GTX 460 (OEM) features a GPU core clock speed of 650 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 TAUs, and 32 ROPs.Compare those specs to the GeForce GTX 465, which uses a 40 nm design. nVidia has clocked the core frequency at 607 MHz. The GDDR5 RAM is set to run at a frequency of 802 MHz on this particular model. It features 352 SPUs along with 44 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total 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 in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
