GeForce GT 450 (OEM) vs GeForce GTX 460 (OEM)
Intro
The GeForce GT 450 (OEM) has a clock frequency of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is comprised of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.Compare all of that to the GeForce GTX 460 (OEM), which features a clock frequency of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
