GeForce GT 450 (OEM) vs GeForce GTX 460 SE
Intro
The GeForce GT 450 (OEM) comes with a GPU core clock speed of 790 MHz, and the 1536 MB of GDDR5 memory runs at 1000 MHz through a 192-bit bus. It also features 144 SPUs, 24 TAUs, and 24 ROPs.Compare those specs to the GeForce GTX 460 SE, which uses a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this particular model. It features 288 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied 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 this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
