GeForce GT 430 1GB vs GeForce GT 450 (OEM)
Intro
The GeForce GT 430 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular card. It features 96 SPUs as well as 16 TAUs and 4 Rasterization Operator Units.Compare all of that to the GeForce GT 450 (OEM), which has GPU clock speed of 790 MHz, and 1536 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
