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

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
