GeForce GT 240 GDDR5 vs GeForce GT 430 1GB
Intro
The GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare all that to the GeForce GT 430 1GB, which comes with GPU core speed of 700 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 Texture Address Units, and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses 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, HDR and higher screen 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 number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
