GeForce GT 240 GDDR5 vs GeForce GT 430 1GB
Intro
The GeForce GT 240 GDDR5 has a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.Compare those specs to the GeForce GT 430 1GB, which has clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
