GeForce GT 240 GDDR5 1GB vs Radeon HD 3470 512MB
Intro
The GeForce GT 240 GDDR5 1GB comes with a core clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 32 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 3470 512MB, which features core speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 RAM. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
