GeForce GT 440 3GB vs Radeon HD 3470 512MB
Intro
The GeForce GT 440 3GB has a clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare that to the Radeon HD 3470 512MB, which comes with clock 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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
