GeForce GT 440 1.5GB vs Radeon HD 3470 512MB
Intro
The GeForce GT 440 1.5GB makes use of a 40 nm design. nVidia has set the core frequency at 594 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.Compare that to the Radeon HD 3470 512MB, which comes with a core clock frequency of 800 MHz and a GDDR3 memory frequency of 950 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It is made up of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
