GeForce GT 440 3GB vs Radeon HD 3470 256MB
Intro
The GeForce GT 440 3GB has a core clock speed of 594 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It features 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare those specifications to the Radeon HD 3470 256MB, which features core speeds of 800 MHz on the GPU, and 950 MHz on the 256 MB of DDR2 memory. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
