GeForce GT 440 1.5GB vs Radeon HD 4670 1GB
Intro
The GeForce GT 440 1.5GB comes with a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 memory is set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 ROPs.Compare all of that to the Radeon HD 4670 1GB, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM set to run at 1100 MHz through a 128-bit bus. It also is made up of 320(64x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total 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 processed in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 potential to get to the max fill rate.
