GeForce GT 440 1.5GB vs Radeon HD 6670 (OEM)
Intro
The GeForce GT 440 1.5GB has a core clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 ROPs.Compare all of that to the Radeon HD 6670 (OEM), which uses a 40 nm design. ATi has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular model. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
