Radeon HD 4730 vs Radeon HD 6670 (OEM)
Intro
The Radeon HD 4730 makes use of a 55 nm design. ATi has set the core speed at 700 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this card. It features 640(128x5) SPUs along with 32 TAUs and 8 ROPs.Compare all of that to the Radeon HD 6670 (OEM), which makes use of a 40 nm design. ATi has clocked the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the ability to reach the max fill rate.
