Radeon HD 4730 vs Radeon HD 5670
Intro
The Radeon HD 4730 has a clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 5670, which uses a 40 nm design. AMD has clocked the core speed at 775 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular model. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core 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 most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
