Radeon HD 4730 vs Radeon HD 6570 (OEM) 2GB
Intro
The Radeon HD 4730 features a clock speed of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 6570 (OEM) 2GB, which uses a 40 nm design. ATi has clocked the core frequency at 650 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular model. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high 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 amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card 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 number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
