Radeon HD 5830 vs Radeon HD 5850
Intro
The Radeon HD 5830 makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 5850, which uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular model. It features 1440(288x5) SPUs along with 72 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
