Radeon HD 5830 vs Radeon HD 5850
Intro
The Radeon HD 5830 comes with a clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 256-bit bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.Compare all that to the Radeon HD 5850, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

Memory Bandwidth
Both cards have exactly the same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel Rate
The Radeon HD 5850 should be a bit (more or less 17%) better at anisotropic filtering than the Radeon HD 5830. (explain)| Radeon HD 5850 |

52200 Mtexels/sec |
| Radeon HD 5830 |
|
44800 Mtexels/sec |

Pixel Rate
The Radeon HD 5850 should be much (about 81%) faster with regards to AA than the Radeon HD 5830, and capable of handling higher screen resolutions more effectively. (explain)| Radeon HD 5850 |
|
23200 Mpixels/sec |
| Radeon HD 5830 |

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it 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 AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
