Radeon HD 5750 1GB vs Radeon HD 5830

Intro

The Radeon HD 5750 1GB features a GPU core speed of 700 MHz, and the 1024 MB of GDDR5 RAM runs at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 5830, which makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
