Radeon HD 5670 vs Radeon HD 5750 512MB

Intro

The Radeon HD 5670 has a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon HD 5750 512MB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 memory is set to run at a speed of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one 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 clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
