Radeon HD 5750 512MB vs Radeon HD 6670 (OEM)

Intro

The Radeon HD 5750 512MB comes with core speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon HD 6670 (OEM), which features GPU core speed of 800 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 480 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
