Radeon HD 5750 1GB vs Radeon HD 6670 (OEM)

Intro

The Radeon HD 5750 1GB uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory runs at a speed of 1150 MHz on this specific model. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 6670 (OEM), which comes with GPU clock speed of 800 MHz, and 512 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
