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

Intro

The Radeon HD 5750 1GB features a GPU clock speed of 700 MHz, and the 1024 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon HD 6670 (OEM), which uses a 40 nm design. ATi has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
