Radeon HD 5750 1GB vs Radeon HD 6750

Intro

The Radeon HD 5750 1GB features a core clock frequency of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Compare all of that to the Radeon HD 6750, which comes with GPU clock speed of 725 MHz, and 512 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 Texture Address Units, and 16 ROPs.

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

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

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