Radeon HD 5750 1GB vs Radeon HD 6850
Intro
The Radeon HD 5750 1GB has a GPU core clock speed of 700 MHz, and the 1024 MB of GDDR5 memory runs at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon HD 6850, which has GPU clock speed of 775 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 256-bit bus. It also is made up of 960 SPUs, 48 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.

Comments
One Response to “Radeon HD 5750 1GB vs Radeon HD 6850”Thanks for this. Very helpful. I have just upgraded from a faulty hd 5750 to a hd 6850. This article helped me get a sense of what kind of performance enhancement I should expect to find. The results were a little better than a I thought they would be, as everything seem to run a little better on the hd 6850, even at higher resolution and graphics quality settings. I would really recommend this card. It handles BF3 beautifully (at 1600 x 900, everthing on High quality, at a solid framerate, around 50 or so, whereas the hd 5750 could handle only med-lowish quality, at the same resolution and at about the same framerate). I bought the hd 5750 for $150 2 years ago, and bought the 6850 for the same price recently, with some solid gains in performance.
