Radeon HD 5750 1GB vs Radeon HD 6850
Intro
The Radeon HD 5750 1GB has a GPU clock speed of 700 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.Compare that to the Radeon HD 6850, which features a core clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It features 960 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock 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 processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability 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.
