Compare any two graphics cards:
Radeon HD 5870 vs Radeon HD 6950 2GB
IntroThe Radeon HD 5870 has a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is made up of 1600(320x5) SPUs, 80 TAUs, and 32 ROPs.Compare all of that to the Radeon HD 6950 2GB, which has GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory running at 1250 MHz through a 256-bit bus. It also is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6950 2GB should perform a small bit faster than the Radeon HD 5870 overall. (explain)
Texel RateThe Radeon HD 6950 2GB should be just a bit (about 4%) more effective at texture filtering than the Radeon HD 5870. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 5870 is the winner, not by a very large margin though. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

One Response to “Radeon HD 5870 vs Radeon HD 6950 2GB”Warning!
ALL of HD5xxx series support OpenGL4.1
Please update the information.
You can see for reference wikipedia "comparison of amd units" page.
Thanks
