Compare any two graphics cards:
Radeon HD 5850 vs Radeon HD 6870
IntroThe Radeon HD 5850 uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 6870, which has a clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It is made up of 1120 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthPerformance-wise, the Radeon HD 6870 should theoretically be just a bit superior to the Radeon HD 5850 overall. (explain)
Texel RateThe Radeon HD 5850 is a small bit (approximately 4%) better at anisotropic filtering than the Radeon HD 6870. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6870 is the winner, by far. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
