Compare any two graphics cards:
Radeon HD 5830 vs Radeon HD 6950 2GB
IntroThe Radeon HD 5830 comes with a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 TAUs, and 16 ROPs.Compare those specifications to the Radeon HD 6950 2GB, which has a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is made up of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6950 2GB should theoretically be quite a bit better than the Radeon HD 5830 in general. (explain)
Texel RateThe Radeon HD 6950 2GB should be much (more or less 57%) more effective at anisotropic filtering than the Radeon HD 5830. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6950 2GB is a better choice, and very much so. (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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount 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 clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
