Compare any two graphics cards:
Radeon HD 5770 vs Radeon HD 6950
IntroThe Radeon HD 5770 uses a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this particular card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6950, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1250 MHz on this particular card. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6950 is 108% faster than the Radeon HD 5770 in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon HD 6950 will be much (about 107%) better at texture filtering than the Radeon HD 5770. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6950 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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card 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 maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
