Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5770
IntroThe GeForce 9800 GTX comes with a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon HD 5770, which comes with GPU core speed of 850 MHz, and 1024 MB of GDDR5 RAM running at 1200 MHz through a 128-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5770 should theoretically be just a bit faster than the GeForce 9800 GTX overall. (explain)
Texel RateThe GeForce 9800 GTX is a lot (more or less 27%) more effective at texture filtering than the Radeon HD 5770. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5770 is a better choice, 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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This is calculated 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 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 most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
