Compare any two graphics cards:
GeForce 8800 Ultra vs Radeon HD 5830
IntroThe GeForce 8800 Ultra uses a 90 nm design. nVidia has clocked the core speed at 612 MHz. The GDDR3 RAM works at a frequency of 1080 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 24 ROPs.Compare those specs to the Radeon HD 5830, which features a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It features 1120(224x5) SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5830 will be 23% quicker than the GeForce 8800 Ultra in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 5830 will be just a bit (approximately 14%) faster with regards to anisotropic filtering than the GeForce 8800 Ultra. (explain)
Pixel RateThe GeForce 8800 Ultra is a small bit (approximately 15%) better at AA than the Radeon HD 5830, and will be capable of handling higher resolutions without losing too much performance. (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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
