Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 4830 512MB
IntroThe GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 RAM works at a frequency of 970 MHz on this card. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4830 512MB, which comes with a clock frequency of 575 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GTS (G92) should in theory be a small bit superior to the Radeon HD 4830 512MB overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) should be a lot (more or less 126%) better at anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateThe GeForce 8800 GTS (G92) is a small bit (more or less 13%) more effective at AA than the Radeon HD 4830 512MB, and will be able to handle higher screen resolutions more effectively. (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 data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
