Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 4830 512MB
IntroThe GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory runs at a frequency of 970 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.Compare that to the Radeon HD 4830 512MB, which comes with clock speeds of 575 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTS (G92) should theoretically be a little bit better than the Radeon HD 4830 512MB overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) is a lot (approximately 126%) faster with regards to anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GTS (G92) is the winner, but it probably won't make a huge difference. (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 max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
