Compare any two graphics cards:
GeForce 8600 GTS vs Radeon HD 3690/3830
IntroThe GeForce 8600 GTS makes use of a 80 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR3 memory is set to run at a speed of 1000 MHz on this specific model. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon HD 3690/3830, which makes use of a 55 nm design. AMD has clocked the core frequency at 668 MHz. The GDDR3 RAM works at a speed of 828 MHz on this specific model. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the GeForce 8600 GTS should perform quite a bit faster than the Radeon HD 3690/3830 overall. (explain)
Texel RateThe GeForce 8600 GTS will be a small bit (about 1%) better at texture filtering than the Radeon HD 3690/3830. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 3690/3830 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface 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 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock 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 processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
