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 set the core frequency at 675 MHz. The GDDR3 memory is set to run at a speed of 1000 MHz on this card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare that to the Radeon HD 3690/3830, which has clock speeds of 668 MHz on the GPU, and 828 MHz on the 256 MB of GDDR3 memory. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce 8600 GTS, in theory, should be a lot faster than the Radeon HD 3690/3830 overall. (explain)
Texel RateThe GeForce 8600 GTS will be just a bit (more or less 1%) more effective at texture filtering than the Radeon HD 3690/3830. (explain)
Pixel RateThe Radeon HD 3690/3830 is a lot (approximately 98%) better at full screen anti-aliasing than the GeForce 8600 GTS, and also will be capable of handling 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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 the local memory per second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
