Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 3690/3830
IntroThe GeForce 8600 GT 256MB GDDR3 features a clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specifications to the Radeon HD 3690/3830, which has a core clock frequency of 668 MHz and a GDDR3 memory speed of 828 MHz. It also features a 128-bit memory bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 3690/3830 should theoretically be just a bit superior to the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon HD 3690/3830 is much (more or less 24%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 3690/3830 is superior to the GeForce 8600 GT 256MB GDDR3, and very much so. (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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
