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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 3690/3830 should be a small bit faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe Radeon HD 3690/3830 is quite a bit (approximately 24%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe Radeon HD 3690/3830 should be much (approximately 147%) faster with regards to anti-aliasing than the GeForce 8600 GT 256MB GDDR3, and should be capable of handling higher screen resolutions without slowing down too much. (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 information (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If 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 are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels 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 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
