Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon HD 3690/3830
IntroThe GeForce 8600 GT 512MB GDDR3 features a GPU clock speed of 540 MHz, and the 512 MB of GDDR3 RAM runs at 700 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 3690/3830, which has core clock speeds of 668 MHz on the GPU, and 828 MHz on the 256 MB of GDDR3 RAM. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3690/3830 should theoretically perform a small bit faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe Radeon HD 3690/3830 should be quite a bit (about 24%) faster with regards to AF than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateThe Radeon HD 3690/3830 will be much (more or less 147%) faster with regards to FSAA than the GeForce 8600 GT 512MB GDDR3, and will be capable of handling higher resolutions better. (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 data (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
