Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs Radeon HD 3690/3830
IntroThe GeForce 8600 GT 1GB GDDR3 has clock speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 memory. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon HD 3690/3830, which comes with a 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 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 3690/3830 should be just a bit faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe Radeon HD 3690/3830 is a lot (about 24%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 3690/3830 is a better choice, 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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
