Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 3690/3830
IntroThe GeForce GT 430 has a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.Compare all of that to the Radeon HD 3690/3830, which makes use of a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 RAM is set to run at a frequency of 828 MHz on this card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 430 should theoretically be a bit superior to the Radeon HD 3690/3830 in general. (explain)
Texel RateThe GeForce GT 430 is a bit (more or less 5%) more effective at anisotropic filtering than the Radeon HD 3690/3830. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3690/3830 is the winner, 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 data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If 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, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
