Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 3690/3830
IntroThe GeForce GT 430 features clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 96 SPUs as well as 16 TAUs and 4 ROPs.Compare all of that to the Radeon HD 3690/3830, which features GPU clock speed of 668 MHz, and 256 MB of GDDR3 memory running at 828 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 430 will be 9% faster than the Radeon HD 3690/3830 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GT 430 will be a little bit (more or less 5%) more effective at AF than the Radeon HD 3690/3830. (explain)
Pixel RateThe Radeon HD 3690/3830 will be much (approximately 282%) better at AA than the GeForce GT 430, and should be able to handle higher screen 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
