Compare any two graphics cards:
GeForce GT 430 vs Radeon HD 3690/3830
IntroThe GeForce GT 430 uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.Compare all of that to the Radeon HD 3690/3830, which comes with 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 GeForce GT 430, in theory, should perform just a bit faster than the Radeon HD 3690/3830 overall. (explain)
Texel RateThe GeForce GT 430 will be a small bit (about 5%) better at anisotropic filtering than the Radeon HD 3690/3830. (explain)
Pixel RateThe Radeon HD 3690/3830 will be a lot (approximately 282%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also 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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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.
