Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 4730
IntroThe GeForce GT 430 1GB uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.Compare all of that to the Radeon HD 4730, which makes use of a 55 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 memory runs at a frequency of 900 MHz on this particular model. It features 640(128x5) SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4730 should theoretically be much better than the GeForce GT 430 1GB overall. (explain)
Texel RateThe Radeon HD 4730 is quite a bit (more or less 100%) better at anisotropic filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 4730 is the winner, and very much so. (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 max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
