Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 4650 512MB
IntroThe GeForce GT 430 1GB comes with a clock speed of 700 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.Compare that to the Radeon HD 4650 512MB, which uses a 55 nm design. AMD has set the core frequency at 600 MHz. The DDR2 memory works at a frequency of 500 MHz on this specific model. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 430 1GB should theoretically be quite a bit faster than the Radeon HD 4650 512MB overall. (explain)
Texel RateThe Radeon HD 4650 512MB is much (about 71%) better at anisotropic filtering than the GeForce GT 430 1GB. (explain)
Pixel RateThe Radeon HD 4650 512MB is quite a bit (about 71%) faster with regards to AA than the GeForce GT 430 1GB, and should be able to handle 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 largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 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 applied per second. This figure is calculated by multiplying the total texture units by the core 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
