Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 4830 1GB
IntroThe GeForce GT 340 1GB has a GPU core speed of 550 MHz, and the 1024 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare that to the Radeon HD 4830 1GB, which has GPU core speed of 575 MHz, and 1024 MB of GDDR4 memory running at 900 MHz through a 256-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4830 1GB will be 6% faster than the GeForce GT 340 1GB in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 4830 1GB will be just a bit (approximately 5%) better at anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 4830 1GB is superior to the GeForce GT 340 1GB, 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 max amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
