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 made up of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare all that to the Radeon HD 4830 1GB, which features core speeds of 575 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR4 RAM. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 4830 1GB should be a small bit faster than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon HD 4830 1GB will be a little bit (about 5%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 4830 1GB will be much (more or less 109%) more effective at anti-aliasing than the GeForce GT 340 1GB, and should be capable of handling higher screen resolutions without losing too much performance. (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 (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
