Compare any two graphics cards:
GeForce GT 420 vs Radeon HD 3650 256MB
IntroThe GeForce GT 420 has a GPU core clock speed of 700 MHz, and the 2048 MB of GDDR3 memory runs at 900 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 8 TAUs, and 4 Raster Operation Units.Compare all of that to the Radeon HD 3650 256MB, which features core clock speeds of 725 MHz on the GPU, and 800 MHz on the 256 MB of DDR2 RAM. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 420 should be a small bit faster than the Radeon HD 3650 256MB in general. (explain)
Texel RateThe Radeon HD 3650 256MB is a little bit (about 4%) faster with regards to AF than the GeForce GT 420. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 3650 256MB is the winner, though only just barely. (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 (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
