Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 3690/3830
IntroThe GeForce GT 240 GDDR5 1GB has clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 ROPs.Compare all of that to the Radeon HD 3690/3830, which has core clock speeds of 668 MHz on the GPU, and 828 MHz on the 256 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 240 GDDR5 1GB will be 105% quicker than the Radeon HD 3690/3830 overall, because of its higher data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be a lot (about 65%) more effective at AF than the Radeon HD 3690/3830. (explain)
Pixel RateThe Radeon HD 3690/3830 is quite a bit (more or less 143%) better at FSAA than the GeForce GT 240 GDDR5 1GB, and also should be able to handle higher resolutions more effectively. (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 (counted in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
