Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 3470 512MB
IntroThe GeForce GT 240 GDDR5 1GB features core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 3470 512MB, which uses a 55 nm design. AMD has set the core frequency at 800 MHz. The GDDR3 RAM runs at a speed of 950 MHz on this model. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GT 240 GDDR5 1GB should be 79% faster than the Radeon HD 3470 512MB in general, because of its higher data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be quite a bit (more or less 450%) more effective at anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 240 GDDR5 1GB is superior to the Radeon HD 3470 512MB, and very much so. (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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR 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 anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
