Compare any two graphics cards:
GeForce 920M vs GeForce GT 240 GDDR5
IntroThe GeForce 920M features a core clock frequency of 954 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It features 384 SPUs, 32 Texture Address Units, and 8 ROPs.Compare those specs to the GeForce GT 240 GDDR5, which features GPU clock speed of 550 MHz, and 512 MB of GDDR5 memory set to run at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GT 240 GDDR5 should be quite a bit faster than the GeForce 920M overall. (explain)
Texel RateThe GeForce 920M will be a lot (more or less 73%) more effective at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 920M is the winner, 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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
