Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs GeForce 940M
IntroThe GeForce 8800 GTS (G80) 320MB has a clock frequency of 513 MHz and a GDDR3 memory speed of 792 MHz. It also uses a 320-bit bus, and uses a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specs to the GeForce 940M, which uses a 28 nm design. nVidia has set the core speed at 1072 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce 8800 GTS (G80) 320MB should perform quite a bit faster than the GeForce 940M overall. (explain)
Texel RateThe GeForce 940M is a small bit (more or less 4%) more effective at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 320MB will be a bit (approximately 20%) more effective at FSAA than the GeForce 940M, and also will be capable of handling higher screen 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 largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
