Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce 940M
IntroThe GeForce 8600 GT 512MB DDR2 has clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare all that to the GeForce 940M, which has core clock speeds of 1072 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 940M, in theory, should perform a lot faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce 940M is quite a bit (more or less 198%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce 940M will be a lot (about 99%) more effective at AA than the GeForce 8600 GT 512MB DDR2, and should be capable of handling higher resolutions while still performing well. (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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
