Compare any two graphics cards:
GeForce GTX 580 3GB vs GeForce GTX 950M
IntroThe GeForce GTX 580 3GB uses a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this model. It features 512 SPUs along with 64 TAUs and 48 ROPs.Compare that to the GeForce GTX 950M, which has clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB, in theory, should perform much faster than the GeForce GTX 950M overall. (explain)
Texel RateThe GeForce GTX 580 3GB is much (about 35%) faster with regards to AF than the GeForce GTX 950M. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 3GB is superior to the GeForce GTX 950M, by a large margin. (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 data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at 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 the graphics card 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 Render Output Units 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
