Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 870M
IntroThe GeForce 9500 GT DDR2 uses a 65 nm design. nVidia has set the core speed at 550 MHz. The DDR2 RAM runs at a speed of 500 MHz on this specific model. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the GeForce GTX 870M, which features GPU clock speed of 941 MHz, and 3072 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 870M should theoretically be quite a bit better than the GeForce 9500 GT DDR2 in general. (explain)
Texel RateThe GeForce GTX 870M will be quite a bit (approximately 1098%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce GTX 870M should be much (approximately 413%) better at AA than the GeForce 9500 GT DDR2, and should be capable of handling higher screen resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
