Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs GeForce GTX 870M
IntroThe GeForce 9500 GT 1GB GDDR3 has a core clock speed of 550 MHz and a GDDR3 memory speed of 800 MHz. It also features a 128-bit memory bus, and uses a 55 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce GTX 870M, which comes with a clock frequency of 941 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 870M should in theory be much superior to the GeForce 9500 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GTX 870M is quite a bit (more or less 1098%) faster with regards to AF than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 870M is a better choice, 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
