Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs GeForce GTX 870M
IntroThe GeForce GTX 650 Ti 2GB comes with a core clock speed of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specs to the GeForce GTX 870M, which uses a 28 nm design. nVidia has set the core speed at 941 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 1344 SPUs as well as 112 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthIn theory, the GeForce GTX 870M should be a little bit faster than the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 870M is quite a bit (about 77%) better at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 870M is a better choice, and very much so. (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 worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
