Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 870M
IntroThe GeForce GTX 260 Core 216 makes use of a 65 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory is set to run at a frequency of 999 MHz on this particular card. It features 216 SPUs as well as 72 TAUs and 28 ROPs.Compare those specs to the GeForce GTX 870M, which has GPU clock speed of 941 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 260 Core 216, in theory, should be a small bit faster than the GeForce GTX 870M in general. (explain)
Texel RateThe GeForce GTX 870M is quite a bit (approximately 154%) faster with regards to AF than the GeForce GTX 260 Core 216. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 870M is the winner, 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
