Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 870M
IntroThe GeForce GTX 260 Core 216 features clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 216 SPUs as well as 72 TAUs and 28 ROPs.Compare all that to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific model. It features 1344 SPUs along with 112 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 260 Core 216 should perform a small bit faster than the GeForce GTX 870M in general. (explain)
Texel RateThe GeForce GTX 870M will be a lot (approximately 154%) better at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe GeForce GTX 870M will be quite a bit (more or less 40%) more effective at AA than the GeForce GTX 260 Core 216, and also will be capable of handling higher resolutions without losing too much performance. (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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that are processed in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
