Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 970M
IntroThe GeForce GTX 260 216SP 55 nm features a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 Texture Address Units, and 28 ROPs.Compare all of that to the GeForce GTX 970M, which features GPU core speed of 924 MHz, and 3072 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is made up of 1280 SPUs, 80 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 260 216SP 55 nm should theoretically be a little bit better than the GeForce GTX 970M overall. (explain)
Texel RateThe GeForce GTX 970M will be much (more or less 78%) more effective at AF than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateThe GeForce GTX 970M should be much (approximately 175%) faster with regards to FSAA than the GeForce GTX 260 216SP 55 nm, and should be capable of handling higher resolutions more effectively. (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 information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 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 anti-aliasing, 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 figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
