Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GTX 970M
IntroThe GeForce 8600 GT 256MB DDR2 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory works at a speed of 400 MHz on this model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specifications to the GeForce GTX 970M, which comes with 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 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 970M should theoretically be quite a bit faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 970M is much (more or less 756%) faster with regards to AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateThe GeForce GTX 970M should be much (about 927%) more effective at anti-aliasing than the GeForce 8600 GT 256MB DDR2, and should be able to handle higher screen resolutions while still performing well. (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 max amount of data (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card 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 applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
