Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 970M
IntroThe GeForce 8600 GT 1GB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM works at a frequency of 700 MHz on this particular model. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare those specifications to the GeForce GTX 970M, which uses a 28 nm design. nVidia has set the core speed at 924 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this card. It features 1280 SPUs along with 80 Texture Address Units and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 970M will be 329% quicker than the GeForce 8600 GT 1GB GDDR3 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 970M should be much (approximately 756%) faster with regards to AF than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce GTX 970M is a lot (more or less 927%) faster with regards to AA than the GeForce 8600 GT 1GB GDDR3, and 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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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 number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
