Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce GTX 970
IntroThe GeForce 8600 GT 1GB DDR2 has a core clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce GTX 970, which has a clock frequency of 1050 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is comprised of 1664 SPUs, 104 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 will be 1650% faster than the GeForce 8600 GT 1GB DDR2 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 970 should be much (more or less 1164%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe GeForce GTX 970 is quite a bit (more or less 1456%) faster with regards to FSAA than the GeForce 8600 GT 1GB DDR2, and also will be able to handle 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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
