Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce GTX 970
IntroThe GeForce 8600 GT 1GB DDR2 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM is set to run at a frequency of 400 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce GTX 970, which comes with a clock speed of 1050 MHz and a GDDR5 memory speed 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 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 970 should be 1650% quicker than the GeForce 8600 GT 1GB DDR2 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 970 is quite a bit (more or less 1164%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe GeForce GTX 970 is a lot (about 1456%) more effective at anti-aliasing than the GeForce 8600 GT 1GB DDR2, and capable of handling higher screen resolutions better. (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 (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number 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 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. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
