Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GTX 970
IntroThe GeForce 8600 GT 1GB GDDR3 features core clock speeds of 540 MHz on the GPU, and 700 MHz on the 1024 MB of GDDR3 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GTX 970, which comes with a core clock frequency of 1050 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It features 1664 SPUs, 104 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 970 should in theory be much better than the GeForce 8600 GT 1GB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 970 will be much (approximately 1164%) better at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 970 is the winner, and very much so. (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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
