Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 780 Ti
IntroThe GeForce 8600 GT 512MB DDR2 has a GPU clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare those specs to the GeForce GTX 780 Ti, which features core clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 2880 SPUs along with 240 Texture Address Units and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 780 Ti should theoretically be quite a bit better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (approximately 2331%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 780 Ti is the winner, by far. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate also depends 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 reach the maximum fill rate.
