Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Geforce GTX 780
IntroThe GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare all that to the Geforce GTX 780, which comes with a clock speed of 863 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2304 SPUs, 192 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Geforce GTX 780 should theoretically be quite a bit superior to the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Geforce GTX 780 should be quite a bit (more or less 1818%) more effective at texture 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 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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
