Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 750
IntroThe GeForce 8600 GT 512MB DDR2 features a core clock speed of 540 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit memory bus, and uses a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare all that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 750 will be 525% faster than the GeForce 8600 GT 512MB DDR2 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 750 should be a lot (more or less 278%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 750 is the winner, by a large margin. (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 (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
