Compare any two graphics cards:
GeForce 9600 GSO 768MB vs Radeon R9 390 8G
IntroThe GeForce 9600 GSO 768MB comes with a core clock speed of 550 MHz and a GDDR3 memory speed of 800 MHz. It also features a 192-bit memory bus, and uses a 65 nm design. It is made up of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.Compare that to the Radeon R9 390 8G, which features a clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 512-bit memory bus, and makes use of a 28 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390 8G will be 900% quicker than the GeForce 9600 GSO 768MB overall, because of its greater data rate. (explain)
Texel RateThe Radeon R9 390 8G will be much (about 506%) better at texture filtering than the GeForce 9600 GSO 768MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 390 8G is superior to the GeForce 9600 GSO 768MB, 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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
