Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon R9 390X 8G
IntroThe GeForce 9800 GX2 features a clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare all of that to the Radeon R9 390X 8G, which features core clock speeds of 1050 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 memory. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390X 8G should perform much faster than the GeForce 9800 GX2 in general. (explain)
Texel RateThe Radeon R9 390X 8G will be quite a bit (more or less 141%) more effective at anisotropic filtering than the GeForce 9800 GX2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 390X 8G 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
