Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX Titan
IntroThe GeForce 9800 GX2 has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare all that to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has set the core speed at 837 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this specific model. It features 2688 SPUs as well as 224 TAUs and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX Titan should be quite a bit faster than the GeForce 9800 GX2 overall. (explain)
Texel RateThe GeForce GTX Titan should be quite a bit (more or less 144%) more effective at texture filtering than the GeForce 9800 GX2. (explain)
Pixel RateThe GeForce GTX Titan should be quite a bit (more or less 109%) faster with regards to anti-aliasing than the GeForce 9800 GX2, and also capable of handling higher screen resolutions better. (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 maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
