Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 970
IntroThe GeForce 9800 GX2 has a core clock speed of 600 MHz and a GDDR3 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and uses a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare that to the GeForce GTX 970, which has a clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1664 SPUs, 104 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 970 should theoretically be much superior to the GeForce 9800 GX2 overall. (explain)
Texel RateThe GeForce GTX 970 will be a lot (approximately 42%) faster with regards to texture filtering than the GeForce 9800 GX2. (explain)
Pixel RateThe GeForce GTX 970 should be much (about 250%) better at AA than the GeForce 9800 GX2, and will be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant 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.
