Compare any two graphics cards:
GeForce GTX 1070 Ti vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX 1070 Ti features a GPU core speed of 1607 MHz, and the 8192 MB of GDDR5 RAM runs at 2000 MHz through a 256-bit bus. It also features 2432 Stream Processors, 152 Texture Address Units, and 64 Raster Operation Units.Compare all of that to the Radeon HD 3870 X2 512MB, which has GPU core speed of 825 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 1070 Ti will be 128% faster than the Radeon HD 3870 X2 512MB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 1070 Ti will be a lot (more or less 825%) more effective at anisotropic filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateThe GeForce GTX 1070 Ti should be a lot (approximately 290%) more effective at full screen anti-aliasing than the Radeon HD 3870 X2 512MB, and will be capable of handling higher screen resolutions without losing too much performance. (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 information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 fill 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 ability to reach the maximum fill rate.
