Compare any two graphics cards:
GeForce GTX 1070 Ti vs Radeon HD 4870 X2
IntroThe GeForce GTX 1070 Ti features a GPU core clock speed of 1607 MHz, and the 8192 MB of GDDR5 memory runs at 2000 MHz through a 256-bit bus. It also is made up of 2432 Stream Processors, 152 Texture Address Units, and 64 Raster Operation Units.Compare those specs to the Radeon HD 4870 X2, which features a clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 55 nm design. It features 800(160x5) SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 1070 Ti should be a bit faster than the Radeon HD 4870 X2 in general. (explain)
Texel RateThe GeForce GTX 1070 Ti will be much (more or less 307%) more effective at anisotropic filtering than the Radeon HD 4870 X2. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 1070 Ti is superior to the Radeon HD 4870 X2, by far. (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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
