Compare any two graphics cards:
GeForce GT 1030 vs Radeon HD 3870 X2 1GB
IntroThe GeForce GT 1030 features a core clock frequency of 1265 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 64-bit memory bus, and makes use of a 16 nm design. It features 384 SPUs, 32 Texture Address Units, and 16 ROPs.Compare that to the Radeon HD 3870 X2 1GB, which comes with GPU core speed of 825 MHz, and 1024 MB of GDDR4 memory set to run at 1126 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3870 X2 1GB should in theory be quite a bit superior to the GeForce GT 1030 in general. (explain)
Texel RateThe GeForce GT 1030 will be a lot (more or less 53%) better at texture filtering than the Radeon HD 3870 X2 1GB. (explain)
Pixel RateThe Radeon HD 3870 X2 1GB should be quite a bit (about 30%) faster with regards to AA than the GeForce GT 1030, and will be able to handle higher 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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
