Compare any two graphics cards:
Nvidia Titan X vs Radeon R9 290
IntroThe Nvidia Titan X uses a 16 nm design. nVidia has set the core speed at 1417 MHz. The GDDR5X RAM is set to run at a speed of 1251 MHz on this specific card. It features 3584 SPUs as well as 224 Texture Address Units and 96 Rasterization Operator Units.
Compare all of that to the Radeon R9 290, which comes with GPU clock speed of 800 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 512-bit bus. It also features 2560 Stream Processors, 160 Texture Address Units, and 64 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Nvidia Titan X, in theory, should be much faster than the Radeon R9 290 overall. (explain)
Texel RateThe Nvidia Titan X will be a lot (more or less 148%) more effective at anisotropic filtering than the Radeon R9 290. (explain)
Pixel RateThe Nvidia Titan X is a lot (about 166%) faster with regards to anti-aliasing than the Radeon R9 290, and will be capable of handling higher resolutions more effectively. (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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one 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. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
