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 runs at a frequency of 1251 MHz on this specific model. It features 3584 SPUs along with 224 Texture Address Units and 96 ROPs.
Compare those specifications to the Radeon R9 290, which features clock speeds of 800 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Nvidia Titan X should theoretically be a lot better than the Radeon R9 290 in general. (explain)
Texel RateThe Nvidia Titan X will be quite a bit (more or less 148%) more effective at AF than the Radeon R9 290. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Nvidia Titan X is a better choice, and very much so. (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 information (measured in MB per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
