Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti has a core clock frequency of 875 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.
Compare that to the Radeon R9 290X, which makes use of a 28 nm design. ATi has set the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific model. It features 2816 SPUs as well as 176 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 780 Ti is 5% quicker than the Radeon R9 290X overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 780 Ti is much (approximately 49%) more effective at AF than the Radeon R9 290X. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 290X is superior to the GeForce GTX 780 Ti, 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 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, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant 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.
