Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon R9 290X
IntroThe GeForce GTX 780 Ti has a clock frequency of 875 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.
Compare those specs to the Radeon R9 290X, which comes with GPU core speed of 800 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 512-bit bus. It also features 2816 Stream Processors, 176 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 780 Ti, in theory, should perform a small bit faster than the Radeon R9 290X overall. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (approximately 49%) better at texture filtering than the Radeon R9 290X. (explain)
Pixel RateThe Radeon R9 290X should be a lot (approximately 22%) faster with regards to anti-aliasing than the GeForce GTX 780 Ti, and also able to handle higher screen 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.
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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units 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 per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
