GeForce GTX 780 Ti vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which comes with core speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX 780 Ti is 28% quicker than the Radeon RX 590 in general, because of its higher bandwidth. (explain)

GeForce GTX 780 Ti		336000 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The Radeon RX 590 should be a little bit (more or less 1%) better at texture filtering than the GeForce GTX 780 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 780 Ti		210000 Mtexels/sec
	Difference: 1536 (1%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 590 is the winner, but only just. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 5008 (12%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
