GeForce GTX 980 Ti vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which has core clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 590		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The Radeon RX 590 should be just a bit (approximately 20%) faster with regards to texture filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 35536 (20%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980 Ti is superior to the Radeon RX 590, and very much so. (explain)

GeForce GTX 980 Ti		96000 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 48992 (104%)

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 (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
