GeForce GTX 980 Ti vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which uses a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this card. 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 980 Ti		250 Watts
	Difference: 75 Watts (43%)

Memory Bandwidth

In theory, the GeForce GTX 980 Ti should be 28% faster than the Radeon RX 590 in general, due to its greater bandwidth. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 73856 (28%)

Texel Rate

The Radeon RX 590 should be a small bit (about 20%) more effective at 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

The GeForce GTX 980 Ti will be a lot (approximately 104%) more effective at FSAA than the Radeon RX 590, and also should be capable of handling higher resolutions without slowing down too much. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
