Radeon RX 5700		180 Watts
GeForce GTX 580		244 Watts
	Difference: 64 Watts (36%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 will be 138% quicker than the GeForce GTX 580 in general, because of its higher bandwidth. (explain)

Radeon RX 5700		458752 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 266368 (138%)

Texel Rate

The Radeon RX 5700 should be much (approximately 327%) faster with regards to texture filtering than the GeForce GTX 580. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 161552 (327%)

Pixel Rate

The Radeon RX 5700 should be quite a bit (approximately 153%) faster with regards to anti-aliasing than the GeForce GTX 580, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce GTX 580		37056 Mpixels/sec
	Difference: 56704 (153%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
