GeForce GTX 1080 vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which comes with GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 590		175 Watts
GeForce GTX 1080		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

The GeForce GTX 1080 should in theory be a lot faster than the Radeon RX 590 in general. (explain)

GeForce GTX 1080		327680 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 65536 (25%)

Texel Rate

The GeForce GTX 1080 should be quite a bit (approximately 22%) more effective at AF than the Radeon RX 590. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 45584 (22%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1080 is a better choice, by far. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 55840 (119%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the 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 memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
