GeForce GTX 1080 vs Radeon RX 5700

Intro

Compare all of that to the Radeon RX 5700, which comes with core clock speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 5700 should theoretically perform a lot faster than the GeForce GTX 1080 in general. (explain)

Radeon RX 5700		458752 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 131072 (40%)

Texel Rate

The GeForce GTX 1080 should be a lot (more or less 22%) faster with regards to anisotropic filtering than the Radeon RX 5700. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 46160 (22%)

Pixel Rate

The GeForce GTX 1080 is just a bit (about 10%) more effective at full screen anti-aliasing than the Radeon RX 5700, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 9088 (10%)

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 maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 is calculated by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
