GeForce GTX 1080 vs Radeon RX 5700

Intro

Compare all of that to the Radeon RX 5700, which has a core clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 5700 should theoretically be much better than the GeForce GTX 1080 overall. (explain)

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

Texel Rate

The GeForce GTX 1080 is much (approximately 22%) faster with regards to texture 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 will be a small bit (more or less 10%) better at anti-aliasing than the Radeon RX 5700, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
