GeForce GTX 1080 vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which uses a 7 nm design. AMD has set the core speed at 1465 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 5700 should in theory perform much 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 is a lot (approximately 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

If running with high levels of AA is important to you, then the GeForce GTX 1080 is the winner, but it probably won't make a huge difference. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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