Geforce GTX 1080 Ti vs Radeon RX 5700

Intro

Compare those specs to the Radeon RX 5700, which features a GPU core clock speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti will be 8% quicker than the Radeon RX 5700 overall, due to its higher data rate. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 36864 (8%)

Texel Rate

The Geforce GTX 1080 Ti should be quite a bit (more or less 57%) better at AF than the Radeon RX 5700. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 120560 (57%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 1080 Ti is a better choice, by far. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 36480 (39%)

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 data (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
