GeForce RTX 2080 Ti vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which comes with a clock speed of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Radeon RX 5700 XT		458752 MB/sec
	Difference: 172032 (38%)

Texel Rate

The GeForce RTX 2080 Ti should be a lot (more or less 43%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 110400 (43%)

Pixel Rate

The GeForce RTX 2080 Ti should be a small bit (approximately 16%) more effective at FSAA than the Radeon RX 5700 XT, and also capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 16080 (16%)

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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
