GeForce RTX 2080 Ti vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which comes with GPU core speed of 1605 MHz, and 8096 MB of GDDR6 memory running at 1750 MHz through a 256-bit bus. It also is comprised 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 will be much (about 43%) better at 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 will be a little bit (more or less 16%) more effective at AA than the Radeon RX 5700 XT, and will be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses 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 can be processed in one second. This is calculated by multiplying the total texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its 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 the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
