GeForce RTX 2080 Ti vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which features a core clock speed of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 3840 SPUs, 240 TAUs, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 2080 Ti should in theory be a bit faster than the Radeon RX 6800 overall. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 6800		524288 MB/sec
	Difference: 106496 (20%)

Texel Rate

The Radeon RX 6800 should be just a bit (approximately 11%) faster with regards to AF than the GeForce RTX 2080 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 40800 (11%)

Pixel Rate

The Radeon RX 6800 should be quite a bit (more or less 37%) faster with regards to full screen anti-aliasing than the GeForce RTX 2080 Ti, and able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 44400 (37%)

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 maximum 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 interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most 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 amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
