GeForce RTX 2080 vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which comes with a core clock frequency of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 7 nm design. It features 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

GeForce RTX 2080		215 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 85 Watts (40%)

Memory Bandwidth

Theoretically, the Radeon RX 6900 XT should be a bit faster than the GeForce RTX 2080 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT is quite a bit (approximately 109%) more effective at AF than the GeForce RTX 2080. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 305240 (109%)

Pixel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 141%) faster with regards to full screen anti-aliasing than the GeForce RTX 2080, and capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 136640 (141%)

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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core 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 fill rate is also dependant on quite a few 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.
