GeForce RTX 2080 vs Radeon RX 6700 XT

Intro

Compare those specifications to the Radeon RX 6700 XT, which has a GPU core clock speed of 2321 MHz, and (Unknown) MB of GDDR6 RAM set to run at 2000 MHz through a 192-bit bus. It also is comprised of 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
Radeon RX 6700 XT		230 Watts
	Difference: 15 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 will be 17% faster than the Radeon RX 6700 XT in general, because of its higher bandwidth. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon RX 6700 XT		393216 MB/sec
	Difference: 65536 (17%)

Texel Rate

The Radeon RX 6700 XT will be much (more or less 33%) more effective at anisotropic filtering than the GeForce RTX 2080. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 92600 (33%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6700 XT is superior to the GeForce RTX 2080, and very much so. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 51584 (53%)

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 (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type 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 better 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 applied per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
