GeForce RTX 2070 vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which comes with GPU core speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 5120 Stream Processors, 320 TAUs, and 128 ROPs.

GeForce RTX 2070		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT should be much (approximately 188%) more effective at AF than the GeForce RTX 2070. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 380960 (188%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, by a large margin. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 143360 (159%)

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 information (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
