GeForce RTX 2070 vs Radeon RX 6700 XT

Intro

Compare those specifications to the Radeon RX 6700 XT, which has a core clock frequency of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 192-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Radeon RX 6700 XT		393216 MB/sec
	Difference: 65536 (17%)

Texel Rate

The Radeon RX 6700 XT will be a lot (about 83%) better at AF than the GeForce RTX 2070. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 168320 (83%)

Pixel Rate

The Radeon RX 6700 XT is much (more or less 65%) more effective at full screen anti-aliasing than the GeForce RTX 2070, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 58304 (65%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
