GeForce RTX 2070 vs Radeon RX 7900 XT

Intro

Compare those specs to the Radeon RX 7900 XT, which has a clock speed of 1500 MHz and a GDDR6 memory speed of 2500 MHz. It also uses a 320-bit memory bus, and makes use of a 5 nm design. It is made up of 5376 SPUs, 336 Texture Address Units, and 192 ROPs.

GeForce RTX 2070		458752 MB/sec
	Difference: 360448 (79%)

Texel Rate

The Radeon RX 7900 XT is a lot (more or less 148%) more effective at AF than the GeForce RTX 2070. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 300960 (148%)

Pixel Rate

The Radeon RX 7900 XT is much (more or less 219%) more effective at FSAA than the GeForce RTX 2070, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 197760 (219%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses 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 better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
