GeForce GTX 970 vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which comes with GPU core speed of 1825 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 5120 Stream Processors, 320 Texture Address Units, and 128 ROPs.

GeForce GTX 970		224000 MB/sec
	Difference: 300288 (134%)

Texel Rate

The Radeon RX 6900 XT will be much (about 435%) faster with regards to AF than the GeForce GTX 970. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 474800 (435%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 166400 (248%)

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: Bandwidth is the max amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 get to the max fill rate.
