GeForce RTX 2070 Super vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular model. It features 5120 SPUs as well as 320 Texture Address Units and 128 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super		215 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 85 Watts (40%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6900 XT should in theory be just a bit better than the GeForce RTX 2070 Super in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce RTX 2070 Super		458752 MB/sec
	Difference: 65536 (14%)

Texel Rate

The Radeon RX 6900 XT will be quite a bit (approximately 127%) faster with regards to texture filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 327200 (127%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce RTX 2070 Super		102720 Mpixels/sec
	Difference: 130880 (127%)

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 (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
