GeForce RTX 2080 Ti vs Radeon RX 6700 XT

Intro

The GeForce RTX 2080 Ti makes use of a 12 nm design. nVidia has clocked the core frequency at 1350 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this card. It features 4352 SPUs as well as 272 Texture Address Units and 88 Rasterization Operator Units.

Compare that to the Radeon RX 6700 XT, which has a clock speed of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 192-bit memory bus, and uses a 7 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6700 XT 230 Watts
GeForce RTX 2080 Ti 250 Watts
Difference: 20 Watts (9%)

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti is 60% faster than the Radeon RX 6700 XT in general, because of its greater bandwidth. (explain)

GeForce RTX 2080 Ti 630784 MB/sec
Radeon RX 6700 XT 393216 MB/sec
Difference: 237568 (60%)

Texel Rate

The Radeon RX 6700 XT should be a small bit (more or less 1%) better at anisotropic filtering than the GeForce RTX 2080 Ti. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
GeForce RTX 2080 Ti 367200 Mtexels/sec
Difference: 4160 (1%)

Pixel Rate

The Radeon RX 6700 XT should be much (about 25%) faster with regards to FSAA than the GeForce RTX 2080 Ti, and able to handle higher resolutions while still performing well. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
GeForce RTX 2080 Ti 118800 Mpixels/sec
Difference: 29744 (25%)

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.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
