VS

GeForce RTX 2060 Super vs Radeon RX 6800 XT

Intro

The GeForce RTX 2060 Super features a core clock speed of 1470 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 12 nm design. It features 2176 SPUs, 136 TAUs, and 64 ROPs.

Compare that to the Radeon RX 6800 XT, which has a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 4608 SPUs, 288 TAUs, and 128 ROPs.

GeForce RTX 2060 Super 458752 MB/sec
Difference: 65536 (14%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (about 163%) better at texture filtering than the GeForce RTX 2060 Super. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
GeForce RTX 2060 Super 199920 Mtexels/sec
Difference: 325680 (163%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is a better choice, by a large margin. (explain)

Radeon RX 6800 XT 233600 Mpixels/sec
GeForce RTX 2060 Super 94080 Mpixels/sec
Difference: 139520 (148%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
