GeForce RTX 2080 Ti vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which comes with a clock frequency of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Radeon RX 6950 XT		589824 MB/sec
	Difference: 40960 (7%)

Texel Rate

The Radeon RX 6950 XT should be quite a bit (more or less 68%) more effective at anisotropic filtering than the GeForce RTX 2080 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce RTX 2080 Ti		367200 Mtexels/sec
	Difference: 248800 (68%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6950 XT is the winner, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce RTX 2080 Ti		118800 Mpixels/sec
	Difference: 127600 (107%)

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 in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
