GeForce RTX 2080 Ti vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which features GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 RAM running at 2250 MHz through a 256-bit bus. It also is made up of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 Ti		250 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 85 Watts (34%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 Ti should be a small bit faster than the Radeon RX 6950 XT in general. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon RX 6950 XT		589824 MB/sec
	Difference: 40960 (7%)

Texel Rate

The Radeon RX 6950 XT should be quite a bit (about 68%) more effective at AF 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

The Radeon RX 6950 XT should be much (more or less 107%) better at FSAA than the GeForce RTX 2080 Ti, and also should be able to handle higher screen resolutions while still performing well. (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 largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type 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 in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated 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 filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
