Geforce GTX 1080 Ti vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which comes with clock speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 memory. 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 GTX 1080 Ti		250 Watts
Radeon RX 6950 XT		335 Watts
	Difference: 85 Watts (34%)

Memory Bandwidth

Theoretically, the Radeon RX 6950 XT should perform a small bit faster than the Geforce GTX 1080 Ti overall. (explain)

Radeon RX 6950 XT		589824 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 94208 (19%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (more or less 86%) more effective at anisotropic filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 284480 (86%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6950 XT is the winner, by a large margin. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 116160 (89%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
