Geforce GTX 1080 Ti vs Radeon RX 6950 XT

Intro

Compare those specs to the Radeon RX 6950 XT, which features a clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation 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

The Radeon RX 6950 XT should in theory 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%) faster with regards to 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 superior to the Geforce GTX 1080 Ti, and very much so. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
