Geforce GTX 1080 Ti vs Radeon RX 6950 XT

Intro

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

Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 94208 (19%)

Texel Rate

The Radeon RX 6950 XT is a lot (about 86%) better 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

The Radeon RX 6950 XT should be quite a bit (about 89%) faster with regards to anti-aliasing than the Geforce GTX 1080 Ti, and will be able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This 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 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 that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
