Compare any two graphics cards:
VS

Geforce GTX 1080 Ti vs Radeon RX 6750 XT

Intro

The Geforce GTX 1080 Ti features a GPU core speed of 1480 MHz, and the 11264 MB of GDDR5X memory runs at 1376 MHz through a 352-bit bus. It also is made up of 3584 Stream Processors, 224 Texture Address Units, and 88 Raster Operation Units.

Compare those specs to the Radeon RX 6750 XT, which features GPU clock speed of 2150 MHz, and 12288 MB of GDDR6 memory set to run at 2250 MHz through a 192-bit bus. It also features 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti should perform a bit faster than the Radeon RX 6750 XT overall. (explain)

Geforce GTX 1080 Ti 495616 MB/sec
Radeon RX 6750 XT 442368 MB/sec
Difference: 53248 (12%)

Texel Rate

The Radeon RX 6750 XT should be a bit (about 4%) more effective at anisotropic filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6750 XT 344000 Mtexels/sec
Geforce GTX 1080 Ti 331520 Mtexels/sec
Difference: 12480 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6750 XT is the winner, though only just barely. (explain)

Radeon RX 6750 XT 137600 Mpixels/sec
Geforce GTX 1080 Ti 130240 Mpixels/sec
Difference: 7360 (6%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
