Geforce GTX 1080 Ti vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which uses a 7 nm design. AMD has set the core frequency at 1700 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this specific card. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 6800 should perform just a bit faster than the Geforce GTX 1080 Ti overall. (explain)

Radeon RX 6800		524288 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 28672 (6%)

Texel Rate

The Radeon RX 6800 will be much (more or less 23%) faster with regards to texture filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
Geforce GTX 1080 Ti		331520 Mtexels/sec
	Difference: 76480 (23%)

Pixel Rate

The Radeon RX 6800 should be quite a bit (approximately 25%) more effective at FSAA than the Geforce GTX 1080 Ti, and also should be capable of handling higher resolutions better. (explain)

Radeon RX 6800		163200 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 32960 (25%)

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 information (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write 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 clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
