Geforce GTX 1080 Ti vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has set the core speed at 1605 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Geforce GTX 1080 Ti		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

In theory, the Geforce GTX 1080 Ti should be a bit faster than the Radeon RX 5700 XT overall. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 36864 (8%)

Texel Rate

The Geforce GTX 1080 Ti should be a lot (more or less 29%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 74720 (29%)

Pixel Rate

The Geforce GTX 1080 Ti should be quite a bit (approximately 27%) more effective at full screen anti-aliasing than the Radeon RX 5700 XT, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 27520 (27%)

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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to reach the max fill rate.
