GeForce GTX 1080 vs Radeon RX 6800

Intro

Compare that to the Radeon RX 6800, which has core speeds of 1700 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 RAM. It features 3840 SPUs as well as 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1080		180 Watts
Radeon RX 6800		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 should be a lot faster than the GeForce GTX 1080 overall. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 196608 (60%)

Texel Rate

The Radeon RX 6800 should be quite a bit (more or less 59%) more effective at AF than the GeForce GTX 1080. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 150880 (59%)

Pixel Rate

The Radeon RX 6800 will be quite a bit (about 59%) faster with regards to full screen anti-aliasing than the GeForce GTX 1080, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 60352 (59%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
