Radeon RX 6800 XT vs Radeon VII

Intro

Compare all of that to the Radeon VII, which comes with a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 memory running at 1000 MHz through a 4096-bit bus. It also is made up of 3840 Stream Processors, 240 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon VII		295 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 5 Watts (2%)

Memory Bandwidth

In theory, the Radeon VII should be much faster than the Radeon RX 6800 XT in general. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 6800 XT		524288 MB/sec
	Difference: 524288 (100%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (more or less 56%) more effective at anisotropic filtering than the Radeon VII. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 189600 (56%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is the winner, and very much so. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 144000 (161%)

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 (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
