Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6800		250 Watts
Radeon R9 Fury X		275 Watts
	Difference: 25 Watts (10%)

Memory Bandwidth

In theory, the Radeon RX 6800 will be 2% faster than the Radeon R9 Fury X overall, because of its higher bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
Radeon R9 Fury X		512000 MB/sec
	Difference: 12288 (2%)

Texel Rate

The Radeon RX 6800 is quite a bit (about 52%) more effective at AF than the Radeon R9 Fury X. (explain)

Radeon RX 6800		408000 Mtexels/sec
Radeon R9 Fury X		268800 Mtexels/sec
	Difference: 139200 (52%)

Pixel Rate

The Radeon RX 6800 will be quite a bit (approximately 143%) more effective at anti-aliasing than the Radeon R9 Fury X, and also should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6800		163200 Mpixels/sec
Radeon R9 Fury X		67200 Mpixels/sec
	Difference: 96000 (143%)

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 MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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