Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which comes with GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 4608 SPUs, 288 Texture Address Units, and 128 Raster Operation Units.

Radeon R9 Fury X		268800 Mtexels/sec
	Difference: 256800 (96%)

Pixel Rate

The Radeon RX 6800 XT will be much (about 248%) faster with regards to full screen anti-aliasing than the Radeon R9 Fury X, and will be able to handle higher screen resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon R9 Fury X		67200 Mpixels/sec
	Difference: 166400 (248%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
