Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

The Radeon R9 Fury X comes with a GPU clock speed of 1050 MHz, and the 4096 MB of HBM memory is set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

Compare those specs to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this specific card. It features 4608 SPUs as well as 288 Texture Address Units and 128 Rasterization Operator Units.

Texel Rate

The Radeon RX 6800 XT will be much (more or less 96%) more effective at anisotropic filtering than the Radeon R9 Fury X. (explain)

Radeon RX 6800 XT 525600 Mtexels/sec
Radeon R9 Fury X 268800 Mtexels/sec
Difference: 256800 (96%)

Pixel Rate

The Radeon RX 6800 XT will be much (approximately 248%) more effective at anti-aliasing than the Radeon R9 Fury X, and also 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.

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 in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can 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 Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
