Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

The Radeon R9 Fury X comes with a core clock speed of 1050 MHz and a HBM memory frequency of 500 MHz. It also uses a 4096-bit memory bus, and uses a 28 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 ROPs.

Compare all of that to the Radeon RX 6800 XT, which has core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs along with 288 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Fury X 275 Watts
Radeon RX 6800 XT 300 Watts
Difference: 25 Watts (9%)

Memory Bandwidth

Performance-wise, the Radeon RX 6800 XT should in theory be just a bit better than the Radeon R9 Fury X in general. (explain)

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

Texel Rate

The Radeon RX 6800 XT should be much (about 96%) faster with regards to 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 XT is a better choice, and very much so. (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 maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
