Radeon R9 Fury X vs Radeon RX 6800

Intro

The Radeon R9 Fury X uses a 28 nm design. AMD has clocked the core speed at 1050 MHz. The HBM memory works at a speed of 500 MHz on this specific model. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Compare those specifications to the Radeon RX 6800, which has a clock speed of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It features 3840 SPUs, 240 Texture Address Units, and 96 ROPs.

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 should be 2% faster than the Radeon R9 Fury X overall, due to its greater data rate. (explain)

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

Texel Rate

The Radeon RX 6800 should be a lot (approximately 52%) more effective at anisotropic filtering 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

If running with high levels of AA is important to you, then the Radeon RX 6800 is the winner, and very much so. (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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If 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 applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better 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 maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
