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 RAM runs at a speed of 500 MHz on this specific model. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Compare those specifications to the Radeon RX 6800, which makes use of a 7 nm design. AMD has clocked the core speed at 1700 MHz. The GDDR6 memory works at a speed of 2000 MHz on this card. It features 3840 SPUs along with 240 Texture Address Units and 96 Rasterization Operator Units.

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 a bit faster than the Radeon R9 Fury X in general. (explain)

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

Texel Rate

The Radeon RX 6800 is much (more or less 52%) faster with regards to texture 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 using high levels of AA is important to you, then the Radeon RX 6800 is a better choice, 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
