Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

The Radeon R9 Fury X has a clock frequency of 1050 MHz and a HBM memory speed of 500 MHz. It also features a 4096-bit bus, and makes use of a 28 nm design. It is comprised of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

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

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

In theory, the Radeon RX 6800 XT should be a bit faster 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 will be quite a bit (about 96%) faster with regards to texture 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 should be a lot (approximately 248%) better at AA than the Radeon R9 Fury X, and also should be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
