Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

Compare that to the Radeon RX 6800 XT, which comes with a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is made up of 4608 SPUs, 288 TAUs, and 128 Raster Operation 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

Theoretically speaking, the Radeon RX 6800 XT should be just a bit faster than the Radeon R9 Fury X overall. (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 much (more or less 96%) better at 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 is a lot (more or less 248%) more effective at FSAA 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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
