Radeon R9 Fury X vs Radeon RX 6800 XT

Intro

Compare all of that to the Radeon RX 6800 XT, which comes with 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 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

Theoretically speaking, the Radeon RX 6800 XT should be 2% quicker than the Radeon R9 Fury X in general, because of its greater bandwidth. (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 is a lot (about 96%) better at AF 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 quite a bit (more or less 248%) more effective at AA than the Radeon R9 Fury X, and also should be capable of handling higher screen 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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
