GeForce RTX 3080 12 GB vs Radeon R9 Fury X

Intro

Compare all of that to the Radeon R9 Fury X, which comes with a GPU core clock speed of 1050 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also features 4096 Stream Processors, 256 TAUs, and 64 Raster Operation Units.

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon R9 Fury X		512000 MB/sec
	Difference: 422298 (82%)

Texel Rate

The GeForce RTX 3080 12 GB is much (about 31%) better at anisotropic filtering than the Radeon R9 Fury X. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon R9 Fury X		268800 Mtexels/sec
	Difference: 84000 (31%)

Pixel Rate

The GeForce RTX 3080 12 GB should be much (more or less 110%) faster with regards to FSAA than the Radeon R9 Fury X, and should be able to handle higher screen resolutions while still performing well. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon R9 Fury X		67200 Mpixels/sec
	Difference: 73920 (110%)

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 data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 in one second. This figure is worked out by multiplying the total amount of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
