Radeon R9 Fury X		512000 MB/sec
	Difference: 471040 (92%)

Texel Rate

The Radeon RX 7900 XTX should be a lot (approximately 165%) more effective at texture filtering than the Radeon R9 Fury X. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon R9 Fury X		268800 Mtexels/sec
	Difference: 443520 (165%)

Pixel Rate

The Radeon RX 7900 XTX is much (approximately 430%) faster with regards to full screen anti-aliasing than the Radeon R9 Fury X, and should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon R9 Fury X		67200 Mpixels/sec
	Difference: 288960 (430%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
