Radeon RX 590		262144 MB/sec
	Difference: 720896 (275%)

Texel Rate

The Radeon RX 7900 XTX is quite a bit (more or less 237%) more effective at anisotropic filtering than the Radeon RX 590. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 500784 (237%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 7900 XTX is the winner, and very much so. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 309152 (658%)

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 data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
