In theory, the Radeon RX 7900 XTX should perform much faster than the Radeon RX 6750 XT overall. (explain)

Radeon RX 7900 XTX		983040 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 540672 (122%)

Texel Rate

The Radeon RX 7900 XTX should be a lot (more or less 107%) more effective at AF than the Radeon RX 6750 XT. (explain)

Radeon RX 7900 XTX		712320 Mtexels/sec
Radeon RX 6750 XT		344000 Mtexels/sec
	Difference: 368320 (107%)

Pixel Rate

The Radeon RX 7900 XTX is quite a bit (more or less 159%) more effective at FSAA than the Radeon RX 6750 XT, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 7900 XTX		356160 Mpixels/sec
Radeon RX 6750 XT		137600 Mpixels/sec
	Difference: 218560 (159%)

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 data (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
