Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be 1389% quicker than the Radeon R9 M375 overall, due to its greater data rate. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 489088 (1389%)

Texel Rate

The Radeon RX 6900 XT will be a lot (more or less 1338%) more effective at anisotropic filtering than the Radeon R9 M375. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 543400 (1338%)

Pixel Rate

The Radeon RX 6900 XT will be quite a bit (more or less 1338%) faster with regards to AA than the Radeon R9 M375, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 217360 (1338%)

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 maximum amount of data (measured in megabytes 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. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
