Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 6900 XT should in theory be a lot better than the Radeon R7 M265 overall. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 492288 (1538%)

Texel Rate

The Radeon RX 6900 XT should be quite a bit (more or less 3256%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 566600 (3256%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon R7 M265, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 227800 (3928%)

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 megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
