In theory, the Radeon R9 M295X is 19% faster than the Radeon RX 6500 XT overall, because of its greater data rate. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 28544 (19%)

Texel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 47%) faster with regards to texture filtering than the Radeon R9 M295X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 44800 (47%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 193%) faster with regards to full screen anti-aliasing than the Radeon R9 M295X, and will be able to handle higher resolutions more effectively. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 46400 (193%)

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 (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
