Radeon R7 M265		32000 MB/sec
	Difference: 82688 (258%)

Texel Rate

The Radeon RX 550 is much (more or less 102%) better at AF than the Radeon R7 M265. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 17800 (102%)

Pixel Rate

The Radeon RX 550 should be quite a bit (about 203%) more effective at full screen anti-aliasing than the Radeon R7 M265, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 11800 (203%)

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 information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
