Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375 should in theory be just a bit superior to the Radeon R7 M265 overall. (explain)

Radeon R9 M375		35200 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 should be a lot (about 133%) more effective at AF than the Radeon R7 M265. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 23200 (133%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M375 is the winner, by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 10440 (180%)

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 moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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