Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 will be 22% quicker than the Radeon R7 240 in general, due to its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 will be much (about 178%) better at AF than the Radeon R7 240. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 26000 (178%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is a better choice, by a large margin. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10400 (178%)

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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
