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

Texel Rate

The Radeon R9 M375 is a lot (about 178%) more effective 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

The Radeon R9 M375 should be quite a bit (approximately 178%) faster with regards to full screen anti-aliasing than the Radeon R7 240, and also capable of handling higher resolutions without losing too much performance. (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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 applied per second. This number is calculated by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
