Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 370 2G is 1144% faster than the Radeon R5 M330 overall, due to its greater data rate. (explain)

Radeon R7 370 2G		179200 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R7 370 2G will be much (about 203%) better at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 41800 (203%)

Pixel Rate

The Radeon R7 370 2G should be quite a bit (about 279%) more effective at AA than the Radeon R5 M330, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R5 M330		8240 Mpixels/sec
	Difference: 22960 (279%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.
