Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 370 4G should in theory be quite a bit superior to the Radeon R5 M330 in general. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon R5 M330		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R7 370 4G should be much (approximately 203%) more effective at anisotropic filtering than the Radeon R5 M330. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon R5 M330		20600 Mtexels/sec
	Difference: 41800 (203%)

Pixel Rate

The Radeon R7 370 4G is quite a bit (about 279%) faster with regards to full screen anti-aliasing than the Radeon R5 M330, and capable of handling higher screen resolutions better. (explain)

Radeon R7 370 4G		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 (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 amount of pixels that the graphics chip 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 Raster Operations Pipelines by the clock 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
