Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should theoretically be quite a bit superior to the Radeon HD 4730 in general. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M370X will be much (about 43%) more effective at AF than the Radeon HD 4730. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 9600 (43%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M370X is the winner, by far. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 7200 (129%)

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 max amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
