Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M380 should in theory be quite a bit superior to the Radeon HD 4350 overall. (explain)

Radeon R9 M380		96000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 88000 (1100%)

Texel Rate

The Radeon R9 M380 should be much (approximately 770%) more effective at AF than the Radeon HD 4350. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 35400 (770%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M380 is superior to the Radeon HD 4350, and very much so. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 13700 (596%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
