Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X, in theory, should perform quite a bit faster than the Radeon HD 4350 overall. (explain)

Radeon R9 M385X		96000 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 88000 (1100%)

Texel Rate

The Radeon R9 M385X should be much (about 1239%) more effective at texture filtering than the Radeon HD 4350. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 57000 (1239%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M385X is the winner, by a large margin. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 15300 (665%)

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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 bandwidth is, the lower the ability to reach the max fill rate.
