Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 3850 256MB, in theory, should be much faster than the Radeon R7 M360 in general. (explain)

Radeon HD 3850 256MB		52992 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 36992 (231%)

Texel Rate

The Radeon R7 M360 should be quite a bit (approximately 153%) better at anisotropic filtering than the Radeon HD 3850 256MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 3850 256MB		10688 Mtexels/sec
	Difference: 16312 (153%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 3850 256MB is superior to the Radeon R7 M360, though only just barely. (explain)

Radeon HD 3850 256MB		10688 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 1688 (19%)

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 information (measured in 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. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
