Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 360, in theory, should be just a bit faster than the Radeon R9 M380 in general. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 360 will be a lot (more or less 26%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 10400 (26%)

Pixel Rate

The Radeon R7 360 is just a bit (approximately 5%) faster with regards to AA than the Radeon R9 M380, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 800 (5%)

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 max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
