Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 4850 2GB, in theory, should be a lot faster than the Radeon R7 M360 overall. (explain)

Radeon HD 4850 2GB		63552 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 47552 (297%)

Texel Rate

The Radeon R7 M360 should be a little bit (about 8%) faster with regards to anisotropic filtering than the Radeon HD 4850 2GB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 4850 2GB		25000 Mtexels/sec
	Difference: 2000 (8%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 4850 2GB is superior to the Radeon R7 M360, not by a very large margin though. (explain)

Radeon HD 4850 2GB		10000 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 1000 (11%)

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 MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
