Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon HD 3850 512MB will be 231% faster than the Radeon R7 M360 overall, due to its higher bandwidth. (explain)

Radeon HD 3850 512MB		52992 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 36992 (231%)

Texel Rate

The Radeon R7 M360 should be much (approximately 153%) better at anisotropic filtering than the Radeon HD 3850 512MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 3850 512MB		10688 Mtexels/sec
	Difference: 16312 (153%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 3850 512MB is superior to the Radeon R7 M360, though not by far. (explain)

Radeon HD 3850 512MB		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should 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 AA, HDR and high resolutions.

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

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