Radeon R7 M360		16000 MB/sec
	Difference: 10496 (66%)

Texel Rate

The Radeon R7 M360 will be much (more or less 153%) faster with regards to texture filtering than the Radeon HD 3690/3830. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 3690/3830		10688 Mtexels/sec
	Difference: 16312 (153%)

Pixel Rate

The Radeon HD 3690/3830 should be a bit (about 19%) more effective at full screen anti-aliasing than the Radeon R7 M360, and also capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 3690/3830		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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has 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 AA, High Dynamic Range and high resolutions.

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

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