Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 6770 is 320% faster than the Radeon R7 M360 overall, due to its greater bandwidth. (explain)

Radeon HD 6770		67200 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 51200 (320%)

Texel Rate

The Radeon HD 6770 is quite a bit (approximately 33%) more effective at texture filtering than the Radeon R7 M360. (explain)

Radeon HD 6770		36000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 9000 (33%)

Pixel Rate

The Radeon HD 6770 is quite a bit (approximately 60%) faster with regards to anti-aliasing than the Radeon R7 M360, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 6770		14400 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 5400 (60%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 max fill rate.
