Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M265X should in theory be much superior to the Radeon R7 M360 overall. (explain)

Radeon R9 M265X		72000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R7 M360 is a little bit (more or less 17%) faster with regards to AF than the Radeon R9 M265X. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 4000 (17%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M265X is superior to the Radeon R7 M360, though not by far. (explain)

Radeon R9 M265X		9200 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 200 (2%)

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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
