Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 295X2 is 789% quicker than the Radeon R9 M370X in general, due to its greater bandwidth. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 568000 (789%)

Texel Rate

The Radeon R9 295X2 will be a lot (more or less 1020%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 326336 (1020%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 295X2 is superior to the Radeon R9 M370X, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 117504 (918%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
