Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 270 should in theory be a lot superior to the GeForce 930M overall. (explain)

Radeon R9 270		179200 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R9 270 should be much (more or less 223%) more effective at AF than the GeForce 930M. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 49728 (223%)

Pixel Rate

The Radeon R9 270 will be quite a bit (more or less 288%) faster with regards to anti-aliasing than the GeForce 930M, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 21376 (288%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
