Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 280 will be 1567% faster than the GeForce 930M in general, because of its higher data rate. (explain)

Radeon R9 280		240000 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 225600 (1567%)

Texel Rate

The Radeon R9 280 is much (about 369%) better at AF than the GeForce 930M. (explain)

Radeon R9 280		104496 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 82224 (369%)

Pixel Rate

The Radeon R9 280 will be a lot (more or less 302%) better at full screen anti-aliasing than the GeForce 930M, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 280		29856 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 22432 (302%)

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 (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock 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 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record 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 clock 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 output 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 ability to reach the max fill rate.
