Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 280 should in theory be much superior to the Radeon R9 M375X in general. (explain)

GeForce GTX 280		141696 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 69696 (97%)

Texel Rate

The GeForce GTX 280 is just a bit (more or less 19%) more effective at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 280		48160 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 7560 (19%)

Pixel Rate

The GeForce GTX 280 should be just a bit (approximately 19%) faster with regards to anti-aliasing than the Radeon R9 M375X, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 280		19264 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 3024 (19%)

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 moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
