Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX 295 should theoretically be quite a bit better than the Radeon R9 M375X overall. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 151776 (211%)

Texel Rate

The GeForce GTX 295 is much (approximately 127%) better at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 51560 (127%)

Pixel Rate

The GeForce GTX 295 is a lot (more or less 99%) faster with regards to anti-aliasing than the Radeon R9 M375X, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 16016 (99%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
