Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 295 is 536% quicker than the Radeon R9 M375 in general, because of its higher data rate. (explain)

GeForce GTX 295		223776 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 188576 (536%)

Texel Rate

The GeForce GTX 295 will be a lot (about 127%) faster with regards to anisotropic filtering than the Radeon R9 M375. (explain)

GeForce GTX 295		92160 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 51560 (127%)

Pixel Rate

The GeForce GTX 295 is a lot (approximately 99%) more effective at AA than the Radeon R9 M375, and should be able to handle higher screen resolutions better. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon R9 M375		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.

Price Comparison

Specifications

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

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

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