Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 450 (OEM) is 33% quicker than the Radeon R9 M375X overall, because of its higher bandwidth. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The Radeon R9 M375X should be much (more or less 114%) faster with regards to anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 21640 (114%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 450 (OEM) is the winner, though not by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 2720 (17%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
