Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 450 (OEM) should perform much faster than the Radeon R9 M370X in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The Radeon R9 M370X will be much (approximately 69%) more effective at AF than the GeForce GT 450 (OEM). (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 13040 (69%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GT 450 (OEM) is a better choice, by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 6160 (48%)

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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
