Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Radeon R7 370 2G		110 Watts
	Difference: 4 Watts (4%)

Memory Bandwidth

In theory, the Radeon R7 370 2G will be 87% quicker than the GeForce GT 450 (OEM) overall, because of its higher bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 83200 (87%)

Texel Rate

The Radeon R7 370 2G will be quite a bit (more or less 229%) more effective at AF than the GeForce GT 450 (OEM). (explain)

Radeon R7 370 2G		62400 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 43440 (229%)

Pixel Rate

The Radeon R7 370 2G should be a lot (more or less 65%) faster with regards to AA than the GeForce GT 450 (OEM), and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
GeForce GT 450 (OEM)		18960 Mpixels/sec
	Difference: 12240 (65%)

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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
