Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 360		100 Watts
GeForce GT 450 (OEM)		106 Watts
	Difference: 6 Watts (6%)

Memory Bandwidth

In theory, the Radeon R7 360 will be 8% faster than the GeForce GT 450 (OEM) in general, because of its higher bandwidth. (explain)

Radeon R7 360		104000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 360 will be a lot (about 166%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 31440 (166%)

Pixel Rate

The GeForce GT 450 (OEM) will be a small bit (more or less 13%) more effective at AA than the Radeon R7 360, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 360		16800 Mpixels/sec
	Difference: 2160 (13%)

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 data (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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