Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 450 (OEM)		106 Watts
Radeon R7 260X		115 Watts
	Difference: 9 Watts (8%)

Memory Bandwidth

Theoretically, the Radeon R7 260X should perform just a bit faster than the GeForce GT 450 (OEM) in general. (explain)

Radeon R7 260X		104000 MB/sec
GeForce GT 450 (OEM)		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 260X is a lot (more or less 225%) better at texture filtering than the GeForce GT 450 (OEM). (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce GT 450 (OEM)		18960 Mtexels/sec
	Difference: 42640 (225%)

Pixel Rate

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

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1360 (8%)

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 MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
