Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTS 450 1GB is 80% quicker than the Radeon R7 M265 in general, because of its higher data rate. (explain)

GeForce GTS 450 1GB		57728 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 25728 (80%)

Texel Rate

The GeForce GTS 450 1GB should be quite a bit (about 44%) better at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTS 450 1GB		25056 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 7656 (44%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is superior to the Radeon R7 M265, and very much so. (explain)

GeForce GTS 450 1GB		12528 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 6728 (116%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 bandwidth is, the lower the ability to get to the max fill rate.
