Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M265 is 25% faster than the GeForce 9500 GT 1GB GDDR3 in general, because of its greater data rate. (explain)

Radeon R7 M265		32000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The Radeon R7 M265 will be a lot (approximately 98%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 8600 (98%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R7 M265 is superior to the GeForce 9500 GT 1GB GDDR3, by a large margin. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 1400 (32%)

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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
