Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M265 should be 25% quicker than the GeForce 9500 GT 512MB GDDR3 overall, because of its higher data rate. (explain)

Radeon R7 M265		32000 MB/sec
GeForce 9500 GT 512MB GDDR3		25600 MB/sec
	Difference: 6400 (25%)

Texel Rate

The Radeon R7 M265 is much (approximately 98%) faster with regards to AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce 9500 GT 512MB GDDR3		8800 Mtexels/sec
	Difference: 8600 (98%)

Pixel Rate

The Radeon R7 M265 is a lot (approximately 32%) more effective at anti-aliasing than the GeForce 9500 GT 512MB GDDR3, and should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce 9500 GT 512MB 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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