Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 230 is 20% quicker than the Radeon R7 M265 overall, due to its higher data rate. (explain)

GeForce GT 230		38400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The Radeon R7 M265 is a lot (approximately 98%) faster with regards to AF than the GeForce GT 230. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 8600 (98%)

Pixel Rate

The Radeon R7 M265 should be much (about 32%) better at AA than the GeForce GT 230, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 230		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 information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 the graphics card could possibly write 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many 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.
