Theoretically speaking, the GeForce GTX 465 will be 221% faster than the Radeon R7 M265 overall, due to its higher bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 70592 (221%)

Texel Rate

The GeForce GTX 465 will be a lot (about 53%) better at texture filtering than the Radeon R7 M265. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 9308 (53%)

Pixel Rate

The GeForce GTX 465 will be a lot (more or less 235%) better at full screen anti-aliasing than the Radeon R7 M265, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 13624 (235%)

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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 potential to reach the maximum fill rate.
