	Difference: 229 Watts (382%)

Memory Bandwidth

In theory, the GeForce GTX 295 will be 250% quicker than the GeForce GTX 965M in general, due to its higher data rate. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 159776 (250%)

Texel Rate

The GeForce GTX 295 should be much (more or less 53%) better at texture filtering than the GeForce GTX 965M. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 965M		60416 Mtexels/sec
	Difference: 31744 (53%)

Pixel Rate

The GeForce GTX 295 will be a bit (about 7%) more effective at anti-aliasing than the GeForce GTX 965M, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 965M		30208 Mpixels/sec
	Difference: 2048 (7%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
