GeForce GTS 150		141 Watts
GeForce GTX 465		200 Watts
	Difference: 59 Watts (42%)

Memory Bandwidth

In theory, the GeForce GTX 465 will be 221% faster than the GeForce GTS 150 overall, due to its greater bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 70592 (221%)

Texel Rate

The GeForce GTS 150 will be a lot (more or less 77%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 20652 (77%)

Pixel Rate

The GeForce GTX 465 is much (more or less 64%) better at AA than the GeForce GTS 150, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 7584 (64%)

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 largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
