GeForce GTS 150		32000 MB/sec
	Difference: 160000 (500%)

Texel Rate

The Geforce GTX 670 should be much (more or less 116%) faster with regards to anisotropic filtering than the GeForce GTS 150. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 55120 (116%)

Pixel Rate

The Geforce GTX 670 should be a lot (more or less 147%) more effective at FSAA than the GeForce GTS 150, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 17440 (147%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
