Intel Santa Rosa Preview: Centrino V Evolves

Media Encoding - DivX & WME9:
We turned to our DivX and Windows Media Encoder tests to provide a quick look at whether the faster FSB changed media encoding performance all that much:
For the most part, it didn't. Performance remained relatively unchanged between platforms, it looks like the increase in FSB frequency was mostly to enable future higher clock speeds.
3D Rendering - 3ds max 9 & CineBench:
Our final two tests are our 3D rendering favorites: 3ds max 9 and Cinebench 9.5.
Under 3ds max 9 we actually see a decent performance increase due to the faster FSB, over 6%. While it's not huge, it is representative of a situation where the previous Centrino platform was FSB bandwidth limited at current CPU clock speeds.
Cinebench 9.5 gives us a similar result, with an almost 5% performance improvement on the new platform. Once again it's not huge, but it's the biggest performance gain we've seen for the new platform.

I would have thought that the real benefit from Robson would have been the power savings from the ability for the OS to write todisk/save something/do a small amount of swapping without needing to spin up the hard disk.
Regarding performance expectations, what's the read/write throughput on the flash, and is this a fast hard disk? I would expect
reading/writing a large contiguous file to/from a fast hard to be faster than reading/writing to cheap (= slow) flash.
If Vista can store part of the data on the hard disk, and the rest on flash, and read/write both chunks simultaneously
or the flash has throughput as fast/faster as the hard disk then I would hope to see performance benefits.

Maybe it was an interesting article but I cannot read the begining of each line as there are Intel vPro dogs in the way.
