Power Consumption
At idle, the 3960X's power consumption is barely discernible from the 2600K. Under load however, Sandy Bridge E can draw significantly more power. We measured 35% more power draw over a 2600K. The added power consumption makes sense. The chip has more cores and a larger cache, without introducing a more power efficient architecture or a new manufacturing process.

That's what I was doing: blaming AMD. Intel is doing what any company that is interested in making money/profit would do.yankeeDDL - Monday, November 14, 2011 - link
Sorry ... I replied to the wrong post :) I meant to hit the one below!JlHADJOE - Tuesday, November 15, 2011 - link
If you compare it to the extreme edition chip, then Bulldozer looks like good value. But then the 3960X is a halo model for those people who care nothing about price.Considering the 3930K gives you 95% the performance of the 3960X for 50% of the price (see xbitlabs), there's really no reason to get the X-edition chip unless you are building a system purely for bragging rights.
Now when compared to the 3930K, the FX8150 doesn't look nearly as good. If we consider total platform costs with either system having a $300 motherboard and $200 in ram, then we're looking at something in the region of $750 for BD, vs $1000 for the SB-E. +$250 is small change for double the performance at a similar power envelope.

JIHADJOE, yes, that was my point.The 3960X is -arguably- the fastest CPU available, but it is faster by a tiny margin, while being radically more expensive than anything else.
So yes, nothing looks as bad in terms of price/performance ratio, not even the FX8150. And that's, basically, bad for everyone (except Intel)

I agree too AMD's poor Bulldozer performance is having a huge effect on what we can get from Intel and at what price. And I blame AMD not Intel, because Intel or any other company is supposed to do what's best for their company. Heck if Intel did what we want they would probably cause serious harm to AMD. Because it would make AMD even less competitive. And I don't think Intel really wants to put AMD out of business.yankeeDDL - Monday, November 14, 2011 - link

One of the bigger advantages of this platform to me is the 8 DIMM slots. However it was rumored that the first revision of SB-E had/has VT-D problems, which spoils things a little bit as VMs are one of the bigger reasons for lots of RAM. Can you confirm or deny if there are VT-D issues?Anand Lal Shimpi - Monday, November 14, 2011 - link
VT-d is supported, checking to see if there are any functional issues now.Take care,
Anand

ArsTechnica is reporting that VT-D is broken, but they don't cite any sources. A short article explaining what VT-D is for those who don't know and what (if anything) is broken might be in order.Filiprino - Monday, November 14, 2011 - link
That thing is really big!As for Quick Sync, it's not really useful. If you want quality you'll have to use x264, and with lower qualities x264 has some presets that are near as fast as Quick Sync.
The winner combo is LGA2011+Kepler/Souther Islands.
If you have a hole in your pocket you can throw in a dual socket motherboard, some liquid cooling and a big SSD.
