That last point is important. They’re both 14-nanometer products for us, so it doesn’t change our factory profile, and just generally, the faster we bring out new features and cool stuff to the market, the better off we are. So, we are not planning to slowdown Skylake, if that was at the heart of your question.
Ross Seymore, Deutsche Bank
Thank you.

The next question comes from CJ Muse from Evercore ISI.
CJ Muse, Evercore ISI
Thank for taking my question. I guess, first question, Brian, I wanted to, I guess, clarify a comment you made earlier. I think you said that you were driving $800 million out of the business in mobility in 2015, including reorg to drive efficiencies, and I guess my question here is: does that include also the benefit of lower contra revenues?
Brian Krzanich, Chief Executive Officer
Yes.
Stacy Smith, Chief Financial Officer
That’s an all-in number.
Brian Krzanich, Chief Executive Officer
It’s the efficiencies we’ll gain from the organizational structure. You know, we are doing continued – just I’ll call it –fundamental cost reduction, getting the right P mix in there, reducing the board count, board layers, that kind of – I’ll call basic engineering and the introduction, the increased percentage of Bay Trail cost reduction at the beginning, and then introduction of SoFIA in the second half, which has no contra revenue, so you’ve put all of those together, and they will add up to that $800 million.
Stacy Smith, Chief Financial Officer
And the ramp of LTE.
CJ Muse, Evercore ISI
Great, and then, I guess, as my follow-up, can you provide some additional color on the Rockchip and Spreadtrum side – would love to hear what milestones perhaps we should be watching for?
Brian Krzanich, Chief Executive Officer
You know, I think, let’s start with Rockchip. On Rockchip, we’ve actually been working with them on their first design, it’s an enhancement to the 3G – so it’s SoFIA 3GR and you’ll see it. It’s got some enhancements to the graphics and some other functionality. I think you’ll see that in 2015. They have already got their first silicon out. You’ll have to go talk to them – again part of it is – they have a certain level of independence. They are going to ramp and launch that product when they feel ready but, you know, the first silicon is out, and going out there validation and certification, so we’re right on schedule. I’d say actually we’re slightly ahead of schedule with Rockchip. We’ll continue to bring designs, and next we’ll move to LTE just like ours, and then keep moving on, just right in line with ours, just a little bit, maybe, a quarter or two after our exemplary product as well.
From Spreadtrum, that deal close more in the second half of the year. We’ve started to work with them with the product definitions done, we’re working on exactly what their SoFIA will look like, and we’ll progress through that through this year but the relationship and the model of having them produce SoFIA derivatives with additional features or additional capabilities targeted toward their specific market and channels is exactly the same methodology that we’ll take.
CJ Muse, Evercore ISI
Very helpful. Thank you.
Stacy Smith, Chief Financial Officer
Thanks, CJ. Operator, we will go ahead and take two more questions, please.

The next question comes from Matt Ramsay from Canaccord Genuity.
Matt Ramsay, Canaccord Genuity
Thank you very much for taking my question. Brian, I wanted to ask on DCG. Obviously a really big quarter in December, up about $1 billion dollars from the March quarter. You talked a bit about it being lumpy with the cloud customers, maybe you can talk about what part of that big jump in revenue from September to December was from first-time purchases of Grantley, and I guess the longer term question I’m asking is the health of the enterprise server market relative to some weaker trends we saw earlier in the year and the recovery in the back half of 2014. Thanks.
Stacy Smith, Chief Financial Officer
This is Stacy, we aren’t going to get that granular, I don’t think, In terms of the break out of the DCG revenue, I would say what we saw in Q-4 was: we saw strength in enterprise and then we continued to see those robust growth rates in cloud and networking and data analytics. Beyond that, I’m not going to break it out.
