Exclusive: XBox Next/Xbox 720 chips in production

If you crave more info about the upcoming XBox 720/Next, there is finally some concrete info. The one nice thing about this job is that proud parents like to talk, and that is exactly where this story begins.

If you recall, when we last mentioned the XBox next GPU/GPU/APU chip called Oban, it had just taped out. That was 6 weeks ago or so, and one thing we said in the article was that the devs we queried before that was written all said, “No clue, haven’t heard anything from Microsoft about it yet”. Fair enough, and given the number of them saying the same thing, we rapidly came to the conclusion that there was no info floating. Microsoft had not done any external briefings yet.

So the article went up, and sure enough, in the days between the calls, emails, and door knockings, and when the article went up, MS briefed people. Luckily, Murphy never met Darwin…. Now everyone who should be briefed has been, but no one is talking about it. Darn. That said, they briefed devs almost to the day that the chip taped out, conveniently NDAing them at the same time. Coincidence?

Now for the new stuff. The XBox Next/720 Oban chip is in initial production. Sources at a foundry with a blue logo, confirm that Oban wafers started running in the final days of 2011. Sources on the other side of the continent in Redmond when questioned, said, “Who the f*&$ told you that? I am going to f#*&ing rip someone’s head off”. We at SemiAccurate take this as confirmation that the initial sources were in the right ballpark.

Other sources at Microsoft, conveniently out of head-ripping-off range, said that the initial order was for around 10K wafers, mostly at the aforementioned three letter logo’d company, but a sizeable chunk is being run at Global Foundries too. Again, coincidence? We doubt it.

So, time for a little speculation. Oban is being made by IBM primarily, so that almost definitively puts to bed the idea of an x86 CPU that has been floating. We said we were 99+% sure that the XBox Next/720 is a Power PC CPU plus an ATI GCN/HD7000/Southern Islands GPU, and with this last data point, we are now confident that it is 99.9+%. Why? Several licensing agreements that cover what can be made where will enrich a fleet of lawyers if Oban is x86, but do not preclude the possibility entirely, hence the last .1%.

If you assume the chip is an SoC, and is made on 300mm 32nm SOI wafers, you can come up with a bunch of interesting numbers. Yield on these parts should be pretty high, it is for AMD’s Bulldozer, and those chips run at a much higher speeds on the same process as Oban. If the chip is huge, basically reticle sized at 550-600mm^2, you can expect to get about 100 die candidates per wafer.

With 10K wafers, 100 candidates per, and lowballing yields at 20%, you are looking way way more chips than initially necessary for dev kits. Before you jump up and down about the chances of an XBox 720 under the summer “School’s Out Tree”, these chips are NOT destined for production consoles. You will not get one unless you are in line for a dev kit, or know someone at Microsoft with a penchant for handing out top secret keychains.

This batch, huge though it is, will make the silicon for the initial run of dev kits, and then some. Given the order size, MS seems to be taking no chances on quantity, even Nvidia level yields should provide enough dev kits to go around, so don’t fret if you are in line for one. There will almost assuredly be several revs of Oban before silicon is finalized, that is just the way things are done. The first few of these chips should be coming out of the oven in late February barring any unforeseen problems, so dev kits with real silicon are likely for March, earlier if you are really important.

Sources are still saying to expect silicon production for retail consoles to start late this year, and that guidance won’t change until the first round of volume parts is analyzed late in the quarter. Production for end user consoles isn’t going to start until late 2012, so don’t expect the XBox Next/720 before spring 2013. One thing you can say for sure now is that the console is real now, and the momentum is really picking up.

明年又9000了。。太快了

这个是最起码的，估计也不是零售版的核心，应该会有加强部分。

跳过8000？而且这个架构应该会延续到9000

AMD28nm的良品率还不高，到现在为止看看7970的出货量就知道了，中端的7700/7800系列3月才公布，大量出货至少得是夏季，XBOX720真用7800系列的话那发售时期应该是明年第一季度晚些时候吧

微软和SONY都已经确认本年E3不会有新主机发布，最快也要等到明年E3了

微软什么时候确认本年不公布了？

我只关心售价和发售日

明年发表,后年发布,现在就确定用什么gpu?

绝壁烟雾弹

说的就是2013发表 2014年发售
今年e3没有720和ps4
如果明年要发售没道理今年e3不拿出来

今年e3没有ps4是确定了，没有720是哪里的消息？

另外13公布13发售也很正常啊，360不就是么
