The Sandy Bridge Preview
by Anand Lal Shimpi on August 27, 2010 2:38 PM ESTThe Roadmap & Pricing
I’ve defined the launch parts earlier in this article, but now I’m going to put them in perspective. When Intel provides its partners with roadmaps it also provides them with an idea of where future CPUs slot into various segments/price points. For example, Intel’s LGA-1366 roadmap tell us that in the “Extreme” market segment Intel only has a single product offering: the Core i7 980X. And in Q1 2011 the 980X gets replaced by the 990X.
Usually based on this information you can get a general idea of how much future products will cost - or at least what they will be comparable to. In this example the 990X will most likely be priced at whatever the 980X is priced at. Products may change, but the price people are willing to pay in a certain market segment usually doesn’t.
What we have below is the Intel roadmap, with Sandy Bridge included, for Q3 2010 through Q3 2011. The further out you go in a roadmap the lower your accuracy becomes, so I wouldn’t worry too much about us not seeing LGA-2011 on there yet.
It’s based on this roadmap that I mentioned some pricing earlier. If all stays the same, the Core i7 2600K will take the place of the Core i7 950, currently priced at $562. The 2600 will fit somewhere around the 680 and 875K ($342) and the 2500K will replace the i5 760/655K ($205 - $216).
The cheapest Sandy Bridge at launch will be the Core i3 2100, which will replace the i3 560 at around $138.
Now pricing is always a huge variable, but I have to say, based on the performance you’re about to see - these parts would be priced right.

The GPU is on the same die, So depending on what you mean by true "Fusion" product. It is by AMD's definition ( the creator of the tech terms "Fusion" ) a fusion product.iwodo - Sunday, August 29, 2010 - link
You get 10% of IPC on average. It varies widely from 5 % to ~30% clock per clock.None of these Test have had AVX coded. I am not sure if you need to recompile to take advantage of the additional width for faster SSE Code. ( I am thinking such changes in coding of instruction should require one. ) AVX should offer some more improvement in many areas.
So much performance is here with even less Peak Power usage. If you factor in the Turbo Mode, Sandy Bridge actually give you a huge boost in Performance / Watts!!!
So i dont understand why people are complaining.

Yes AVX requires software changes, as well as OS support for using XSAVE to save AVX state.BD2003 - Sunday, August 29, 2010 - link
It sounds like intel has a home run here. At least for my needs. Right now I'm running entirely on core 2 chips, but I can definitely find a use for all these.For my main/gaming desktop, the quad core i5s seem like theyll be the first upgrade thats big enough to move me away from my e6300 from 4 years ago.
For my HTPC, the integrated graphics seem like theyre getting to a point where I can move past my e2180 + 9400 IGP. I need at least some 3d graphics, and the current i3/i5 don't cut it. Even lower power consumption + faster CPU, all in a presumably smaller package - win.
For my home server, I'd love to put the lowest end i3 in there for great idle power consumption but with the speed to make things happen when it needs to. I'd been contemplating throwing in a quad core, but if the on-die video transcoding engine is legitimate there will be no need for that.
Thats still my main unanswered question: what's the deal with the video encoder/transcoder? Does it require explicit software support, or is it compatible with anything that's already out there? I'm mainly interested in real time streaming over LAN/internet to devices such as an ipad or even a laptop - if it can put out good quality 720-1080p h264 at decent bitrates in real time, especially on a low end chip, I'll be absolutely blown away. Any more info on this?

I do understand some complains, but Intel is running a business and so they do what is in their best interest.Yet, concerning USB 3 it seems to be too much of a disservice to the costumers that it should be in, without any third party add-on chip!
I think it is shameful of them to delay this further just so that they can get their LightPeak thing into to the market. Of which I read nothing in this review so I wonder, when will even that one come?!
I can only hope AMD does support it (haven't read about it) and they start getting more market, maybe that will show these near sighted Intel guys.

Lightpeak would be chipset functionality, at least at first.Also, lightpeak is not a protocol, it's protocol-agnostic, and can in fact carry USB 3.0.
But, rant away if you want...

I'm really interested to see how Intel is going to price the higher of these new CPU's, as there are several hurdles:1) The non-K's are going up against highly overclockable 1366 and 1156 parts. So pricing the K-models too high could mean trouble.
2) The LGA-1356 platform housing the new consumer high-end(LGA-2011 will be server-only) will also arrive later in 2011. Since these are expected to have up to 8 cores, pricing the higher 1155 CPU's too high will force a massive price-drop when 1356 arrives.(Or the P67 platform will collapse.) And 1366 has shown that such a high-end platform needs the equivalent of an i7 920 to be successful. So pricing the 2600K @ $500 seems impossible. Even $300 would not leave room for a $300 1356 part as that will, with 6-8 cores, easily outperform the 2600K.
It will also be quite interesting to see the development of those limits on overclocking when 1356 comes out. As imposing limits there too, could make the entire platform fail.(OCed 2600K better then 6-core 1356 CPU for example.) And of course AMD's response to all this. Will they profit from the overclocking limits of Intel? Will they grab back some high-end? Will they force Intel to change their pricing on 1155/1356?
@Anand:
It would be nice to see another PCIe 2.0 x8 SLI/CF bottleneck test with the new HD 6xxx series when the time comes. I'm interested to see if the GPU's will catch up with Intels limited platform choice.

I'm disappointed that you didn't test it against 1366 quads. The triple channel memory and a more powerful platform in general have a significant advantage over 1156, so a lot of us are looking at those CPUs. Especially since the i7 950 is about to have its price reduced.A $1000 six-core 980X doesn't really fit in there, since it's at a totally different price point.
I was all for the 1366 as my next upgrade, but the low power consumption of Sandy Bridge looks very promising in terms of silent computing (less heat).

What do you think the Core i7 980x uses? An LGA 1366 socket with triple channel memory support. So what makes you think that the Core i7 950 is going to perform any diff?????
