Intel LGA-1156 thread.

Intel's new CPU's are expected early September. They will be in a new socket (LGA-1156). I'm excited to see the i7 860s, even though it will be out at a price above my range, I'm hoping it will drop not long after. Looks like this socket update will be an interesting update for HTPC's.

Glad to see Thermaltake will make my favorite CPU cooler for HTPCs the ISGC-100 available for LGA-1156 (looks like they will offer a bracket that will allow both LGA-1366 and LGA-1156), as well as others later this month. http://www.techpowerup.com/img/09-07-13/1a.jpg


Here's a great site with a bunch of info. on coolers and motherboards on this subject:

Just bumping this. Surprised not to see others interested in Intel's new CPUs/socket. The Core i7 860s (and perhaps the 850s?) looks good to me. LGA-1156 released in 5 weeks.
I'll probably build a PC based on the 1156 architecture late next year. By then, there should be nicely priced CPUs available that will really demolish my current C2Q-based chip.


The current rollout of 1156 motherboards do look nice.
What do you want to know? Hopefully this intersects with what I am allowed to talk about.
Any info. about the i7 that's clocked at 2.4GHz (850?)? Is it just a lower clocked 860 or will there be other differences?


How about some info. on Core i5 and i3?
I can't be sure, as the specifics about what each model number does are not available to me, but it's my understanding from what I've seen on the web that the Core i7 9xx models are Bloomfield-based (1366), and the Core i7 8xx models are Lynnfield-based (1156). Within those categories, generally speaking, the only differences should be clock speed and turbo speeds.
Unfortunately, Intel employees outside of the marketing group are going to be very tight lipped about it until the NDAs are lifted. Anyone interested should look at third party articles around the web, as there are more than a few, that show pretty close performance between the whole set. Something to note though is that the i7 on 1366 will likely perform worse in encoding because of the lesser turbo states and the need for tripple channel memory just isn't there. The i5s however are likely to take a notable performance hit due to the lack of hyperthreading. I'll be looking for the i7 850 or 860 for sure!

What TDP does these things have?

That won't be released until the NDA is up and the chips themselves are officially released, but given that they're 45nm products I would expect dual cores to be available at 65w and/or 90w and quad cores to be available at 130W, possibly 110-115 for lower end quad cores without hyper threading.
I think lower, as the 1156 chips don't have a QPI controller. Now, they will have PCI Express instead. I think i7-1366 is eventually going to be a dead-end. It's a nerfed Xeon platform after all. The platform as a whole is made for multiple CPUs. The only time one would need it is if they wanted to use 3 graphics cards and needed QPI's bandwidth. Of course, I'd imagine 1156 motherboards will eventually have NF200 PCI-E switches, too. The 1366 platform could be the first beneficiary of the 8-core i7...but that depends on Intel...who has an AWEFUL track record of supporting multiple sockets in the consumer market. current 1366 boards may work with Xeon upgrades...possibly.


So, here's a summary of what most believe everything will be:

i7 9xx: 1366, Hyperthreaded, quad core, QPI link to X58

i7 8xx: 1156, Hyperthreaded, quad core, PCI-E

i5: 1156, no HT, quad core (maybe dual too with HT), PCI-E

i3: probably a dual core Nehalem with a GMA graphics die in the package, no HT, PCI-E
Think I read in a link in the link in my first post that the Core i7 860s is expected to have 82W and I think 89W in the regular 860 model.
Its an exciting time to be gearing up to build a new HTPC to be sure ....I for one will be giving these a thrashing. To be fair I would have built a system by now if the MBs were not so expensive, the current i7 chips are pretty reasonable. Looking for big things. The only board I've seen so far is an ASUS P7P55 EVO but it sure looks nice.

Cheers,

Jiff

Socket 1156 is not capable of graphics integrated into the CPU because there are no pathways for video output, the i3's currently announced and for 1156 are just going to be the most basic dual core CPU's in the line-up, equivalent to the current 5x00 or 6x00 series pentium dual cores. For cpu integrated graphics there will have to be yet another socket.
yea, that's why I didn't specify a socket for it



And there may be pathways for video out. We don't know for sure. It only needs 20 pins for that after all.

Check the link in the 1st post, there seems to be some motherboards with onboard video posted.

Not true. 1156 will have both integrated graphics and non-integrated graphics devices.

Here are features of Ibex Peak chipsets. All support Lynnfield and Clarkdale (IGP version). It's "Flexible Display Interface (FDI)" that supports GPU (not sure if this is the official name).

I was miss-informed, and sent a couple e-mails asking for clarification on the previous information I had received about clarkdale. It's possible that the information I was going on is on release only or on P55 only(my guess).


Oh, and I keep hearing conflicting reports as to whether or not braidwood(onboard slot for NAND memory) will be supported on P55 or not, I've seen boards from just about every major manufacturer that has a slot on it, most of which have P55 screened right on them.
I was planning on building an 1156 system early next year to replace my aging HTPC, however since that system was having some boot drive flakiness I decided pull the trigger in a G45 based DG45ID.


I will be looking for the lowest power cpu+motherboard with "on package graphics" (did I just invent a new term?). As soon as I can build a mini ITX for

I am really hoping to see an 1156 version of the DG45FC motherboard that is even better than the original.

Well, you definitely fail to mention that the 6 Core Gulftowns are coming to 1366.. 1366 is definitely going to be the enthusiast socket, as is the case now, and if I were building a Core system for a HTPC, i'd wait until 1156 is released.
