What is Intel's roadmap for 1155?

[tcsenter]

A friend wants me to rebuild his system on a modest budget, I'm eyeing some H77 boards for Socket 1155. Just wondering how long CPUs are going to be shipping for Socket 1155, or whether there will be 4th gen Core processors released for 1155?

If Intel is planning to EOL Socket 1155 within a year or less, then I don't want to go that route. Is Socket 2011 going to always stay the enthusiast platform like X58 and 1366, or is it slated to replace the mainstream segment currently served by 1155 (anytime soon)?? TIA!

If i'm not mistaken IVY Bridge will be be the last 1155 cpus as Haswell will use a new socket ?

 

[ShintaiDK]

Haswell and Broadwell will use LGA1150. Compability is also directly impossible due to the ondie VRM. Not to mention other reasons.

S2011 is much more costly, way behind in technology terms. And will be replaced too. But running SB-E vs Haswell-DT...not pretty.

 

[Denithor]

Socket 1155 ends with this generation.

Socket 2011 will have one further iteration of chips (currently available is SB-based, Intel should launch IB-based chips late this year/early next year). But even 2011 will (have) to be replaced after Ivy because Haswell will not be electrically compatible with this socket (integrated VRMs).

So if you can, wait 6-8 months for Haswell to drop (March to May of next year).

And that's about the end of it!

are they backwards compatible? like can a 1150 cpu fit in a 1155 socket?

No, and how would they be when the LGA1150 CPU got the VRM ondie? Not to mention FDI link is moved there as well from chipset and other various parts.

Based on the past history we try to keep a socket for around 2 years. The first year is matched up with a new micro-architecture and the second is for the die strink. So think of 2nd generation Intel® Core™ processors (Sandy Bridge) and then the 3rd generation Intel Core processors (Ivy Bridge).

I'd like to add that in my experience, having built my own systems for well over a decade, most of the time you get a motherboard & CPU combo and rarely will upgrade it. By the time it feels long in the tooth, you're better off buying a motherboard with whatever the latest socket and CPU is.

Remember that "end of life" doesn't mean it sucks or is unusable anymore in the computer world. It just means that it's not actively produced. I'm still running a C2Q Q9650 and it runs fine for what I need it to do. And I'm someone that used to upgrade about every 6-8 months. Games still run fine on it, even though I can't get the latest super duper resolutions and graphical eye candy. Granted I'm eying Haswell for a computer upgrade.

Thanks! Looks like there isn't much of an alternative, since he wants his computer redone within the next two weeks and I'm thinking his budget isn't going to permit the launch products for Trinity. Plus, new motherboards, early BIOS problems, and well, its AMD. If he wants to upgrade the CPU in a couple years, there should be plenty of used SB and IV parts on Ebay.

LGA775 doesn't agree with your history

 

[SPBHM]

I think Intel was still shipping some low end 775 CPUs last year,

but things have changed, I think after 1150 is released 1155 will look like an improved 1156 ("dead" but with more options)?

More options?

 

[SPBHM]

More options?

I was trying to say; 1155 will be "dead" (just like 1156), but "improved" (a lot more CPUs and chipsets to choose compared to 1156)

What I wonder is do the CPU Cooler holes stay the same, thus making LGA1155 compatiable coolers compatiable with 1150 without buying a new mounting kit?

They are the same.

LGA775 was when Intel was still producing chips like they were desktop instead of going for more of a fusion chip / soc.

1st Gen Intel Core iX architecture
1366-Integrated Memory Controller instead of FSB
1156-GPU and CPU on the same chip (on dual core models), they were not the same die but still the same chip. Northbridge was also implemented on the same chip

2nd/3rd Gen Intel Core iX architecture
1155-GPU and CPU on the same die

4th Gen Intel Core iX architecture
1150-Integrated VRM on the chip, Integrated Southbridge on ultrabook models

You can't do all these changes without a new socket

Haswell is whole new tech. Lets just hope our current coolers can cool Haswell. From what I heard its whole new tech LGA1155 might need new HSF so brackets fit etc...
DDR-3 will still reign. Buy a 2400Mhz kit with that Haswell. gl

The mounting holes still got 75mm in between. Socket is same size, TDP is lower. So all LGA115x coolers will work.

That's what I am hopping for, sell my Z77 board and CPU next year and upgrade to a HT Haswell Z87 combo that will OC quite well on air with my Phantek 14PE.

Based on what I heard Haswell uses a different transistor than Ivy and will be soldered to the HSF so it should run cooler than Ivy at the same clock.

 

[ShintaiDK]

The only big change with Haswell in the physical area is the move of the VRM to being ondie for desktops.

it's funny how intel just drops couple pins at a time to make you buy a new board 1156->1155->1150 etc.

This is a common misconception. They don't change the sockets to make you buy a new board -- they change sockets because the chips are not compatible. This is one of the results of integrating non-processor functions onto the CPU.

^^ This. Not to mention its impossible to reuse the old socket when you move FDI and VRM onto the CPU.

Whats the difference between AMD FM1 and FM2?

Looks so similar dont they? Must be some evil plot to make you buy a new mobo!

Or else its something similar to this:

Here is also the actual pinlayout if you want to compare LGA1156 with LGA1155:

So lets just drop the socket nonsense for good now.

 

[Charles Kozierok]

It happens even for more benign changes, and has been for years.

Everyone loved when AMD integrated the memory controller onto the CPU die with the K8, but doing that meant every time they wanted to implement new memory capabilities, they needed a new socket. That's one reason why AMD went through so many of them when Intel just kept using 775.
