Processor size

[David P.]

I'm looking at a Z170-K mother board for my next build, and I noticed that it has a "Support 14nm CPU Intel® LGA 1151 Socket" in it. Is this the size of the socket where the cpu goes, if so are there different sizes for different cpu?

No, this is the type of architecture on the CPU silicon at the (basically) atomic level. You just need a skylake LGA 1151 chip for that board.

14 nm is the size of the lithography used to create the chip. 

 

There are not different sizes.

14nm is the process node size. If your CPU was 14nm big then you would need a microscope to see it.

 

The socket is 1151 and you need a 1151 (aka skylake) CPU for it.

I thought a Socket LGA 2011 CPU was physically larger than a Socket LGA 1151 CPU?  And isn't Socket LGA 3647 larger than LGA 2011?

[David P.]

Ok so is skylake just the 6th gen intel processors

He is asking about a 1151 socket, if it would only fit 14nm CPUs, and if there were 1151 CPUs with a size other than 14nm.

Oh okay.  I hope the upcoming 10 nm Cannonlake CPUs will be on LGA1151, and compatible with Z170.  I'm waiting to upgrade the i3-6100 in my laptop (to an i7-K) until then.

It will not. Kaby lake will be compatible with Z170 mobos, but Cannon Lake will (most likely) be a new socket altogether. Makes sense, it'll have newer instruction sets that would most likely not be supported by the current mobos.

Really? .  I thought that there was usually a die shrink on the same socket before changing to a new socket?  And I've heard rumors of 6 or 8 core CPUs on Cannonlake.  I was hoping to put a 6/12 or 8/16 core/thread CPU in my laptop's LGA1151 socket in a couple years, or whenever they'd be likely to be around $250-300 at MicroCenter or Newegg on Black Friday.

Intel broke the Tick-Tock cycle.

Who knows, it may / may not happen. I could definitely see a 6 core CPU coming to mainstream platforms with Cannonlake. But one thing is certain,

They got rid of that cycle.

Upgrade the CPU in your laptop... Despite the fact that that isn't a laptop CPU?

Yes and yes. As @Sors already said, he was talking about something else.

Ahh, so it's 2 generations no matter what, per socket, or something like that.  Personally I think that's way too few.  On a desktop I'd like to be able to keep the motherboard as long as I'd keep a case.  (You have to unplug pretty much everything to replace the motherboard anyway, to me it's not much different than replacing a case.)

For me, it would have been time to have a new motherboard/CPU socket when we transitioned from SDR -> DDR, Serial -> USB 1.0, PCI -> PCI-E, IDE - SATA, or DDR3 -> DDR4, USB 3.0 -> Thunderbolt, SATA 3 -> NVMe, PCI-E -> NVLink, or things like that.  Every year or 2 is too frequent for me.

 

And yes, my laptop - a Clevo P750DM-G, has an LGA1151 socket, and an i3-6100 currently installed.

 

If it was as easy to replace a motherboard (while keeping everything else in place) as it is to replace a video card or an SSD, I'd be fine with replacing them more often.  Otoh, I like to get my money's worth out of them.  I bought a board in 2008 for around $60/70 or so, and it lasted 4 years before it died.  I bought my current desktop's board (ASRock Z97 Extreme6) in 2015 for around $150 or so, and I'm hoping to still be using it around 2022-2023 or so.  (Also I like to keep other parts as long as possible.  I'd update hard drives as I run out of space - my 19-month-old three 4TB drives are low on space already, but as for GPUs, I might still be using a 9800 GT or GTX 275 if I had one, instead of upgrading to a 1060 or 1070.)

 

There's one scenario I can think of replacing it sooner though: selling it, along with the i7-4790K, 212 Evo & 32GB G.Skill Ares DDR3-1600, Windows 10 Pro (7 originally, have disc) to my dad to upgrade his 8-year-old laptop (C2D T7250, 2GB DDR2-667, XP Pro), then building for myself an LGA 2011 system that I can use as a combination gaming/media editing PC and NAS with ECC RAM support.

Not necessarily, but that's the way Intel's been doing it lately.

You tell that to Intel, not me. I'm not in charge of designing the products
