It seems that the current 14nm++ generations are the plan b. Intel has been planning 10nm and the architecture for 10nm for 3 years now. But there are many hurdles to take.

Lots of new Xeon E chips launched.

[Bouowmx]

Spoiler: AnandTech Xeon E summary

PL1 (Turbo Boost long duration power limit) and PL2 (short duration): those terms make a lot more sense than advertising "TDP".

They appear to be real thanks to a reddit user by the name of eric98k providing the tools to do so

Here are my results in screenshots:

Nice find, @dooon

edit:

eric98k also tested the Z370 Asrock Pro 4 and found similar results

He also mentions in his reddit comment that these options existed from the first Z370 bios'

Another evidence, MSI released a beta bios for their Z370 with support for new generation CPU. There is one uncertainty, the bios update could refer to 9th gen with 4 and 6 core SKUs but I don't think this is the case.

Intel Rumored To Introduce 9th Generation Coffee Lake Refresh CPUs on 1st August – Core i9-9900K 8 Core, 6 Core Soldered IHS Chips With Up To 5.5 GHz Clocks

 

[PeterScott]

Liquid Metal actually does a better job than solder for heat transfer and even liquid metal delidded, highly binned 8086Ks were NOT hitting 5.5GHz.

IMO, the i7-9700k will be identical in every way to the i7-8700K. Including the TIM. They already have the production lines going full tilt on these, so all they have to do, is change the microcode ID, and markings on top.

If intel were to solder anything it would be the 8 core part, which is going to produce even higher heat, and also pull in higher revenues, to better compensate the increased production cost of soldering.

 

[LTC8K6]

Also IIRC, soldering an Intel chip did give lower temps, but not much more clock speed.

Soldering doesn't improve max clocks, since that can be tested by pushing the chip limit under light/medium loads (say max boot capable clocks, lighter benches etc), but it does improve stability in that highly volatile state of near max clocks & heavy loads.

A way to rephrase the statement above would be: people who advertise those high 5Ghz overclocks on TIM may finally get a truly stable system too

I meant that solder is not going to give us 5.5ghz stock clocks.

I wasn't contradicting you, merely extending on the idea

But if we miraculously get a 5.5ghz stock clock, I'll take it, even single core.

The idiots, no 8/8 cpu?

 

[maddie]

The idiots, no 8/8 cpu?

Wouldn't that = a 6/12?

 

[PeterScott]

Wouldn't that = a 6/12?

Close, but I'd give the edge to the 8C8T over 6C12T.

But Intel is going to have a crazy amount of SKUs, it really doesn't need to create more artificial segmentation by disabling HT on the 8 Core.

 

[LTC8K6]

The idiots, no 8/8 cpu?

How do you know there's no 8/8 chip?

 

[Dayman1225]

How do you know there's no 8/8 chip?

I assume because of this?

 

[JoeRambo]

5.5Ghz might have nothing to do with solder, but more with 14nm+++ with whatever amount of pluses they are on by now. Maybe they have built a new revision of 6C CFL chip that can clock higher that last years CFL.

And solder? Bring it on please, my body is ready.

 

[Batboy88]

Hey
Coffee Lake is awesome I can about imagine...but I got caught in a bad time wanting to put something a little modern together. So I had picked up a few Z270 mobos and Chips.
On the Supermicro now and 7700k at 4.9ghz and the 3200mhz Hynix kit.

Wish would of waited Longer...look now X299..7820x is a rad deal for that...and you wouldn't even have to have a too fascinating mobo or anything.

 

[StinkyPinky]

It says it is still 14nm++ so unless Intel are somehow breaking the laws of thermodynamics, I don't see how they can suddenly get 5.5GHz even with a soldered cpu.

The 8086K does generally get slightly better overclocks than a 8700K but that could be more a binning thing than a process improvement.

But 5.5GHz? I'll believe it when I see it, even if it's on 14nm+++ or whatever

 

[PingSpike]

Is there anything conclusive that there's actually going to be a 8 core coming soon? All I've seen is an empty space in some charts that it would be nice if there was an 8 core and like 6 months ago a motherboard box from China that said "supports 8 cores" on the front. This talk about 5.5ghz and soldering makes me think we're just going to get an overclocked out of the box 6 core in that empty space on the charts.

The 906EC cpuid code appearing here and there seems to be the best evidence.

I don't think there is a CPU launch on 1st August. CFL-S refresh is coming in Q4 and even if it would come this quarter a launch along with Gamescom or IFA would make much more sense for Intel. The other stuff is unreliable as well, i mean the 6 core is most likely just a renamed 8700k and nothing more, no chance this is soldered.

I don't know...It was Ignorant and again whole new board/chipset....it's Literally about the same Dang thing with 2 more cores....

Yeah, as I said, it's WCCF...
