Coffee Lake 8700k to offer an 11% jump in single core and 51% jump in multithread

[Vali 83]

Here is an example of 8700K overclock (including some BIOS settings), from der8auer (in German but you will get the point).

Why does Intel insist on unnecessarily limiting their CPUs with poor TIM?

My guess would be cost.  If you save $1 per chip, multiplied by one million chips sold, then you have added $1 million to your bottom line.

That was probably a valid business model when they didn't have any competition. With the advent of Ryzen, saving an almost insignificant amount on each processor doesn't add up when compared to the number of possible sales lost (even if it's quite small).

Intel need only do what is necessary to hit their advertised performance numbers for any specific CPU.  Anything above that is on us... which is where delidding and aftermarket cooling come in.  Their strategy is good business... for them and their shareholders.  Which is why they exist.

And .. no more information about turbo mode multi core frequency

i don't see how it's good business to spend 380.00 on the 8700k and then have to take a chance at it no working because of a delid.i would like to buy the 8700k when it comes back in stock, but we shouldn't have to modify an already expensive product to get full performance.

[Vali 83]

I would honestly invest in a better cooling instead of doing a delid, at least on my side. Also in my case, for 7900X, lowering the voltage also helps. Also I still have to keep an eye on the overall power consumption of the system.

A full performance CPU comes always with some drawbacks.

In Germany you can buy delidded CPUs with warranty. So this is what I would do. Why would Ibuy a 7900X for 1000€ and then give away performance due to bad thermal compound? But: Everyone as he wishes :-)

Sure, only delidded and binned as well

I don't think so, I think they are saving heat transfer efficiency as a trick they can pull out of the hat when they need to demonstrate higher clockspeeds but can't get there w/o using soldered IHS.   $1 is a tiny percentage of cost differential compared to the considerable increase in heat transfer afforded w/ solder IHS, or this is what I am led to believe on the topic of delidding.  IOW, Intel is intentionally limiting the performance they can get even as they shrink die size.  I predict at some point you will see them return to soldered IHS in order to meet perf standards.

I wish they would sell an E version of the 8700K w/o integrated graphics and w/ soldered IHS, like my 3930K which still works shockingly good after 5 years of near daily use at 4.42Ghz on air.  Instead they sell this nice racy chip that you can fry a small egg on!

It's actually way harder than many are aware, to solder an IHS to a die. It's quiet a technical challenge and even harder with modern chips.

The following may be an eye opener to some. 

It's not just about Intel trying to make a few more dollars.

Fair enough, and interesting.  That being said my 3930K was soldered by Intel at the factory and we all know by now how precise automated fabrication has become.  What we'd all love to see is simply this:  for all 'K' and 'X' variants, Intel should solder the IHS on and increase the price accordingly charge to cover costs to do this.  I'd gladly pay the freight for factory oem soldered IHS versus this nonsense w/ de-lidding.  For consumer grade CPUs use TIM.  Done!

Yep, fair enough Noel, I'd agree with that. I can see how, with smaller die CPU's, soldering is getting harder and harder and more expensive, but enthusiast CPU's deserve solder.  There are other factors of course, like environmental issues involved with the extraction of certain rare elements required. But yes, pretty much agree.

AMD of course are still soldering, and we can ask why AMD do but Intel don't. The latest AMD CPU's are physically bigger of course, not sure if that's relevant, probably not. 

 

This topic I just started may interest you, re Asus saying Z270 boards could be compatible with Coffee Lake but Intel won't let them...
