Alright the power consumption isn't great, neither the temps but you an certainly tame them without too much trouble.

Actually, taming the temps may not be possible at all.

If you have a read of this: https://forums.anandtech.com/thread...-20°c-at-4-7ghz.2261855/page-23#post-34053183

you will see that the high temps are down to the distance between the cpu die and the IHS. In other words, the only way to tame the temps is to de-lid and then mount your cooling solution directly onto the die. That is a very old article now, but Intel are still using the same process.

Point taken all I know is if im spending that much money because I want the best, then delidding would not put me off personally. If your buying it purely for multi threaded then perhaps threadripper will be a better choice regardless. We will have to wait to see what it offers.

I think the 7820k looks a pretty good choice tbh. If you spent £500 on a 1800X then and extra £100 is not bad for the extra performance especially in single threaded. Alright the power consumption isn't great, neither the temps but you an certainly tame them without too much trouble. Obviously boards will cost quite a bit too but hey ho if your looking at that segment you should expect that.

Not sure about the other chips though. KL-x is just laughable and the 7900x and upwards should be made redundant to most by threadripper.

The only way it's fair to compare it to the R7 1800X though is in terms of out-of-the-box performance. If you're going to overclock, which basically also requires a delid, you need to add that cost to the price and compare to the R7 1700 instead. Motherboards will almost certainly be more expensive too so all in all, it's a tough sell to anyone but very high end gamers.

We basically don't know enough at this stage about various factors, including motherboard costs and ability to tame temperatures with a delid.

De-lidding dosn't bother me either. Thing is though, with modern cpu sockets if you do de-lid and mount straight onto the core/die your cooling solution would have to have been made so as it can sit inside the metal clamping mechanism. Because of course the core/die is below that mechanism. Years ago when all core were bare, this wasn't an issue.................it is now because none of the cooling company's make such a solution.

Except it's not an extra 100 due to the boards and quad chanel memory. That plus the fact if you buy a 1700x you have a reasonable chance of attaining the same clocks as the 1800x unlike the 1700 where it's less likely.

Wow. This came out super fast! Need to go over the reviews: What's the TLDR?

I'm not trying to compare it to the 1800x as such, one is mainstream the other is hedt. I'm just saying on a pure cost basis of the two cpu's. Threadripper will be much closer to it especially with the quad channel ram

I thought that der8auer was bring out a tool for the job presumably to refit the lid back on. Do we actually know that the die has to be bare or are we assuming?

I think you may be missing the point Doobedoo. If you read the posts i linked to above, the conclusion was that de-lidding just to put "better" Tim on is a complete waste of time because it makes little to no difference in temps. The reason it makes no difference is because of the gap between the core and the IHS.

As i have been clocking and benching since the 1990's i know from experience the difference that mounting direct onto the core makes. LN2 with a specially made pot to sit inside the cpu mounting mechansm works and so does a machined evap on a phase unit as well. Any off the shelf cooling solution would work if the mounting surface was machined to fit inside the cpu mounting mechanism, but of course they don't exist yet.

If you de-lid and then just mount you cooling solution as normal, the gap between it and the cpu will be the IHS you have removed and the thickness of Intels Tim. Which of course gives you no cooling at all.

Direct die cooling with intel cpu's has always been dreadful in my experience ,I've seen it tried with haswel and devils canyon and in every case the results are worse than with Liquid pro/ultra and the heat spreader. I tried it with my 4790k paired with an ekwb evo and direct mount kit, temps whilst lower than before the delid were a good 10 degrees higher than with the delid and heat spreader.

they are in a bit of a poor position as they would like 6 months between x299 and coffee lake to stop people going for the cheaper AND IFFFF they do a 8c16t coffee lake will lose some possible proffesionals as it would have to undercut the x299 platform on price while still being a jump in performance which would probably push it past the x299 8/16, depends how far intel want to push coffee lake and how much they value x299 sales all the while trying not to lose market share to amd.

Well the rumours have for a long time been that Coffeelake will bring hex cores to the mainstream platform. The bad news might be that they come without hyperthreading. Honestly if that were the case the hex core would be utterly pointless. If intel want to regain their dominance they can't keep crippling their own products like this.

TTL seems to know something about Coffeelake. It was made out to be bad news the way he said it

Coffeelake is certainly not bad news and I really doubt Tom tried that yet.

If true (no HT), Intel may as well have slit their own wrists... (and infuriate me beyond anything you'd want to know).

Truly no offense mate: have you then? And, that's what I'd expect a reseller to say of course.

Direct die worked well for me on these cpu's. Gained 75-100mhz when done well and dropped Temps nicely.

It's always worked for me as well Ian.....................all the way from Athlons up to and including Gulftown. The only issue was the amount of Opteron 170's i killed in the learning curve

This again. So drab. Is this thread not about discussing the reviews. You did this exact same thing in every other thread. Buy your Thread Ripper and stop this nonsense.

Exactly the issue extreme care not to kill the Cpu needs to be exercised.

We delided around 50 cpu in one week at Asus hq from Kabylake X to skylake X all fine. Drops Temps 20c+ with conductonaut liquid metal.

He made it out that way. Anyways I hope coffeelake is good news as well? Give us some info Intel?

You are right. I'm talking nonsense. I should get a 7900x and delid it before putting it under an extravagant water loop just to keep intel happy.
The fact that people are defending this is hilarious.

I am talking about the reviews and the conclusions are it's hot , hard to cool and not much faster and infact sometimes slower than the x series they are meant to replace.
