Saw on Reddit r/hardware: Core i7-9700K (8 cores, 8 threads, 3.6 GHz, 12 MB LLC) in SiSoftware and supporting evidence for Coolaler.


Impressive if these turbo clock speeds are true. 8/8 is
WCCF...you know the deal...

https://wccftech.com/intel-9th-gen-coffee-lake-refresh-cpus-1st-august-launch-rumor/

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


I think this is true. Golem says the new octacore CPU is soldered, they have confirmations from various sources. Only the 8C SKUs will be soldered.

The only nitpick i have here is that Your "settings" are not stock for memory, VCCSA and VCCIO. Memory that fast and 20-30% higher voltages are bound to generate extra load compared to stock 2666 dram.

The problem with this thread lately is the same we had before 8700K came out. There were plenty of people claiming it will be impossible to hit 5Ghz on 8700K, that 7700K is in fact rebadged 6700K and does not overclock better etc. The usual suspects were all here.

Fast forward to this day - plenty of chips hitting 5Ghz and there was clear improvement going from 6700K->7700K->8700K even if people deny it. If silicon is willing, and Intel improves cooling by returning to solder, i am certain 8C will hit 5Ghz no problem. The 212 crowd will suffer of course, but everyone else will be just fine, like always.
The octocore i7 7820x Skylake-X was already hit 4.8-5Ghz last year. One member here tooks his to 5.1Ghz iirc and run it at 4.8Ghz as a daily driver. I'm also optimistic about clocks hitting 5Ghz comfortably with adequate cooling. With the power numbers, we'd have to wait and see.

9900K will be soldered. [Videocardz]

The thermal compound used for current generation processors can be removed in the process called delidding. This technique voids the warranty and requires special tools (or a very steady hand). Yet still, it’s very popular among PC enthusiasts.

Intel has not used solder in this price range since Sandy Bridge. The return to soldering is likely to improve cooling efficiency and increase clock speeds further. The Core i9-9900K allegedly boosts up to 5 GHz.

If Intel really solders these new high core CPUs, then I want a detailed account from the loud defenders of paste TIM in the recent past as to why this is so great. We and you know, who you are.

Well it explains why the 8C16T is i9, and the 8C8T is i7. They are charging an extra $100 for solder basically plus the extra die cost.

Who actually defended TIM? We all know it's a cost cutting measure and that delidding reduces temps by 10-15C on average. Is that enough to improve clockspeeds by one bin? I'm not so sure, but it wont hurt to have lower operating temps.

Apparently delidding + LM is actually still better than soldering though, as the thermal conductivity of LM is higher than solder. At least that is what I've read.

There are people here, some apparently so frozen into supporting everything Intel does, that they belittled everyone faulting Intel for not using solder at least in their premium client line. I'm looking forward to reading the new schizophrenic explanation about the glories of solder. Should provide a huge amount of comedy.

Still have no idea who you're talking about, but it doesn't really matter. My 8700K with the so called toothpaste still overclocks to 5GHz on a basic air cooler, and these upcoming soldered chips should ensure they too hit 5GHz no problem. Everyone is happy, including you, because you find this situation 'comedic'. Who am I to judge?

These forums, at least in regard to individuals positions, should not be taken too seriously, in my opinion. With that said, I do get quite a few laughs from some. Kudos to them.

Soldered 8700K would have meant significantly lower fan speeds for the same temps. How much lower? Using liquid metal instead of TIM dropped noise to about a perceived half while keeping temps similar. Solder would be behind LM, but still a major upgrade in terms of noise at iso temps.

Oh I'm not defending Intel's use of TIM at all - I actually upgraded from a 2500K (solder) to 3700K (TIM) so I know what difference solder makes to temps. Let's just say at the time I didn't know Intel made the switch to TIM and I was scratching my head at why my load temps went up 10C despite the 3770K being on a new process. Despite all that, the 3770K ended up overclocking a bit higher than the 2500K.

WR to the 8700K and fan noise, I doubt a delid could reduce the perceived noise in my case by half as that would make my HSF completely silent. It all depends on the fan curve and how that is set, more aggressive fan profiles would probably benefit a lot more than in my particular case.

Ultimately, my take on TIM vs solder is that obviously it's better to have it soldered, but it's not like TIM destroys the overclocking abilities of a chip. You stand to gain about 100MHz, Max 200MHz from the lower temps (or the ability to use more voltage)

Something, something, minimal gains, something, something, thermal cycling will cause your expensive CPU to die prematurely. They're a multi billion dollar company. They spend billions each year on R&D. They know what they're doing. They made the right choice.

Having been in IT for 40 or so years, and having dealt with countless thousands of CPU's, I have never even once seen one fail because of solder. It is likely more expensive to use solder, and you likely spoil more dies using solder. It's not a reliability issue, it's a money issue papered over with marketing speak.

Actually I think he is serious. And I think it makes sense.

I am 100% serious. It's as serious as my belief that Intel's move from 4 core to 6 core to 8 core at the top of their mainstream desktop lineup within the span of a year and a half (after a decade of quad cores) is a set of completely independent acts. Any appearances of being related to external factors is purely coincidental.

Actually, based on the fact that solder is back without any external factors being in play, we should expect a return to 4 core CPUs as well.

8/8 doesnt make sense to me, I would think in most MT workloads a 6/12 8700K would beat an 8/8 9700K, though if the reported 4.6GHz ACT is true then that would go some way to closing the gap in MT throughput

Did you miss the 8600k?

pretty much decimates the 7700k and its similar scenario, replaces 4 logical cores with 2 real cores.

IN HTT optimal workloads it just about beats a 7700k, in every other multi core workload (Which is almost all workloads) it completely overwhelms it.

People need to look past cinebench, it sadly is a very popular benchmark, but it is also very unrealistic.

Check even userbench.

8/8 without a doubt is better than 6/12. Too many people are obsessed with HTT, and its worrying, the amount of people wasting money on 8700Ks vs 8600Ks as an example.

TBH there will be basically no difference in gaming performance between 6/12, 8/8 and 8/16. Even 6/6 suffers little to no performance degradation in the majority of current games.

8/8 will beat 6/12 hands down in games that can handle the extra cores, virtually no games even benefit from HTT.

In almost all gaming benchmarks 8600Ks match 8700Ks, 95% of steam games cant even handle more than 2 threads, never mind more than 6 or 8 threads. The ones that do have more than 8 threads wont benefit in 99% of cases if its fake/logical cores.

When a 8700k noticeably beats a 8600k it may be due to higher stock speed or higher cache size.
