Explaining Coffee Lake Turbo Boost Variance & Multi-Core Enhancement
ASRock Z370 Taichi Overview
Papusan likes this. -
From watching all the reviews, it looks like there is a wide range of stable OC, and it might be early days BIOS issues as well, as they are using a wide range of motherboards.
The OC range I've seen is 4.5ghz, 4.9ghz, 5.0ghz, 5.1ghz, and a couple of 5.3ghz - but those reviewers also picked the best CPU from a couple of trays of CPU's, so I think that might be cheating.
Most were at or below 5.0ghz at maximum, and under 5.0ghz stable day to day use.
It sounds like you are seeing typical results is what I am trying to say.Last edited: Oct 6, 2017Talon likes this. -

Intel i7-8700K Review vs. Ryzen: Streaming, Gaming, Delidding
There was another one that could only do 4.5ghz, IDK if it was thermal's or power, or it just wasn't stable - or they hadn't put enough time into finding the right voltage setting.
If you say expect to get 5.0ghz, there may be a lot of disappointed people.
jayztwocents could only get higher performance / OC with the 8700k by switching from air cooling to water cooling, and his Ryzen comparison system was able to perform remaining on air cooling.
jayztwocents started the comparison with both on air, and the 8700k couldn't perform on air-cooling high enough to compete with Ryzen.
Intel i7-8700k... does it suck?
There is a difference between top OC stable on water cooling, and day to day running speed on air. I'd say that's still 4.5ghz on air, which is how a lot of people will run the 8700k.
These are all typical examples of why it's important to watch / read lots of reviews / videos to give you a better overall perspective on what to expect when you buy / build your own system.
Fixating on the top performance reviews where they have binned their CPU from a couple of trays of CPU's, where their golden CPU sample is a dream out of reach from most of us.
Silicon Lottery is great, but it's pretty tough to time a purchase with them to get the top performance CPU bin, they are always out of stock on the top bins.Last edited: Oct 6, 2017 -

4.7ghz on 1 core isn't as good as 4.5ghz on all cores and threads.
Either way, you are talking about 5.0ghz on water, right? Not on air, as it's already been said by all reviewers that if you want that kind of OC you need to move from air to water cooling.
So 4.5ghz on all cores/threads on air sounds right, doesn't it? -
-
You aren't suggesting that everyone will get 5.0ghz on air are you?
What do you think a good all core/thread OC on air will be? -

Is that what you are saying?
That's odd as the air cooling range reported so far is stock, and 4.5ghz all cores/threads, otherwise it gets too hot and you need to move to water cooling, and the limit there is still 4.9ghz for many.Last edited: Oct 6, 2017 -

Laptops are air-cooling only, so maybe 4.5ghz on all cores/threads is doable? Or do you think more like 100mhz-200mhz less, 4.3ghz-4.4ghz on all cores/threads? Or stock only?Papusan likes this. -

IDK that new finned radiator on the right for the CPU seems "tacked on", like those useless glued on copper fins boutique sellers were supplying for extra $, which did nothing.
Unless there is air flowing over it, being drawn in from the front of the laptop, it will just radiate heat into the laptop cavity.
I know @Mr. Fox drills out the intake on the bottom to steal the air that was being pulled over the motherboard to get lower GPU / CPU cooling, but that mod would take away the cooling air movement over that new finned radiator. -

Their cooler is a monster huge Noctua 15, with dual fans, it can run 3 fans for a tad more headroom.
Their CPU was an engineering part (as with many reviewers), so it might be a golden sample, not indicative of retail results, it could be better or worse.

Intel Core i7-8700K CPU Review Roundup: High Praise Across The Internet
https://www.gamespot.com/articles/intel-core-i7-8700k-cpu-review-roundup-high-praise/1100-6453851/
giovannibrescancini - 4 hours ago
"Honestly, I'm wondering if most reviewers are actually looking at their own benchmarks before drawing their conclusions, lol. The greatest gaming CPU? Not at all. It is at most on pair with an i7-7700K in that regard, or in fact a little behind since it loses in most games.
I mean, this doesn't change the fact that Coffee Lake is an obviously meaningful upgrade over its predecessor and that the i7-8700K is arguably a way better all-around performer than the 7700K, since it is like 3 or 4% slower than it in gaming tasks but it's double digits faster when it comes to productivity workloads or even mid-level multitasking (such as gaming + streaming) that the average guy/ girl out there will probably do someday.
Even then, this is not what the reviews are saying, they're saying it is the best processor for gaming and that simply isn't true. As sad as it may sound, the fastest gaming CPU in 2017 (and probably until the 9700K release) is a quad-core re-re-release of the i7-4790K, which was the last CPU to jump a real generational gap in that regard."Papusan likes this. -
Also 4.5Ghz on all cores, noway that can be real. There is something wrong there. I could probably run 4.5Ghz on all cores with like 1.15v or something crazy low.hmscott likes this. -
A lot of people were turned away unable to buy an 8700k, that is except for you and the guy that made the video.
I don't think I've heard of anyone else here on NBR that did buy one...
If the rumors are true the quantities won't be enough until 1Q18.
Only 47 people have the 8700k on their wish list? Seems kinda low...

Thank you for taking the time to share info -
It's interesting that Amazon has the 8700k as the #2 Best Selling CPU, when it's out of stock
The 7700k is #1 with the 7600k #3, a lot of Intel fans gave up on the 8700k already?
What's up with only 18 reviews/ratings, and the average is 2 stars?
ShopBLT.com says they have 11,695 incoming units...it's on pre-order...eta: 10-26-2017
It also means that there are 4,779 ShopBLT.com customers still waiting for their pre-orders to be shipped. I wonder how many of those 4,779 pre-ordered hoping to receive / ship their CPU on October 5th?Last edited: Oct 7, 2017 -

Intel's i7 8700K is out of stock across the UK
When will Intel's i7 8700K be back in stock?
https://www.overclock3d.net/news/cpu_mainboard/intel_s_i7_8700k_is_out_of_stock_across_the_uk/1
"Like every major hardware launch day, consumers all over the world are flocking to their favorite retailers in search for the latest and greatest PC hardware. Today with the release of Coffee Lake things are no different.
Sadly, while stock of most of Intel's lower-end i5 or i3 models are remaining in stock, supply of Intel's i7 8700K and 8600K seems to have dried up here in the UK exceptionally quickly, with the only available stock that we can find in the UK being premium pre-delidded, binned 5.1GHz+ models from Overclockers UK.
Normal stock for Intel's i7 8700K and i5 8600K seems non-existent, with retailers like Scan and Ebuyer listing pre-orders with a fulfillment date of November 1st, which is a long wait given the fact that today is October 5th.
If these pre-order fulfillment dates are true, Intel has under-supplied their high-end Coffee Lake series CPUs by a large margin, so much so that the company probably should have delayed the product until they could ship it in more meaningful quantities.
Thankfully Intel's lower-end products like the i5 8400 and other non-K products are still available, as well as Intel's quad-core i3 8350K, though most of this selection of products are not really suitable for Z-series overclocking-ready motherboard chipsets, given their locked nature.
Hopefully, Intel will be able to resupply retailers faster than what is currently projected, as right now consumers are purchasing Coffee Lake with the expectation of a long wait for shipping, by which time the burning hype surrounding Coffee Lake will have gotten cold. "
Time to brew another batch.
http://www.pcgamer.com/intels-flagship-core-i7-8700k-coffee-lake-processors-is-in-short-supply/
"Intel is usually pretty good about making new processors available in quantities to satisfy demand, but for the time being, that does not seem to be the case with Coffee Lake, at least for some of the higher end SKUs. For example, its flagship Coffee Lake chip, Core i7-8700K, is sold out pretty much across the board."
We are sure there are vendors out there selling limited stock at a price hike, but in our glance around the web, the Core i7-8700K is currently MIA. Newegg does not have an stock available, and neither does the Amazon. Over at B&H Photo, you can preorder the top-end Coffee Lake part, but there is no indication of when it will ship other than it's "coming soon."
You may have better luck at your local Micro Center store, though that will depend on the location. Legit Reviews says it sent one of its writers to the St. Louis Micro Center store only to be told that it doesn't have any Core i7-8700K chips to sell. They did have a Core i5-8600K, which is also hard to find, but only one unit was in stock. The store also had some Core i5-8400 models.
"The prices of the four models that they have for sale are just slightly inflated," Legit Reviews said. Micro Center is known for usually having the lowest processor prices around, when purchased in-store.
For a short while, OverclockersUK had available Core i7-8700K processors that it personally binned based on the ability to reach or exceed 5GHz. It was selling chips that could hit 5GHz for £500, 5.1GHz for £600, and 5.2GHz for £800. Those are all now sold out. The non-binned SKU is listed at £360 and is available to preorder.
The Core i7-8700K is a smoking fast 6-core/12-thread processor that is superb for gaming, among other tasks. It will undoubtedly be a popular option, once it becomes widely available. We suspect that will happen soon, but for now, it is a waiting game."
Intel Coffee Lake Stock Situation Looks Very Poor
http://www.legitreviews.com/intel-coffee-lake-stock-situation-looks-poor_198546
"Intel might have launched their Ryzen CPU killer today, but good luck finding the processor you want at your favorite retailer. If you get lucky and find a model in stock you will likely feel sucker punched when you see the price. It appears there is a shortage of parts and they went out of stock pretty much immediately."
One of our writers went to the St. Louis Microcenter store this morning when they opened and they discovered that they didn’t have any Intel Core i7-8700K processors to sell today. They had one Intel Core i5-8600K and some Intel Core i5-8400 models and that was it. The prices of the four models that they have for sale are just slightly inflated.
Intel Core i7-8700K 6-core = $499.99 retail price ( $359 tray price)
Intel Core i7-8700 6-core = $429.99 retail price ( $303 tray price)
Intel Core i5-8600K 6-core = $349.99 retail price ( $257 tray price)
Intel Core i5-8400 6-core = $249.99 retail price ( $182 tray price)
Microcenter is asking $499.99 for the Intel Core i7-8700K and for as impressive of a chip that it is, we wouldn’t advise paying a $140 premium to get it. The Intel Core i5-8400 feels like a good value for a 6-core processor at $182, but not so much at $250.
ShopBLT shows that nearly 4,800 Intel Core i7-8700K processors have been pre-ordered and the ETA for incoming units is 10/26/2017. They have 11,695 processors coming on that date, but that is 3 weeks away from today! Who wants to wait 3 weeks! The good news is that Bottom Line Telecommunications is only asking $387.27 for the Core i7-8700K, which is way better than the $499.99 that Microcenter is asking.
Amazon usually always stock of Intel processors on launch day, but the 8700K product page has nothing available for purchase and doesn't show when they’ll come back in stock.
That hasn’t stopped Amazon from listing it as the #1 best seller though! Some sites are reporting that they only had 15 available for purchase this morning.
If true that shows how low the levels of stock are. Many are happy to get a Coffee Lake processor, but are now left wondering if Intel moved up the launch to just put pressure on AMD. Coffee Lake retail boxed processors certainly aren’t plentiful, so if you can find one at a decent price you might want to snag it!"
http://www.guru3d.com/news-story/in...ill-be-hard-to-get-availability-dramatic.html
"Intel yesterday released their Coffee Lake generation processors. The Z370 motherboards are available alright, the processors however now. We did some rounds here in the Netherlands and availability is dramatic. Intel supplied a dozen or two of the high-end specced processors to distributors, and that's it. "
Meanwhile checking some price engines, the stock availability in Europe has run dry. In the USA the 8700k is also out of stock, I did notice the 8600k on Newegg though.
In the UK some shops are hugely milking the procs they can actually sell. One of the bigger etailer for example decided to test and bin the procs they had, and have pre-binned 5Ghz versions for £500, 5.1Ghz for £600 or 5.2Ghz for £800 in-stock.
A normal 8700k should cost £360, but, that one of course is not available and on pre-order only. Considering most if not all stock 8700K procs will already do 5.1 GHz that's really taking an advantage of your customers - guys, £800 is like 899 euros / 1050 USD (!).
As to why the availability is this low, nobody really knows and certainly not something we have seen or is expected often from Intel. Production is the same 14nm fab node one as Kaby Lake uses. Intel certainly will not shed any light on this. We have however heard rumors that there is lots of Kaby lake stock (processors and chipsets) left, perhaps they will be waiting to clear that stock first before making Coffee Lake available in good volume, that however remains speculation of course.
It once again feels like rushed launch, a paper launch mostly with incredibly low stock available.Last edited: Oct 7, 2017Dr. AMK likes this. -
Looking at feedback and user posts, it seems that there is something that really causes issues with the 8700K series. Even on sites like amazon etc. the CPU only gets like 2-3 stars. I find it really strange that there seem to be issues regarding the CPU, normally CPU disasters happen for AMD. I really hope that those low performing chips are caused by mainboards which will need a new firmware and not an actual hardware problem with the CPU, because this would be the biggest disaster for intel yet if that's the case.
Some chips perform around 1550 points in cinebench and others only 1200, that's a huge performance difference. -

Obviously Paul and Kyle have something messed up with their results and tests and their BIOS options selected. It's unfair to not even select the multi core enhancement in the BIOS as I guarantee ALL 8700K can do 4.7Ghz on all cores locked at stock voltage, probably well undervolted from stock as well.Papusan likes this. -
Here is 1605 cb for good measure at 4.9Ghz on all 6 cores. I dialed up 1.325v with the Asus software on the desktop and ran it. I'm pretty happy with those temps with PK-3 grease and NOT delidded. Imagine my results if I delidd this beast.

Dude one of those guys you listed got into PC hardware just a few years ago. Please do not lecture me about how they are known reviewers and tech experts. I've been building PCs for over 18 years, and was tinkering with them for a few years before that. I got my first IBM with a Pentium 133mhz when I was like 7 years old. Yes I know some guys have been doing it much longer, but I think it's fair to say that a guy that just go into PC building and hardware a few years ago may have easily missed something.
Edit:
I'm not saying 100% there isn't some issue, I don't have any reason to believe that nor have I seen anything talking about that. I'm sure we'd hear about that. My issue was that you seemed to think I was lying about my score for some reason. They're not that unrealistic considering it's overclocked and its close to what JayZ2cents got. I trust him because the guy has been a tech enthusiast for quite some time. -

I think I need to tweak the power limits or current to get it to use the voltage I'm telling it to because the voltage was around 1.34 during the test instead of the 1.41 I'm demanding. This is probably causing it to be power starved. It should also be noted that I crashed once at 1.4v during the test. Regardless I cannot get it to use the full voltage I'm telling it to.

I was merely stating that some users and reviewers have issues with the CPU, which might be a blunder from intels side or the mainboard manufactors side and if the issues is indeed caused by some kind of faulty production from intels side, then it would be a disaster, which I hope you would agree. So next time, read my posts before being angry and post silly things that have absolutely nothing to do with the topic at hand.
