How can it be 118, and 156, and 164 though? Especially when 118 seems to be at the highest clock speed.
You are the one that posted the 118 watts. I don't know whick is correct, but they are all too high.

You don't seem to even consider that the numbers are not what they seem, or are simply incorrect.

You seem welded to one train of thought.

Your thinking appears biased to me.

OK, by your own post and others, it seems this CPU takes 92 watts or more, is that not correct ? Thats at full load, and overclocked over 4 ghz.

I don't even know how you connected the 92W with the mystery mobile chip.

I showed Sisoft listing an i3- 8300 at 165 watts, which is obviously not correct, to demonstrate that the power listed by Sisoft can be way off.

Ozzy pointed out that an i3-8300 actually only uses 92 watts for the whole system, not just the CPU.

You then began to say that 92 watts was too high for the 8C16T mystery mobile chip for some reason...?

OK, 92 watts for the whole system. So what does the CPU take ?

I just dropped in this i7 8700 non k to be freaked out with a almost immediate 84cel load with Prime95 with a CM212 heatsink. I applied a few settings to enable a constant 4.3Ghz on all cores.Not sure why the auto voltage was set to 1.39v though lol. Oddly any adjustments to it manually only allow me to drop it to 1.295v. From what i gather i should prob be lower to 1.180v or so?Even putting in like 1.000v still shows it loading to 1.295v under Prime95 and Intelcpuburn.

I wouldn't mind dropping the vcore a bit more but kind of stumped here.Doubt i will lose sleep if its only at 1.295v.I was about to pull the heatsink and see how in the heck i even goofed up the installation till i saw that 1.39v load.That voltage is for like what a 4.9Ghz oc on a i7 8700k right?

Looks like some of the F versions do not use solder. Another reason they should be cheaper.

Recent motherboard firmware updates posted to MSI's website have confirmed support for two Core i5-9400F steppings. According to the recent findings, the P0 stepping denotes an eight-core die with sTIM and has two cores disabled, while the U0 stepping (pictured above) has a smaller six-core die that comes with standard thermal grease. The U0 stepping also comes with a thinner PCB and the same IHS (integrated heat spreader) design found on the eighth-gen chips, as you can see in the image below.

Crazy question, given these "F" CPUs, what's the cheapest overclockable Coffee Lake 6C or 8C? With "fixed" Meltdown / Spectre?

Or is it not a good time to "try out" Intel?

I'm still rocking some Ryzen R5 1600 CPUs, on some X370 boards. Feel like trying something semi-new, in the interim, before 3rd-gen Ryzen CPUs are released. Yeah, probably a pointless waste of money, but what are you gonna do for tech thrills these days...

Or maybe I should buy some Optane drives, and play with caching, or just using them for pagefiles. I saw a kit of GSKill RipJaws V DDR4-3600 32GB kit for $219.99, not to shabby either. Maybe get two of those kits? Would 64GB RAM be overkill for an AM4 rig?

I sold my i3-8100 rig to a member here a few months ago. Although, I don't consider that a "true" CoffeeLake CPU either.

@VirtualLarry I don't know what you consider to be cheap, but 9700k chips seem somewhat interesting.

As far as 64GB of RAM on AM4, good luck. Say hello to DDR4-2133 or something awful like that.

Update 2/6/2019:
Intel confirmed to us that some Core i5-9400F processors do come with pTIM (polymer TIM - a.k.a. thermal grease), but that can vary based on the location of manufacturing.


Sources close to the matter also tell us that the company will transition the Core i5-9400F and Core i5-9400 models to solder TIM (sTIM) entirely in the near future. Naturally, that means there will be no need to differentiate between the two products on the packaging. All "K" series models in the Core i9 and i7 series will continue to come with sTIM, as well. We also learned that the company will use pTIM for all Core i3 "F" series models indefinitely.

Stay away from these F CPUs, you're essentially buying scraps for a premium price.

It won't be a good idea to buy Intel until they solve their capacity problems - it's as simple as that. The only people who should consider Intel CPUs atm are those looking for 9600K and above performance (premium segments, gaming oriented) or those running software that specifically requires Intel hardware. Everybody else should either wait or buy AMD.

Paving the way for their discrete graphics cards?

Is the 9900KFC possibly a reduced cache chip?
