Core i9-7900X Skylake-X Review Shows Up

An Intel Core i9-7900X has appeared for a full review at the site Hexus.net. Spoiler alert, it clocks to 4.7 GHz on all ten cores with relative ease (only taking 1.25 V, apparently, though it racked up nearly 100°C in Cinebench at that voltage).

The review praised Intel's overclocking headroom and general muscle in a mostly positive review. Still, not all is rosy in Intel land. They found performance per watt to not have improved much if at all, criticized the high price tag, and Hexus.net had the following to say about the overall experience:

"X299 motherboards don't appear to be quite ready, there are question marks surrounding the Skylake-X processors due later this year, and at the lower end of the Core X spectrum, Kaby Lake-X is nothing short of puzzling."

It would seem AMD is not the only major chip-maker who can have motherboards ill prepared at launch time, even the mighty Intel may have teething issues yet.

You can read the full review (which is mostly positive, by the way) in the source link below.

Oh, and a special shoutout to our own @the54thvoid for discovering this article.

trparkyMaybe not soldered but perhaps better TIM being used instead of the garbage shit that they're using now. Many of us want quieter systems and that means that the processor has to run at lower temperatures so as to not cause the fans to ramp up really high. There was a story a couple of weeks back where many people were seeing their fans ramp up really fast with their Core i7 7700k chips for no good reason and they didn't even overclock them. I can't help but to think that it's because of the shitty TIM that Intel used. The processor is running hot because the TIM can't draw the heat away fast enough which then causes the fans to ramp up fast.
Totally not what was happening. But interesting take. :P BTW, CPU's don't control fans, the boards they are installed into do. These boards need to be tuned to each fan as an individual, or ramping up speeds is not done properly. This must be done by the end user since board makers have no idea which fans end user may install.

So explain why many Core i7 7700k users were seeing sudden 90c spikes? Again, shitty TIM.

Never seen such thing like that on mine even overclocked, with the current OC the highest spike is 76ºC.

you are aware that better tim wouldnt curb thpse spikes much...right? You also know that temps would spike very close to the same temps with better tim, right?

Stop grasping at straws and give it up already. This is really getting tiresome between you two and your meritless stance and throwing crap up on the wall to support it. Some members are better off learning than sharing bullshit info to form an opinion, a wrong one, and call it The Gospel. Too kany clueless noobs here at tpu... oye.

User error, because they read posts like yours and think they might be right. ROFL.

I don't buy PC hardware, so I think it's all awesome, and enjoy it all, Intel or AMD. I like OC'ing, and both do it, and do it well, and in different ways. The rest, and complaining, man, I got hardware to tweak instead, but it's always fun to take a breath from palying with this hardware and see what people are saying, and have a laugh. I enjoy overcoming the problems presented by hardware, since that's EXACTLY what OC'ing and tweaking is all about.

They used shit TIM? AWESOME! More overhead if you fix it! Why is that a negative?? I'll never know. Enthusiasts can get all enthusiast-like and replace the TIM. Solder? They can't do nothing, game over.

We don't complain about problems, we overcome them! So anyone OC'ing, and complaining about what they run into has an internal struggle they must finish before they can get the results they desire! No fancy TIM or solder can fix that.


I got some X299-ready memory in the mail today. I guess I'll have to fire up the X299 rig and play with and have some fun. Life sucks, don't it? :p

KyuubaIf soldered you would want to OC the chip beyond its limits breaking the designed TDP it was meant for, or you are begging for a burned not only cpu but motherboard.
If soldered the temps would be lower, you would need less voltage for the same oc and you could reach a higher oc at the same voltage. You won't push the cpu past its limits unless you oc professionally maybe.
EarthDoglol again...

If we ignore overclocking, there is ZERO point to talk about the paste...none. it even allows overclocking.
As stated ad nauseam, the paste will last throigg the useful life of the processor. Ypu guys keep thinoong its going to fall apart and outsode of VERY RARE circumstances, production flaws which has little to do with the paste, ir doesnt breakdown

The way you two describe it, people should be shitting their pants their tim is going to go bad, but its quite simply not true. You are using correlation to determine causation which, if people actually understood how things work, isnt the case.

You two are going on and on and on with absolutely zero merit... pure speculation and a lack of understanding...
With better paste or solder stock clocks could be higher and you would be able to oc less. I also stand by my point that overclocks should be ignored except in bencharks so you see what you get stock and what oc-ed. The oc itself is unimportant and comparing overclockability is just silly since the 7900x in this case probably has a lower baseclock than -x threadrippers will have and the boost 3.0 feature apparently doesn't work too well.

I may not know too well how a cpu actually works, but I know intel TIM going grainy isn't good and it has in the past with better TIM and lower temps, so it's definitely a point of concern.

As was said earlier, the difference voltage is nearly non existent from a 10-15c drop. Not sure why you think its even worth mentioning...its certainly not. Now ambient to dry ice or ln2, you have a point. But that is also a 150-250C difference, not 10-20.

So, if solder raises st9ck clocks, why is the 6950x, soldered, have lower clocks than 7900k?????

It gets grainy now??? Wtf???

Nearly everything out of you and your boy trparky mouth has been bunked but here we are days into the same conversation with your same bunked points being brought up...im losing faith in humanity now...

6950x clocks are lower, because it's not one, but two generations old. If you don't even get that, there's no point trying to talk any sense into you.

trparky90c may be within operating parameters but I can't imagine that that's very good for the processor over extended periods of time.
On the contrary those are operation temperatures because they have been tested to be fine at that temp for extended periods of time. Thats what "Operational Temperatures" are.

Yet in the past we enjoyed (relatively) cool running processors with temperatures well below 60c even under load. I swear we're going back to the old days of the Pentium 4 and the "Heat Pump on a Chip".

90c maybe, but 100c? It's definitely not going to help the cpu's lifespan and we still don't know how intel's latest rubbish TIM will hold up. It has gone from paste to some strange crumbly stuff in the past and this stuff may be even worse than what was used on the 7700k (can't really tell since the 7900x isn't that efficient anyway).

well aware of that.. thanks. ;)

There isnt talking sense into me in this case. I make sense, and supported any assertion i needed to. Its trying to teach you two rodeo clowns to listen and comprehend that is the real issue here... and frankly, its goddamn useless. Its a shame really, this is a place to learn, yet, people aren't receptive to it and stuck in their ways...but lord knows you will throw that comment right back at me realizing nothing of which i and many others posts is true. Its a shame, really. Opinions can be wrong. ;)

they were different damn processors and different generations ago... dies were larger and could dissipate more heat to name one, MAJOR difference...

It's not about temperatures, it's the voltage limit since there's no cap(reason to go beyond decent overclocks) on TIM/Solder, if soldered that would allow you as a user to push further, as with liquid metal you are pretty much removing any barrier to do so and that's why you lose warranty because you're technically burning your cpu. Intel won't be telling people ''hey if you delid your cpu you can burn it'' i understand that you can be the guy who knows what you're doing but among the millions you're probably 1 of 10000 who care enought and prevent bad things from happening, the common scenario is this ''You have succesfully oced the cpu to let's say 4.7 ghz at 60ºC then you try a higher value because you find out that there's plenty headroom to go further, you try again 5.0 at 76ºC'' by that you have reached the voltage/TDP limits you wouldn't reach with the crappy TIM because that's the limiting factor Intel have put on the CPU for security reasons, the company cares about their product safety not your enthusiast behavior.

Kyuubathe company cares about their product safety not your enthusiast behavior.
Then why even make an enthusiast product that practically begs to be overclocked? When I look at a processor's box and it says "Unlocked Multiplier" that right there tells me that I can overclock it. If they don't want us doing that then I propose dropping the whole enthusiast lineup altogether.

I have a feeling anyone wanting 5GHz on his SKL-X will run into a thermal wall much before any voltage fries his/her processor.
As mentioned, we had to use Alphacool's Eiszeit Chiller 2000 to achieve usable overclocking results. More conventional thermal solutions just wouldn't cut it. All-in-ones like Corsair's H100i and Enermax's LiqTech 240 hit their limits at stock frequencies under Prime95. The custom loop threw in the towel at 4.6 GHz.

Why can't those liquid coolers keep up with a CPU like the -7900X? Back in the day, a normal all-in-one was good enough to keep the Core i7-5960X running cool, even overclocked to 4.8 GHz. We measured power consumption numbers of up to 250W back then. So, why did we have to force a constant 20°C in the loop to even start experimenting?
SKL-X is definitely much better VFM than BDW-E but that's not much to write about.

Agree with you here, that's a false advertisement from Intel or else the fact that the X or K skus have a higher turbo boost by degault, values compared to non X/K parts.

It's obvious you have a more carefree attitude than someone who would have to pay for their hardware, and would feel a decent hole in their pocket if they'd manage to screw something like their CPU.

What do you mean with "They can't do nothing, game over."? As far as I know you can delid Ryzens to your hearts content. You wouldn't much of an improvement compared to paste, but nobody is stopping you from whacking at it. Or does that go into the "too difficult" spectrum of the enthusiast.

Yeah, free hardware sure is nice, but most of us do not have that privilege/job/whatever you want to call it.

I mention it only to say that I look at the hardware for other things, so that money is the last factor that I consider. It merely "qualifies" my perspective. But yeah, you're right for sure.

More overhead with TIM, yes, but the die is the same aith or without solder, so really boring solder gets you to the end result quicker and with less risks than intel TIM.

Just for a board review. They are all ES, so I guess I'll see if I can't get a de-lid tool and pop the tops and do a write-up about that? I'll perhaps de-lid many CPUs... post some results. We will have to see how my schedule works out with other samples (I still have Z270 boards to review).

After looking at the reviews i think ill stick with my 5960X, I'm not going to spend that much on a CPU then have to delid it and lose its warranty lol, looking at the temps and the overclocking head room there nothing much to be had for a $1500 upgrade.
