Intel Core i7-8750H/ i7-8850H/ i9-8950H Coffee Lake

My statements apply only to the Clevo P950 and P955 models only. I don't know much about the GT75, so I can't comment on it.

 

It's not the laptop. It's the design.
You said that on the Clevo, the GPU VRM's are cooled by the CPU radiator, right?

I said that on the MSI, the GPU VRM's are cooled by a radiator that is cooled by the CPU fan, although the CPU has its own radiator that is NOT directly connected to the GPU VRM radiator (note: this changes on the GT75 Titan, there the CPU and GPU both share a 'half' radiator that is separate yet 'attaches' to itself like half of puzzle piece--totally retarded system, but not talking about that).

So on your system, the GPU VRM's are cooled by the CPU radiator. The CPU radiator ALSO has to cool the CPU also, as it has to dissipate the heat from the CPU plate. therefore, the radiator can get easily saturated by the GPU VRM's heating up, causing the CPU temps to rise because the radiator now has to cool two things rather than one.

so @Dennismungai 's point about the CPU heating up when running furmark is entirely logical and valid, so valid that even the great Leonard Nimoy would rise from his grave and give William Shatner a nice punch to his obese gut

On the MSI, the only thing that happens is the CPU fan becomes less efficient since it now has to blow heat from 2 radiators rather than 1. Yet even THIS causes the CPU to heat up when running Furmark--the hotter the GPU gets the hotter the "barely idle" CPU gets, so if such an issue happens on the MSI, it's going to be worse on the Clevo.

That's my point. So I stand by @Dennismungai here.

Plus even if the physics were "wrong", there's still the good law of thermodynamics you have to deal with.
GPU gets hot.
GPU heatsink gets hot.
GPU heatsink gives off heat into the chassis because it's hot.
Ambient air heats up in the chassis because of the hot GPU.
CPU heats up because of ambient air being hotter because the GPU heat plate is hot.

Now if the entire exposed plate were room temperature and ALL of the hot air went DIRECTLY to the fins and none got leaked into the chassis, this wouldn't apply. But have you ever touched a heatsink base with the GPU running at 75C and had the heatsink cool to the touch with only the fan exhaust vents 75C?

 

That heat pipe is not transferring enough heat from the GPU VRMs and MOSFETs to saturate the CPU radiator. If the CPU radiator was saturated, increasing the airflow through through the radiator will remove this extra heat and therefore CPU temperatures should fall. If you set the fans to 100% using Fn + 1, you should see a significant drop in CPU temperatures.

If you were to take a hacksaw to the heatsink assembly and saw off the heat pipe connecting the two heatsinks together, you will see no difference in CPU temperatures when loading both the CPU and GPU. Bear in mind that I'm talking about the Clevo P950 & P955 here and NOT about any MSI laptops.

 

He still don't get it. Some Heat will leak from the whole GPU heatsink into the VRM area (with this Unified HS design) and then being transported to rear Cpu heatsink (Metal conducts heat ). Not only the heat from the VRM's will be pushed to Cpu rear grills. Add in a second engine on same old sized single radiator intended for one engine.... And you should get it.



If people don't call this a Unified heatsink design?

 

Yeah, you nailed it. Good analogy, too. If the Explorer they tried to give me turned out to be one of the hybrid treehugger pieces of crap I would be livid. If the AMC Pacer had an AMX 390 Crane motor in it I would say it was a decent compromise, in spite it's disgusting aesthetic qualities.

The average consumer is the problem. Their ignorance and technical incompetence destroys everything for the rest of us, because these muppets are the focus of all notebook marketing and design objectives. Their abject stupidity makes sales based on marketing lies and distortions as easy as shooting fish in a barrel. They might be easy to harvest, but fish that consume their own waste taste like it, too. Wild salmon are delicious. Hatchery salmon are toxic.

 

Only a small amount of heat will travel from the GPU heatsink to the CPU radiator, certainly not enough to affect CPU temperatures. You have no evidence that this is increasing CPU temperatures. I'll repeat myself again: if you saw that heatsink assembly into two different pieces, you will see NO decrease in CPU temperatures.

This is a unified heatsink WHERE THE CPU AND GPU DIES ARE CONNECTED TOGETHER:

 

Book mark this for your own reference.

When the older separate heatsinks from Eurocom arrive, I'll install them and re-run benchmarks and thrmal stats on the Q6.

That will be the provision of empirical experience.

 

Take a benchmark of your current temps with MX-2 and re-benchmark your temps with the same thermal paste and the same program(s) (not Furmark or Prime95). Please try to ensure that the only variable is the old vs new heatsinks. I really doubt that you'll see much of a difference. Oh and don't try putting liquid metal on your laptop. It will not end well ...

 

Will do. Looking forward.

 

Earlier on in the day (around 11 am local time), I used one of these copper sinks you put on the Raspberry Pi on the Q6's PCH, and with that mod, my PCH temps are now 15 degrees lower on load and idle (~40 on idle, 65 on load. Before: ~60 on idle, high 80s on load).

This is what I used: https://store.nerokas.co.ke/index.php?route=product/product&product_id=150

The copper heat-sinks have a small adhesive pad at the bottom that sticks to the PCH's die. I used Kapton tape around the PCH's silicon (like a sealant, in the same way you use it around a CPU's silicon to prevent LM from leaking) such that no copper would come in contact with anything conductive.
These fins seem to be doing a great job so far.

 

Regarding more vs less shared pipes between Cpu and Gpu. See the differences. For Clevo P750TM1-G. Forget the pict of P775TM/TM1 in the link. Focus on P75x series HS who is for @yrekabakery’s machine.
The statement... “If you want a more unified HS, you could get the P775DM2/DM3 one. Not sure why you would though, as both CPU and GPU are likely to run hotter”

I'd gladly agree with the OP on that summary.

Related, I'm seeing the need for a thermal pad on the highlighted area, which my P751DM2-G machine lacks.

I just ordered for that heat sink too because I'm not taking chances with the longevity of my hardware.



I'll definitely need to address that.

Thanks for this, Papusan.

 

Alienware 15 R4 2018 Gaming Review - i9-8950Hk + GTX 1080 - The Best Gaming Laptop Yeah, its hot


The Unlocked i9-8950Hk running nice 100C and saved by Power Limits and throttling.


Yeah, damn nice Physics score results from an Unlocked 6 core i9.

 

A 1080MQ barely faster than a 1070 and a 6 core barely faster than a 4 Core 6700K

Progress...

 

which one cost more? 1080MQ or 1070 and by how much? i thought for sure a 1070 is faster than 1080MQ because of ngreedia. looks like they dont have full 100% balls to do that yet, but soon... soon we'll have 1080MQ lower than a 1060.

 

Alienware 17 R5 review – ultimate mobile gaming rig (i9-8950Hk - Gtx 1080)laptopmedia.com
Killed by Acer as usual. The trend started early 2015. Edit... For the 4th time in a row


As well killed in 3Dmark Firestrike benchmark by it's predecessor from 2017. It's called progress!

Max CPU load
In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average core temperature (base frequency + X); CPU temp.


The 2.49GHz beauty.

Exactly

• Great performance (up to Core i9 + GTX 1080)

As you can see from the chart above, the cooling system manages to handle temperatures low even after 15 minutes of 100% load. However, just 15 seconds into the test and the clock speed drops below the base clock of the CPU. Nonetheless, an internal temperature of just around 60°C is more than enviable.

We have to note that these low temperatures come at some cost. Apart from the lower clock speed, the fan noise is very high and you could probably blow dry your hair on the rear vents.

 

Ultimate cash grab, courtesy of Azor BGA trash.

Well, if there's a takeaway from this: If you have a good, well cooled laptop from the Skylake/Kabylake era with Pascal - based GPUs, keep it and skip this generation.

 

For the 3rd time in a row. I need to fix it. I will edit my previous post with 4th
http://forum.notebookreview.com/thr...scussion-thread.794965/page-375#post-10474108

 

NO NO NO NO NO, that Firestrike score for a 1080 is way too low.

 

Talking about skip this generation AW and jump on next refresh... If this is the real deal The next generations Alienware’s will come with 40% less weight and 17% thinner chassis.

The correct way engineering much better (very needed) cooling capacity than what you can find in the “thicker” and heavier predecessor.

In short... Dell make ready for coming 8 core Intel Mobile processors.

Edit. And of course... Smaller max battery size (90 wHr vs 99 wHr) + 2 less storage slots.. Less space in the chassis due the massive shrinking means you have sacrifice either the battery or use a smaller MB PCB in the thinner notebook chassis. And YEEE, smaller Motherboard PCB means normally less space for screw attachment to heatsink and less ssd slots. Dell ticked at least both of the boxes

 

I have lost all hope.

I'd hoped never to say this, but Dell's Alienware division is on an irreversible slope.

Form follows function! No workarounds.

BTW, this community has company reps. Do you even take feedback from these forums on quality control?

Here's a recurring theme for the Alienware line: Fix your heatsinks, get rid of the tripod mounting design, and test new units in production thoroughly prior to shipping.

Is that too much to ask for?

 

@Mr. Fox we went from the glorious m18x down to this trash lmao. remember back in the days m18xr2 was an actual upgrade from r1. mobo replacement, 1 piece of chassis along with 1-2 storage cables/bracket and thats it. off we go to enjoy more storage + upgraded CPU and heatsink.

now its 100% buy brand new laptop! for $4000. just thinking the people who bought acer 21x at end of 7th gen CPU lifecycle, they are stuck with a $9000 weight and thinking they got best of the best.

 

Acer Predator Helios 500 Thermal Testing - Undervolting and Overclocking
Jarrod'sTech
Published on Aug 28, 2018
The Acer Predator Helios 500 gaming laptop has some powerful specs, but how hot does it get and is there any throttling that affects performance? I’ve tested the i7-8750H and Nvidia 1070 configuration, although it’s also available with the overclockable i9-8950HK or AMD Ryzen with Vega graphics. We’ll also see how performance changes with GPU overclocking and CPU undervolting with some game benchmarks.

 

i quite like the thick vents, i think better yet they should just go full vents on the back and end of left/right more vents. no ports on the back required, just all vents/fans.

i just know the fact that inside heatsink design/hardware will be a let down tho

 

Let me see how the AMD build performs.

 

Acer is a bit slow to market with announced laptops, they just started delivery into the India market - no online sales... IDK when it's coming to the US.

 

My comment exactly on that video. While generally better than the rest it's another samey mobile 6 core, power and thermal throttled at stock, that turbos higher with an undervolt and ungodly levels of fan noise.

sadly more BGA! also this screen concept has been out forever so even if its 20 or 21 inch its just meh with BGA hardware.

 

One more, but the bigger brother... Alienware 17R5 and it's i9-8950Hk running in full flower. Physics even lower. 15244 this time.

 

well i can't understand the language but its prob nothing worth watching anyway. watch cancer hardware + cancer firmware do its best to throttle, not my type.

 

Watching just gives you more examples and reasons to hate trashbooks. We already have enough reasons, and when you pile on more it merely becomes a basis for discouragement about a tragically hopeless situation with no chance of remediation.

 

Yees, finally.... Alienware's well known second lieutenant Umar walks through the Alienware 17r5’s Alienware Command Center features, Overclocking etc. He got amazing results from the Unlocked i9-8950Hk in the AW17R5 13006 in 3DMark Firestrike Physics score with 6 core's Core i9 is I don't know what to say

 

That is a truly pathetic result. It is even more pathetic that they have no idea that what they are advertising is laughable. The CPU and GPU are both performing poorly in that example. Maybe they live in a bubble. Clearly, they don't have a proper awareness of the degree of their product's inferiority.

Compare that to the EVOC 16LG1080 / Eurocom Tornado F5 with two less CPU cores. Just... really... sad.

https://www.3dmark.com/fs/12693072

 

Umar Khan @AW Khan should know Alienware’s products better than anyone else on this planet. Isn’t he Tecnical Marketing Manager at Alienware? Yeah, He is.

Edit... http://forum.notebookreview.com/thr...or-anything-on-awa.770195/page-9#post-9910935

There is something I don’t understand... Why put overclock profiles 1 equal stock default clock speed for i9-8950Hk. I have seen Aorus have done similar for their gamingbooks. But they have drag it a lot further and put the overclock profile 1 for their High-end laptop below stock clocks.

 

I lost it at the CPU idling temperatures.

71 degrees? The actual f*ck?

 

My eyes bleed from looking at these results.

This is Medusa's head. Turns tears into shards of rock.



12% CPU utilization racks up a temperature of ~71 degrees celcius.



Congrats, Alienware. You've played yourselves.

And @AW Khan, now that you're here, take our feedback. Fix AW's cooling. Get rid of that cancerous tripod mount CPU heat-sink design. This is way out of line.

 

At this rate, Alienware is enroaching upon Keurig's coffee makers.

Can LM even save this machine? If you're idling at ~71...

 

Against which desktop CPU could we compare the 8750H? Somewhere between the 8400 (because clock speed) and 8700 (because HT)?

 

Neither

More like a 8700T. Which is 35W and has a higher base clock... that tells you all you need to know about the quality of the dies that get called 8750H.

 

When he earns much more money why would anyone use Windows Home edition and it confirm he uses a Desktop and AW laptops can't even work correctly. 13k final result means its worse than AGA result w/ 980 Ti on side by side comparison on a 1080 BGA book.

 

Watch a little further and see the 5 seconds of turbo before a throttle back to 3.5ghz. Then, even if the scores are low because a stream encoder was working in the background, or a ton of bloat eating 10-15% CPU at idle... the temps are pathetic - and so are the scores even after adding 15% to them

 

Bro don't mix up things. I don't talk about the graphics score, final score or how the graphics card perform. I talk about the +$600 Intel i9-8950Hk performance. See... 13006 in Physics.


Barely 500 point higher Physics score than the 4 core i7-7820Hk BGA from last gen (50% less cores) show how bad it can be. Even with stock power limits the lackluster results shown above shouldn't be possible to reach/obtain...


And it's pretty scary that one of the OEM manufacturer's own big bosses who test it (and know exactly how to use the overclock tools they themself have created) can't see it.. Most likely one of the main reasons we have run into the sad times for laptop performance landscape today... You can't make it better than <what they want it to be>.

 

I mean the scores are in-line with 7700HQ/GTX 1060M 13 r3 or MSI GS series because 16k is too low for i9 HK and BGA 1080.
I can manage 8.3k(stock) 9k(OC) on FS with physics score of 9000-9500 as in my signature. I suppose AW might release Ryzen 1700X or even TR2 with Liquid cooling and even bigger chassis than m18x.

 

This needs to burn.

 

It needs no added fire. That comes preinstalled from the factory

 

Overclocking the i9-8950HK to the MAX! 4.7 Ghz 1524 Cinebench R15 Multiscore!
GizmoSlipTech
Published on Jul 24, 2018
The i9-8950HK is one of the first proecssors that is able to sustain similar power throughputs as its desktop variant, the 8700K, and is in fact able to sustain much higher performance than the 8700k at stock settings, which is absolutely insane for a laptop processor. Check out my results!

@mason2smart

 

So, when modded using what you tell everyone at every opportunity is the "too risky" liquid metal and overclocked and undervolted so it doesn't thermal throttle, it beats a ... bone stock 8700K

And what happens with a similarly optimised undervolt+overclock+delid+liquid metalled (and cheaper! and not soldered!) 8086K? ~1800 cb r15

Some guy (edit) Liquid nitrogen cooled a 8950HK to a measly 5.1ghz and could only hit 1688cb

Also, if you compare the size and noise (they're all ~60dba at full fans) of all the following, aside from the X9 which is definitely the most impressive of the BGAs in terms of weight and thickness while retaining performance, it's not like any of these other "laptops" are materially more or less portable than the other:
X9
428mm x 314mm x 30mm 3.6kg
Helios 500
428mm x 298mm x 39mm ~4.0kg
AW17
424mm x 332mm x 30mm 4.42kg
P775TM (LGA CPU)
418mm x 295mm x 41mm 4.4kg
GT75
428mm x 314mm x 58mm 4.6kg
G703
425mm x 319mm x 51mm 4.7kg
GT83VR (SLI 18", note i9+1080SLI SKU is MIA)
458mm x 339mm x 69mm 5.5kg
GX800VH (SLI 18", Kabylake model, not updated to Coffeelake-H)
458mm x 338mm x 45mm 5.7kg (plus 4.7kg watercooling dock for full performance)
and
P870TM (SLI 17" with LGA CPU)
428mm x 308mm x 47mm 5.6kg (or spec it with the single 1080 GPU and corresponding heatsink, -0.8kg (ish?)

I don't get the surprise that an 8950HK can get close to the 8700K... they're the same dies cut from the same wafers. The surprise is the large variation in i9 performance, dictated by the model it's soldered into

 

Yes, I don't recommend going to extreme measures to get the best performance, it's not really worth the effort in day to day usage. Tune the software first, and that is usually enough. There should be no need to re-paste to get good performance and cool stable operation.

Undervolting, tuning the fan curve, setting FPS limiter to the display refresh and tuning the OC for reasonable gains without causing thermal throttling is more than enough.

Software tuning is enough for 99% of the people to get a nice stable full performance laptop.

Spoiler

99% of the people buying a gaming laptop don't need to pull apart their laptop, drop their engine and add turbo chargers with custom piping for exhaust.

Sure you can go to the extreme's, but encouraging everyone to chance messing up their laptop getting there, or worse recommending they spend $100's more just to get another 10% performance bump that isn't noticeable in day to day use, isn't good advice.

That is the road I warn people away from taking or being taken.

So you got that right, I don't recommend re-pasting or even worse using Liquid Metal as it's not necessary. And, I don't recommend spending a bunch of extra money getting someone else to do it for you either.

Get a nice discounted retail boxed version of your favorite laptop from a local brick and mortar store, a laptop that is getting good reviews by owners that do undervolt and tune their laptop with software without re-pasting, and read their reported results to decide if you can get the same results yourself.

If you get a lemon, return it right away and try again with another unit.

If you want to go crazy and pay big bucks for 10% more performance IMHO you've got a lot to learn about handling your money wisely.

If DIY laptop munging is your hobby, or that last 1% performance to get on the benchmark charts is your passion, then go for it.

But for a general recommendation right off the bat when first talking to a gamer looking to lower temperatures, I'm not going to send them off first thing to do a re-paste.

If they follow the instructions available everywhere online for undervolting, or from me or someone else here on NBR for software tuning, and do the software tuning available to manage the thermal load and cooling, and return a laptop that still thermal throttles after software tuning for another unit - most people will never need to re-paste.

 

Review of Acer Predator Helios 500 (GTX 1070 - i9-8950HK) laptop-Notebookcheck.com

New awful results from the Unlocked mobile i9-8950Hk! Exactly same Cpu performance behavior from the Unlocked i9 processor as with the fully locked down i7-8750H in this Acer Predator Helios 500 chassis,. Only hotter.

processor
The Intel Core i9-8950HK is the strongest mobile processor in the "Coffee-Lake" generation. It has six x86 cores whose clock is at 2.9 to 4.8 GHz. The TDP is typically 45 watts, but this value can not be met if the Turbo clock is to be achieved. Comparisons with other CPUs are possible with our CPU benchmark list .

Acer gets a lot of performance out of the Core i9-8950HK, but the full multi-core performance of this CPU can not be accessed - even in overclocked mode, when the fan is running permanently. The processor achieves a maximum of 1160 points overclocked in the Cinebench R15 multicore test. The significantly thicker MSI GT75 8RG-090 Titan is about 20% faster with the same CPU when loading multiple cores.

After all, the Acer Predator Helios 500 can keep its CPU performance very constant, with some minor fluctuations, the Helios 500 scored in the Cinebench loop an average of about 1130 points under continuous load. On battery power, however, the CPU performance is significantly reduced.





Conclusion

Acer Predator Helios 500, provided by Acer
Hardly surprising: The Acer Predator Helios 500 is also in the 4K version with Intel Core i9-8950HK a successful gaming package, as it takes over the benefits of the cheaper model for the most part. However, in our view, it is not the better choice than the cheaper i7 model: The Intel Core i9-8950HK can hardly exploit its performance advantages. But it leads to higher temperatures under load and together with the 4K display to a higher consumption.
