i7-6820HQ vs i7-6820HK

how many situations are there where the mobo of a laptop is flexed...? just saying

 

I was thinking to put it in, but here it is - we are talking about microscopic things here, but just like I was kidding, I said the truth as well that's how balls get cracked. Have you ever twisted a wire in order to cut it off, more or less the same thing. Also I know some people do hit their laptops, I've seen a hub/South Bridge that had 10 soldering points (for the balls), ripped-off the MoBo... lovely.

 

umm i can sense no more than a max 4ghz oc on the HK chip.. intel took all cherry silicon for xeons and mobile xeons, we get the rest of the junk stuff =)

 

Send me one and I will find out

They've already shown cinebench @ 4.2

 

the cpu + entire mobo?

whats the voltage on that 4.2ghz quad core? if its around 1.25 then mobile is getting better lol.

 

Cinebench is too short to know if it'll keep the full speeds and high TDP over 2.5 minutes.

Also it was thermal throttling.

 

1.191v

It shows 100W, so I imagine it will be up to Alienware to show the best O/C, since historically, they have the best cooling.

 

Doesn't matter what it showed. I could probably easily get a 4980HQ in a GT72 to draw 200W if I maxed the sliders, tossed 1.3v on the CPU and ran Linpack. Won't matter; it won't hold it for more than 2.5 minutes.

*IF* the 6820HK can hold its TDP for more than 2.5 minutes, then I'll relax my stance on it. Until it has proven that in the majority of high end laptops it ends up in that it can in fact hold 100W+ easily even over a period of 10 minutes or higher, I will assume it acts as all other HQ chips act to this date: 2.5 minutes of +10W over base (for x7xxHQ) or +unlimitedW over base (for x9xxHQ), with the x8xxHQ chips being an unknown performance variant (I know not if they act like x7xxHQ or x9xxHQ), as nobody I've ever met with one has desired to test for me OR has it in a chassis capable of cooling it (gigabyte chassis cannot, despite Aorus and P34/P35/P37 selling with them).

 

ohhh, chances of throttling are like 100%.

 

1.191v at 4.2ghz? no way thats damn good for a mobile cpu. mrfox's good ivy 3940xm was like 1.3v at 4.3 iirc with 2 GPUs though.

but 100w, 3940xm consume less power than haswell and we got it to like 120w with higher than 4.3ghz. i think 4.2 maybe the limit and gets restricted by TDP once again, unless bios is as good as m18xr2.

tbh i'd be happy if it can stay 4.5ghz for over 5 mins

 

Why you gotta bash on the Si? It's a good car.

Here's an overclocked BGA processor:

 

LOL, that's very funny. Considering the curb weight of the SmartCar is about 1800 lbs and the Mustang in this example is about 3800 lbs, it is easy to understand that one can go fast for a very short distance with about 80% less horsepower and almost no torque. Other than having two extra wheels, that's not much different than pitting a nimble little motorcycle against a big brute muscle car. But, at the end of the day it's still a disposable novelty that's only good for a few laughs. It cannot be taken seriously, same as a BGA "performance" notebook cannot be taken seriously if you want something to go the distance. A better comparison would have been trying to use that SmartCar at a tractor pull rather than a 1/4 mile drag race.

 

The Mustang still won.

 

But was that VID or Vcore, if it were VID then Vcore may well be lower due to Vdroop.

 

I'm interested to see what power consumption is like. Just for fun, I had the 4980HQ clocked at 40x4 with a -65mV undervolt and under full load, the TDP was something like 78W, which is absolutely abhorrid and abysmal considering my 3920XM at 4.6GHz x 4 cores with extra flex added produces the same TDP, nevermind the near-instant thermal throttling in the Alienware 17 R2

 

Haswell draws far more power than Ivy/Sandy bridges. Also, what was the voltage? Just because you had an undervolt doesn't mean the voltage wasn't high; we've seen 1.4v stock 4720HQs. For all I know your 3920XM at 4.6GHz was at 1.26v and a 4980HQ with a 65mV undervolt from "default" voltage could have been at 1.32v

 

with exception that the HQ hit a cap and throttles back down, its a real joke.
all eyes on 6820HK CPU. if 40x multi at 1.17v that aint so bad, hope it doesnt have the TDP cap.

 

meh, my 4790K does 4.4 ghz all cores on 1.18V

 

Just for Ref my haswell 4980 runs 4ghz at 1.156 volts so really not so bad. I would assume the 6820hk will be able to do it at less voltage after some of us get a hold of it.

 

The moment i ever get forced into riding the BGA wave i'll buy a BGA rework station next in line.Will it be worth it? Most likely not,maybe while there i should even re add a socket .I think of BGA as an excuse for lazy innovation and engineering,and of course above all else greed.

 

anything under 42x doesn't mean much. as well all know when overclock passes the 4.3-4.4 mark voltage requried for each +1 multiplier increases drastically. can't wait to see if 6820HK will be a real beast or just another clown.

 

All the remarks above were around 4ghz so I was just simply adding information which does not position for a needed reply but thanks anyways.

 

that 4ghz for 1.17v on notebookcheck is pretty amazing tbh, for a notebook but knowing intel, 99% its a picked cherry chip, so most of my hopes are gone anyway. for people who really believe an ES chip could count for any credibility is deadly wrong, any company especially intel is known to give great sample to reviewers.

also notebookcheck in picture showing 4ghz, in their actual article wrote something 3.8-3.9ghz.. like wth?lol

finally my 3940xm ivy is fine at 40x at just 1.23v, when increased to 42x it instantly becomes 1.37v and thats a HUGE jump lol, its not like video or notebookcheck show each individual frequency and voltage to stay stable, they are by far the worst overclock reviewer known. grain of salt in my cup of soup.

 

that 3.8-3.9 ghz is most likely the clocks its running at under stress @prime95 & furmark

Yeah but for GPU benchmarkers and gamers the prime clock makes little difference.

 

i just hate stutter and spikes, which can't be helped especially running ram disk and bunch of other things at the same time. at 4.5ghz my m18xr2 is barely acceptable for my work load lol but fan noise is pretty high.. something like 5ghz skylake would be perfect, but then BGA garbage we lose on silicon lottery.

 

Sounds like the desktop cpu based system is a better option for you.

 

And may I ask why you need 4.5GHz for your workload? Are you compiling a 1 billion lines of code?

Honestly, if you do need it, a desktop Clevo system is what is needed

 

ramdisk with temp files thats always loading needs great cpu speed. especially ffox have like 2000 tabs open and chrome both browser using a ton of ram for cache this lags and stutter. for a lot of people they may not care though but i can't stand it. theres also other software i use ram to cache like video/audio editing which would make my computer at 4.5ghz feel so sluggish, as slow as core 2 duo.

 

yep, aiming for quad channel memory or 6 with skylake xeon on purley platform.

 

Interesting, I thought that was an average/acceptable value? My 4930MX can do 40x4 at 1.1650V.

 

my one is 1.276-1.281 at 4.3

 

hopefully we'll all get one pretty decent. 4.5 at 1.3 would be nice

 

i know there are some 3770k can do 4.5 at 1.1xx

 

those are silicon lottery winners lol. talking about average for laptop 1.28v for 4.3 is decent. if we could do 1.25v for 4.3 that would be amazing.

 

in that case pretty much all ZM owners with a 4790K are silicon lottery winners *lol*

i can do 4.5 ghz at 1.207V load / 1.153V idle, 4.7 Ghz at stock voltage 1.232 idle / 1.285 load and even 4.8 Ghz at 1.286V idle / 1.324V load (although thermally restricted there )

my batman buddies all have pretty similar numbers, actually

 

Nice Post to read, but I still don't know should I buy the laptop with i7-6820HK Overclockable or it's not worthy the extra ($125) to pay for a simple guy like me comparing to laptops to buy according to a strict budget.
Willing to buy Sager NP8678-S (Clevo P670RG) with some customization (SSD, RAM and CPU).

 

best thing is to analyze your everyday usage and check how much cpu powah u need. also, are u into overclocking / tweaking or are u rather the guy who says "never change a running system" and wants everything just to work outta the box? also consider how long youre planning to keep your system and whether or not u would profit from a performance boost via overclocking.

there are just some things that cant be answered by others, ull just have to take a pause and think about your needs and wants we can just provide the info, but not the decision

 

lol, thank you jaybee for your prompt reply, really appreciated. I will try to answer your questions to help decide if to buy the overclocking cpu or just stick to the i7-6700HQ that offered by laptop defaults:

1- are u into overclocking / tweaking? Yes, I can do that but never did it before. Just watched some youtube videos and I think I can handle it.
2- how long you're planning to keep your system? 3 years at max I guess
3- would profit from a performance boost via overclocking? Yes. My plan to profit from it as I enter the 3D word.
But I still in the beginning and want a laptop that can handle the rendering and modeling (not interested in gaming) while, but I can't go for customizing a Desktop instead of a laptop because of the shipping and delivery cost, as I live outside USA and it costs fortune to deliver a desktop so i guess it would be better to add that extra cost to a high end laptop, at least for this purchase order


Thank you btw : )

 

your answers point to the 6820HK then be sure to invest some money into an extended warranty, especially with such a system where a single hardware failure would make a whole mobo exchange necessary! add to that your ordering in the US while being outside it, that extra investment surely brings some peace of mind

absolutely valid point, thank you Jaybee, and I will add it to the cart. Thank you!
So, you go for that the 6820HK is worth overclocking?
As in previews posts ryzeki still didn't decide if overclocking the 6820HK worth it or not, depending on the TDP control results which he waits to see. "I assume".

 

yes, thats something to consider surely. its great that u can overclock it at all, since the HQ models have locked multis. our resident NBR CPU buster @D2 Ultima is checking the new skylake mobile models as we speak, be sure to check this thread of his for updates:

great link ... thank you again : )

 

Sorry to be out of subject, but I have a nother question regarding the Thunderbolt 3, I'm confusing now of which model to consider to buy Clevo P770DM (or) Clevo P670RG?
What I need is to be able to connect and run 2 monitors together for the 3D work.
My question: is the model Clevo P670RG capable of running 2 monitors together or I must have the Thunderbolt 3 built-in in the system like the model Clevo P770DM to be able to do so?
Thank you

 

Ah! you naild it in another post : )...
"I'm a bit confused about Thunderbolt port...Are the two mini display ports on the P650RE/P650RG Thunderbolt ports??
Only PxxxDMx models have TB3 which is part of their USB 3.1 ports."

So, please let me rephrase my question again as I dont want to loose the 980M 8GB card for 970M 6GB card if I changed the model P670RG to P770DM as they all have only the 970M 6GB model. What should I do if I want to run 2 monitors together with the model Clevo P670RG which missing the TB3 ? like an external device or something, is this applicable?

Thank you,

 

LOL NO

then batch of lucky people and cpu all goes towards clevo and its reseller

4.7ghz at 1.285 is pretty good, i have seen 4.8 at 1.26 though. depending on the lottery, there are better prices too. i have seen ivy 4960x on 5.5ghz at 1.38v LOL super legit water + mini ac cooled.

as we all know 99.999% of chips goes up way higher voltage once a certain clock hits and voltage required shoots wayyyy up

 

two external displays shouldnt be a problem on the P6. i dont remember tje exact number of display outputs in terms of HDMI and mini displayport / regular displayport, but iirc u were able to run 2-3 displays simoultaneously so no, ure not bound to the tb3 port for that.

You really helped me much Jaybee, thank you: ) I still actually consider your opinion to help me more to choose which best configuration from your stand point of view between those two models, which I tried customizing them within my budget. but some configurations harden my choice specially the processor. Its very confusing to which item to leave for another, so I hope if you could bare with me more please, and help decide which one the best as if you are buying them for your self, and I will follow you from there : ).

1- The first model: Sager NP9778-S (Clevo P770DM)
- The listed price before customization in XOTIC site is $1,969.00 after modifications $2269.00

* 17.3” FHD 16:9 LED Backlit Wide screen (1920x1080) Super Clear Matte Type Sager IPS Screen (SKU - SSC879)
* 6th Generation Intel® Skylake™ i7-6700K (4.0GHz - 4.2GHz, 8MB Intel® Smart Cache)
* IC Diamond Thermal Compound - CPU + GPU

* 250GB Samsung 850 EVO M.2 SSD - Default
* 1TB 7200RPM [SATA II - 3GB/s] (SKU - HDDX97)
* Standard 230W Sager AC Adapter
Just customized the GPU * GeForce™ GTX 980M (8.0GB) instead of GeForce™ GTX 970M (6.0GB) and that jumps up the price to my max budget already.

2- The 2nd model: Sager NP8678-S (Clevo P670RG)
- Listed Price $1,819.00 - After modifications $2164.00

* 17.3” FHD 16:9 IPS LED-Backlit Display with Matte Finish w/ G-SYNC Technology (1920x1080) (SKU - SSC882)

* 250GB Samsung 850 EVO M.2 SSD Slot 2
* 1TB 7200RPM [SATA II - 3GB/s] (SKU - HDDX97)

- The Budget within $2270 and my concern goes for 3D applications and Rendering settings *Not games, while can't afford the Quadro GPUs now at this purchasing.

I understand from some of your other posts that you prefer the P750DM as a machine, but is it worth despite the differences between RAM & the SSD in P770DM 16GB - 1 SSD 250GB and 24GB RAM - 2 SSD 250GB in P670RG?

I also tried to search and find the differences between i7-6700K vs i7-6820HK after the OC, but couldn't determine which one is better as all I found that they are close together 4.8 vs 4.5 GHz, and don't know if I should look and search at something else to compare between them or just the GHz is matter.

* If you really consider the processor as a huge factor plus* the thunderbolt port worth to go for the P770DM, then I'll go for it.

Thank you

youre right in your assumption that i prefer the ZM/DM series, but that has to do mostly with customization and tinkering factor: i just love to open up my machine and take out/replace/tune all hardware parts, and that at maximum performance to last me the maximum possible time (i went with 4yrs extended warranty, btw)

as for your potential configs, they both look great and will give u a good bang for your buck. what you can consider is the following: go with minimum ram & storage possible and upgrade them urself as aftermarket upgrades, that way u can save quite the amount of money. that, of course, depends on your willingness to upgrade those parts urself. but google a bit and ull find that ram and storage are the easiest to upgrade/exchange

that being covered, i can see that the main points for your decision will depend on your need to tinker with ur machine, the length of time ud like to keep it (the longer, the more towards non-soldered components i would tend) and the amount of ram and storage ull need at a given financial budget. the DM will give u less storage and ram at similar price point compared to the RG (again, that is if u choose not to upgrade yourself). so youll have to weigh in how much memory u need in both regards.

gpu-wise, not much difference. more oc headroom on the DM machine but at stock ull get identical performance.

cpu-wise, lets assume best case scenario: ull be able to clock the 6820HK to 4-4.2ghz on all cores with reasonable temps, then ull basically get the exact same performance of a stock 6700K at same clocks (both being the same chip essentially). worst case: the 6820HK is power-throttled just like its HQ brothers and will thus never be able to keep its max turbo speed at stock let alone overclocked for more than 2.5 minutes, and that will do you not a lot of good in longer rendering sessions so depending on that factor, ud be fine with either cpu (best case) or way better off with the 6700K (worst case).

edit: almost forgot - the tb3 port! at the moment theres not much u can really do with it, unless u decide to get urself an external raid array of several ssds and hook it up to the tb3 port to get those insane bandwidth speeds. in the future it could potentially become interesting for hooking up desktop gpus, but thus far there are no enclosures to be seen anywhere aside from modder forums, so a lot of DIY involved. that could change, but in all honesty, i wouldnt base a buying decision on such future "could-be" mind games. go with what u need now and be happy about what ull get, buyer's remorse is a waste of time
