You mean those overpriced fragile toys?

Hey, my G751 is built pretty well, and you can't ignore something like the AW 17 if you think that they're ALL fragile. Also not too overpriced for $850 on my machine.

We are talking about those popular thin laptops, that thing inst thin... BTW try to convert video on those trendy thin weaklings and watch the CPU throttle after a few minutes, meanwhile my good old dell was able to sustain the 3,0 GHz boost clock for one week running at 100% the whole time. (Backstory, i needed a ton of videos to be converted but i needed my main PC, so the laptop was he only option.)

With 6 cores in a laptop, can't wait for Acer's 2nd gen...

My god, with how hot the I7 8700k's already get with just a slight OC, how are these even going to be possible?

 

Realistically, I'd imagine at the most a base I7 8700 non k but downclocked to 4.5 Ghz max boost would be the most a laptop may be able to manage.

[Dabombinable]

It is quite possible that the clock speed will be possible at around 45W or less. This is what my 4790K's (4.5GHz single, 4.4GHz double, 4.2 triple, 4.1 quad) power consumption is after doing web browsing, Youtube, Minecraft and Space Engineers:

You guys are absolute nutcases if you think those specs are real. 7700HQ can only do all-core at 3.4Ghz on its 4 cores 8 threads, there’s no way that they are increasing both core count and all-core turbo while maintaining TDP. I except single core to be higher than previous gen but all-core turbo to be lower.

All Core can easily be that, Intel just needs to add steps to the turbo table so that the high all core only happens at X workload and if temperatures are at Y. Also, TDP is measured at base clock, not turbo clock.

They're also going to be the best binned dies along the efficiency curve they want, which they'll sell at a premium for all of those 5k USD and higher laptops.

That power consumption is a little bit off to me, my i5 chews up more at 4,5 GHz:

I've manually tweaked the turbo levels. Its 4.5GHz for a single core, 4.4GHz for 2 cores, 4.2GHz for 3 cores and 4.1GHz for all 4 cores. Similar to what is seen in mobile devices (except their base clock is a lot lower).

Edit: I've also got the Asus EPU enabled as well, and it does reduce power consumption+VRM temperature noticeably.

Ah, okay, the max multiplier fooled me . BTW those temps are a little bit on the high side...

WEll yeah, it is the stock cooler (BTW, I was going to add that the voltage of your i5 is also a bit higher 1.321V on 2 cores, 1.405V on the other 2, as opposed to 1.302V across al 4 (its currently maxed out at 1.273V).

 

Here it is again playing SE (low GPU load because I'm not on a planet-rendering a 15KM radius on them is fun):

So it is definitely believable that Intel can make 4-6 core Coffeelake parts run at these power levels at the rumoured clock speeds.

Vcore and Core VID is not the same thing. VID is how much the core wants and Vcore is the actual voltage that the CPU gets...

 

/EDIT

The actual max Vcore set in the BIOS is 1,344...

Core VID (which also means core voltage) still affects temperatures and power consumption though. And the Vcore is stock for my 4790K (up to 1.7V), with that being further divided by the FIVR between all of the CPU's components (hence Haswell and Broadwell's ridiculously low minimum power consumption).

The TDP rating for Intel processors is at the all-core turbo speed (source: I just tested with my 7700hq and pulled 45w~ while 4 cores were running at 3.4ghz).

Nope, its how much it wants, the real voltage is indicated by the Vcore...

My 4790K's cores aren't getting 1.7V through them . They'd need to be under sub zero cooling to not fry.

 

CPU input voltage=Vcore

VID=CPU Core Voltage

CPU input voltage is called VCCIN...

Input Voltage (aka VCCIN, Vrin, Eventual Input Voltage)

The VRIN can be thought of as the entire amount of voltage drawn by the CPU and all of its components. 

Vcore is the actual core voltage. IDK why your program shows Vcore is 1,7....

Cooling in laptops do need to be improved but its not too bad. I have an old alienware that i can clock up to 4Ghz with the i7 ivybridge on all 4 cores with decent thermals but only after servicing it. Alienware themselves can cool a 130W GPU well on the alienware 15 so i see no reason why this cant be done.

 

Kabylake i7-7700hq turbo boost uses 65W, not 45W. The 45W is for the base clocks. If power and temps are good, it will boost, if not it wont, and this is the main problem that many laptop manufacturers, even alienware dont get which is why many laptops come with power bricks not powerful enough or heatsinks not powerful enough.

 

The cooler the CPU is, the less power it uses. This is true for every processor so being able to run a 6 core with turbo boost is entirely possible as you guys seem to forget that coffee lake does get shrinks. The problem i see is the intel HD graphics, my current laptop has the intel HD graphics 630 with 24 shaders and so on GPU resources, i dont see how UHD is gonna be better this way except in clocks. If manufacturers could pair the CPU with HBM that would make for a very nice ultrabook and a boost to IGP performance.

 

If only intel would allocate more TDP for CPUs with IGPs, you'd get a very nice portable processing power house by using both CPU and IGP but with 45W you cant use either at max at the same time.

Well its clearly not the case on Asus boards.

It's up to 56w not 65w and I don't know under what conditions it'll do that because mine at 100% utilisation boosts to 3.4 all-core with 45w draw.

I guess you got a bad chip. Some 7700HQ don't even use above 45W under heavy load. Hell most 7700HQs don't even come close to 65W unless you put it into something CPU heavy like Prime95.

you're forgetting the IGP. TDP limits dont apply to boost as thats used when there is room (good voltage, cooling). I easily exceed 45W when i do a CPU GPU task not to forget that nvidia optimus does use the IGP so it does use a few watts. Running a webGL simulation makes the IGP itself use 10W already not while fully utilised.

 

Theres nothing wrong with the CPU power usage, only that some laptops arent designed to cool more heat easily that the CPU risks overheating before the cooling system catches up. Considering that coffee lake gets a shrink it will definitely use less power and have higher clocks.

I do agree with your point, however most H mobile CPUs are found in gaming laptops. GPU task is usually done by dGPU.
