Yeah that also bugs me, they usually quote the base clock and the 1-core turbo, rather than just the all-core turbo which, if forced to pick just one, is probably the number most people care about.

it fooled me once, now i'm stuck with 3.9ghz all core instead of 4.2

Do we have confirmation it's a real quadcore?  So often the U chips are duals even when they're i5 or even i7s

Confirmed.  Tray price $409.  4C/8T, 1.8 base 4.0 boost.  15W TDP.

wow, those seem like good numbers

thats exactly what they want you to think

I wonder what the dual core turbo is.

Wonder no longer.

 

4.0 single.  4.0 dual.  3.7 quad.

Yeah we do need everything to get the whole story I suppose.

 

While we're on the subject, that's another thing that's always bothered me.  They advertise these 1 and 2 core turbo speeds but you'll rarely if ever actually see it.  Due to the way Windows schedules tasks, even a single thread can end up running a little bit on each core, making it only run as fast as the all-core turbo, even if it would have otherwise been able to stick to one and go faster.  At least that's how it has been for a very long time and still was relatively recently... maybe it's changed now but I doubt it.

Well that should do just fine then

You can't really say that with no link to back it up

even then it wont matter what they advertise right? boost isn't guaranteed, I doubt most of the lower end laptops will be able to sustain those boost speeds anyway.

if they don't it's called thermal throttling, which more and more review places are bothering to test since it's a common problem.  LTT has always been relatively good about it.

Hopefully these new Coffee Lake laptops are out by the holidays. It's time to retire this old dual core Arrandale P6200.

Yes this was confirmed by Intel back in May.

This isn't Coffee Lake, this is Cannon Lake.

I think it's time to do away with a distinction between base clock and the all-core turbo.  Just as they specify the frequency X cores will hit, they need to just indicate the TDP at different whole-chip frequencies.  "base clock" is pointless and arbitrary and I'm tired of it existing... should have died when turbo boost was introduced.

base shouldnt be a thing in mobile but it should be a thing in desktop

the difference on my 7y30 was 0mhz

my i7 never ran at boost when under all core load

only stock

well it won't turbo if there is something wrong, like using too much power, too hot, etc. but in a well functioning system, that shouldn't be an issue.

 

So to address your original comment, seems to me that if anything, it should be the opposite of what you said: a thing on mobile but not on desktops.

not power limited 

voltage was auto

stock bios settings, not even XMP

60c loads in 3.5ghz

I can't imagine why it didn't work, I'm just saying there's valid reasons why it might not turbo.

 

However, in defence of my mission to abolish the concept of a "base clock", should it not always just run as fast - but only as fast (and no faster) - than it can given certain conditions?  Again, base clock is just an arbitrary value.

This generation of mobile CPU's are Cannonlake, not Kaby Lake. I wonder if there will ever be mobile Core i9 CPU's?

base clock should be guaranteed as long as it's within temp limits (why would Intel make a CPU that even on worst one possible and  scenario, throttle on default TDP?)

 

turbo boost all cores should be what most people would get within power and thermals

 

turbo boost single should be a thing or not a thing, sorta fun to know 

[JohnnyCorporalTech]

with quad cores in thin and light laptops, and with Max-Q design, Laptop manufacturers will be able to make some pretty powerful Ultra thin machines. 

 

I cant wait to see an XPS 13 with a quadcore and a Max-Q 1060 or something.
