Hi all I have configured two laptop configurations, could do with some advice,
I do a lot of 4k video editing I use Adobe cc premiere pro, not into games but I need a powerful Laptop to have on site with me for reviews of video etc etc

My question is advice on processor difference

(1) the first system has the 6700k which is pre clocked to 4Ghs

(2) the other system has the 6820Hk, is there software within the system to overclock the 6820HK this to say 4Ghz

my understanding is that the 6820 will use all cores at the 4Ghz if clocked,

where the 6700k does not run all cores if clocked to say 4Ghz and only uses one core, could

one of your tech: guys answer this for me please, i.e am I correct on the above

I want to order my system in the next couple of days so please A.S.A.P.

Thanks in advance for any help

And there's no reason why it should drop down to only one core being in use under load. Indeed 4ghz is the base clock:

Out of interest, what's the thinking behind the 6700k using only one core?

Well I done my homework and there are quiet a few tech specialists whom have said that the 6700K drops 3cores when overclocked

any way I have made my decision I'm going for the 6820HK its no brainer,
it will be a little better for 4k video which chews up processors and graphics cards,

just put 4k on premiere pro timeline and start adding 3,4,5,layers of graphics etc.

I have just purchased a converter called cineform which is excellent and helps anyone whom struggles to edit 4k just my point of view

( Cinec allows you encode and convert cineform videos to prores, cineform to mp4, cineform to h26, cineform to h265, cineform to virtually any professional standard video codec .

Thanks for the reply Oussebon but I am now convinced the 6820HK is the better of the two processors

*headscratch* Your call mate, but it's significantly weaker in pretty much everything at stock, and even if OCed to 4ghz is somewhat weaker.

Not sure if serious. If you're doing extreme overclocking, like pushing it to 7ghz then sometimes the only way to push ludicrous showboat overclocks to the highest degree is to disable all but one core. http://hothardware.com/news/skylake-breaks-7ghz-in-intel-overclocking-world-record
But we're talking Guinness Record Book here, you're not going to be doing anything near that.

People have pushed 6.8ghz on a 6700k with all cores active: http://www.kitguru.net/components/c...th-all-cores-active-on-msi-titanium-platform/
Again that's showboating, so you're not gonna get 6.8 out of the chip. My point is that you can OC quite a lot with all cores active - it'd be a truly rubbish -k CPU if you couldn't. PC Specialist sell desktops with 6700ks OCed to 4.6ghz on all cores active, and that's a respectable and realistic Skylake OC for a desktop.

You can see someone with a Clevo laptop that has a 6700k with 4 cores at 4.4ghz:

None of that to say that the 6820HK is a bad CPU, ofc it's not, but it's simply not true to say it's the more powerful of the two.

I would also have expected a desktop CPU to be superior to a mobile CPU
