    Intels hit a homerun with ulv quads and now with the HQ series cpus. I'm still not convinced on the desktop side.

    AMDs 35W Raven Ridge will not be able to compete with cpu perf with Intel hexcores nor will it be able to beat rumoured 1040 in gpu perf.

    not sure what AMD has in store apart from ravenridge for laptops :/

    A tweaked R1700 to battle Intel HQ series undervolted vega 56 on the gpu side ?

    I don't know about their 7700HQ, but my 7820HK doesn't reach 4k single thread even OC'd to 4Ghz

    Regardless of perf increase (which would probably be negligible in real life) it would take a while to actually get the higher end parts in anything, including Clevo

    On the notebook side they likely intend to rely on the overall single chip package for being reasonable and cheap to produce.

    The benchmark was v3.4.1, single-thread, 32-bit.

    NotebookCheck's average 7700HQ score is 3600. The 6700HQ achieved 3400 on average. This looks like a very typical marginal 5-10% IPC increase that we've come to expect from Intel over the past 5 years.

    Nothing to see here except the extra 2 cores. Useful, definitely, but it was a reactionary measure to AMD Ryzen.

    Extra cores does not tend to impact gaming too much at the moment either.

    +rep for your post:)
    From Hwbot.org
    6820hk@4.2GHz max in Cinebench R11.5 http://hwbot.org/benchmark/cinebenc...Id=processor_4390&cores=4#start=0#interval=20

    6820hk@4.5GHz max in Cinebench R15 http://hwbot.org/benchmark/cinebenc...Id=processor_4390&cores=4#start=0#interval=20

    Havent seen fully working 6820hk passed 4.5GHz in any importent benchmarks.

    You forgot to read the text inside the parenthesis in your Core i7-6700HQ and i7-6820HK Review link "The two Skylake quad-cores could even run as 35-Watt chips under practical maximum load for the CPU, and the specified TDP of 45 Watts should not be a problem for the top model i7-6920HQ. Our K model only consumes more with 54 Watts when we overclock it to 4.0 GHz (3.8 - 3.9 GHz in reality, probably limited by IccMax) – the advantages of the 14 nm manufacturing process are getting smaller in this frequency range."
    Expect the power consumption would be higher if the 6820Hk BGA chips could run stable 4.0GHz in Cinebench R15 and not the confirmed 3.8 - 3.9 GHz !!

    Forget 60w power consumtion with 6820hk@4.5GHz. Voltage will pass 1.4v and the power will be out of control!!:rolleyes:


    Regarding Notebookcheck tested max power consumption for Intel's next best (Skylake) mobile i7-6700hq in Cinebench R15 (31,4w Cpu Package Power)... I tested same clocks with my 6700K@3.1Ghz and the power consumption with equal locked down clocks was a bit over 28W in Cinebench R15. Of course will a cooler chips pull less wattage but still... 28.1 vs. 31.4 is a noticeable difference aka over 11.5%. Say that BGA chips is better binned for low clocks + efficiency is a bit off. Maybe for idle clocks but not for fully load.

    Tested 7820hk in Notebookcheck showing that the hk chips don't run correct with higher overclock(+4.1-4.2GHz). Either due crippled firmware, power settings or thermal throttling. The scores with overclock literally sucks!!
