    Re: AMD Ryzen CPU pushed beyond 5.2GHz on all 8 cores (video)

    LN2 and 1.875V to get to 5.2GHz?

    Hmm... having a quick look at HWBot the record frequency for the (also 8C/16T) 6900k is actually 5.22GHz, so they're there or thereabouts for the higher core counts ... just wonder how that'll translate to overclocks for the lower core counts if they're based on the same die....

    Re: AMD Ryzen CPU pushed beyond 5.2GHz on all 8 cores (video)

    Impressive! my 8350 and 1070 are doing what I need my PC to do right now, but I really am getting more and more tempted to upgrade early just to show some support for these chips, especially given the price, maybe I will wait for a nice motherboard cpu and ram bundle to go online somewhere (considering I will need it all anyway) and use that as an excuse to wait a bit longer haha.

    Seems pretty good. Hope there is some good mileage to be had in overclocking on water and with the Bus Speed as most of the recent CPUs (from Intel anyway) pretty much limited you to multiplier overclocks with only minimal increases to bus speed possible

    That is the golden question, and possibly why the lower core counts are coming out later so the process is a little more mature (and inventory of binned parts increases).

    What's interesting to me is how AMD release at closer to max limits in terms of frequency - Intel might just be playing safer, but it could well be AMD are getting a little more out of the chips with the frequency/power tuning magic.

    If this is the same 14nm process that Polaris is fabbed on, that may have a bearing too:


    from: https://forums.anandtech.com/threads...#post-38366723

    If the voltage curve for Zen is even vaguely similar that would explain them being able to release close to the ragged edge - a long flat voltage plateau, then a steep upcurve. I can even substitute known Zen base clocks on that graph - if the R7 1700's 3GHz base clock equates to the 900MHz Polaris clock at the end of the voltage plateau, the R1800X's 3.6GHz base clock would equate to roughly 1100MHz, requiring around 20% more voltage. Rather pleasingly, since power is proportional to the square of voltage, that would mean the R7 1800X should require around 45% more power than the 1700, and it's TDP is around 45% higher

    That's all a little bit too clean for my liking, but I think it probably points in the right direction. That may well mean that 5GHz is about as far as you're likely to get any Zen processor, although it may be that the thermal inertia of a large chip with only half the cores active will mean it's acheivable with air or water on a 4C chip, rather than LN2...

    Re: AMD Ryzen CPU pushed beyond 5.2GHz on all 8 cores (video)

    Ryzen is also an SOC design which for me hints at a CPU design orientated more towards lower power consumption anyway. So overclocking a chip with so much functionality on-board might not be straightforward too.

    Edit!!

    TBH,AMD is still hitting similar clockspeeds to the FX8150 at launch using a much higher IPC core,but on a first generation Finfet bulk process using HDL.

    Intel is on a third generation Finfet process,so I think most of us expect Intel to do better in that regard.

    But seriously as long as the 4C and 6C top SKUs hit around 4GHZ boost clockspeeds,does it really matter??

    Almost everybody I know does not really overclock their CPUs,so as long as AMD can competitive stock performance,the benchmarkers will always go Intel even if it is 2% faster,ie, look at the Core2 Quad and Phenom II X4 days for example.

    Re: AMD Ryzen CPU pushed beyond 5.2GHz on all 8 cores (video)

    I do wonder the actual reason for XFR is so AMD can maintain higher clockspeeds whilst breeching TDP. So they can advertise these as 65W TDP and 95W TDP chips,but most people will enable XFR,and these chips won't be at 65W or 95W anymore!

    I'm pretty sure that's *exactly* what it's for

    Hmm, I've just had a really obvious thought that I can't believe didn't occur to me before.

    Everyone's talking about XFR and its ability to boost above the top boost clock figure as being the important factor. But presumably there are multiple boost states, like with all modern chips with boost, depending on how many cores are loaded. And if XFR works in those states, you could be getting significant boosts to multithreaded performance with XFR, rather than to single threaded performance...

    Remember that french magazine with the easter egg claim of 5GHz?

    Chips are a capacitive load, so power is proportional to FV^2 - 20% more voltage and 20% higher frequency translates to 73% more power consumption. For a 20% boost to F and a 45% boost to TDP, you'd expect a 9.5% boost to voltage

    can it run 24/7 no ............. so it's pointless
    It's like sayin buy a mini and spend £1m and you have something that a beats a buggati top end...... simply pointless.

    Air and water cooling only matters
