I'm sorry.. are jokes and good cheer not allowed according to you?yea, that was real informative.

What does XFR change the VID to?There are not advertised boost clocks. The top turbo (4GHz for the top model) is guaranteed with 32C of ambient and stock cooler. If you don't have air conditioner, then you are right. But with 25/26C (sane summer air conditioning setting) XFR should kick in even with base cooler...
I never talked about oc. I just said i would rather have pstate control than uncontrolable "infinite boost" a la nv.XFR is better than that type of OC. Is a continuos self calibration of p-states, based on temperature and load. No other OC mean can beat it, at same TDP.
What does XFR change the VID to?
How does it decide this?
Where is the predefined table for Clocks@VID kept?
Is this editable?
Is there a max power cap for XFR?
What's the time skew for max power/temperature after being hit?
Is XFR response based on Hotspots priority first?
What's next on priority?
Plenty of questions...

Elaborate. In the worst case you just end up stuck on what you've had.
Expediting desktop Cannonlake probably isn't feasible, because from what we know so far, Intel's 10nm process is a disaster. It might be more reasonable to expedite Coffee Lake, which (leaks indicate) is basically just Kaby Lake with 6 cores instead of 4. The problem is that Intel is not at all an agile company; something that would take Apple 6 months would take Intel 2 years, or more.
Whether they ship it or not has nothing to do with what they should or shouldn't do. They have major problems with the 10nm process, and even if they ship CL this year, it's already planned to be exclusively very LP mobile chips.
Its a very serious time for him. For a lot of people in this forum actually.I'm sorry.. are jokes and good cheer not allowed according to you?
Enough with the hype. We need real overclocked speeds and benchmarks. I (granted am mostly a gamer, but heavy multi-tasker) have not seen a reason to upgrade my 6 year old 4.7ghz i7-2600k yet, unbelievable and sad but true. Now Ryzen has my interest, but ONLY if single thread IPC = Haswell or better AND stable 24/7 overclock of 4.7ghz or above is also possible on air or closed water loop. If not there is still no reason to upgrade unless your work demands a lot of slower cores.
I also want that. And for free, with the mother board tooEnough with the hype. We need real overclocked speeds and benchmarks.

Well, you can go home because an overclock of 4.7 GHz is probably out of the question.
I think 4.5 is the magic number, I'm pretty hopeful it can hit it
4.5 on an 8 core would be rather fantastic
how high can 6900K hit?
reminds me of fury x fiasco. AMD: oh this cooling is great for overclocking! turned out you couldnt OC shit.I would be surprised if it doesn't do 4.7 at least. I was kinda hoping for 5ghz..

I wonder if people who casually talk about 4.7Ghz overclocks on 8c/16t Zen realize they're gonna have to handle a 200W+ CPU.
I think there are answers to few of them.
1. XFR would probably increase VID to maintain stability.
2. AMD said based on load on per core basis.
3/4. There is no table. Its calculated on the fly.
5. Every silicon has a max voltage. Its probably that as long as temps and vrm are good enough.
6. I think amd said its 100 ms.
7/8. No idea.
To add more questions:
How does the CPU know if the vrm is good enough to supply enough power without burning out the VRMs.
How did they account for scenarios where threads get bounched from core to core.
I wouldn't mind paying $600 for the processor and $600 for a good mobo/ram, but I won't pay Intel $1000+ for a processor. I own multiple Intel, AMD, and Nvidia parts. My point is if Ryzen can't beat a 6 year old Intel processor in IPC OR Ghz, then it is going to be a loser even at $400. Why release something pretending to compete with Intel 8 core chips favorably if they really can't except in one canned benchmark? I WANT to upgrade, but both Intel and AMD have made that a non-reality over the last 6 years of releasing 5% faster chips/year, that is not significant. Can you imagine using a 6 year old graphics card (intel or amd), lol. Maybe I am hopefully optimistic because it is not hard to cool a .9-1v 95W cpu AND AMD says the turbo will be unlimited only depending on cooling. So I can see people with a good air or water cooler designed for a 140W Intel cpu putting Ryzen at 1.1, 1.2, or 1.3v and maybe hitting 4.5Ghz or higher. Guess we will see soon enough.
i belive they are aware of it plus if my theory about XFR is right everyone who will want too use this function fully will have too buy stronger PSU than needed
There is voltage droop protection: if the Vcore is noisy as shit, due to low quality VRMs or PSU, the performance penality is under 1% and the stability is pretty much guaranteed (if there is not too much droop) since there is BTC: boot time calibration. Even if the Vcore were off tolerance, this calibration can offset this problem...
