What is your suspicion?Wording is ambiguous. In fact "enable higher clock speeds" is actually... reaffirming my suspicion.
Damn, i need to have a meal and relax, that starts to worry me.

1. Assuming AMD will be outsourcing manufacturing of some Ryzen to Samsung, can they differentiate dies from different and supposedly a bit better process with letter X?
Fair enough... but the same argument works for K CPUs.I wouldn't say that XFR carries any premium. It's the higher clocks that do, same as with Intel.
As the saying goes, it's all too good to be true, plus there are hints that AMD's marketing as usually fed the overhype machine.Some ppl here seem to be on a mission.
3930k has extended frequency range when compared to 3820.What is your suspicion?
If I'm getting you right, that would be my worst case scenario for what XFR is lol3930k has extended frequency range when compared to 3820.
Yep, but since i do not have access to IEEE article (did not bother with it yet), i have to ask. Is the part where conclusion made on turning these power savings into increased frequency... speculation or mentioned in the article itself? Because if it is the former then entire article describes power saving tech in Carrizo/Bristol/Mullins and then proceeds to make a jump inverting their purpose to increase frequency. Make no mistake, it is certainly possible to do. But the wording of the slide and Lisa's words definitely do not state outright that clock *increases*. Just that it can be increased.
Because XFR carries a hefty premium tag with it. Got to figure out why.
Inb4 AMD next leveled everyone and put a premium tag on barely useful feature.
I am the glass 90% empty type of guy.If I'm getting you right, that would be my worst case scenario for what XFR is lol
Thanks, i can see how that may be used, should it all be improved further, to enable some sort of larger and invisible at glance turbo clocks.Quoting the paper numbers:
3930k has extended frequency range when compared to 3820.
The official slide deck makes it clear that XFR means more than just an unlocked multiplier
No, it does not quite tell us of automatic, real-time overclocking. Second part is non-sequitur because we already have that in form of manual OCs. The third part could suggest that it does oc automatically, or that the allowed multiplier is scaling automatically... that still can be interpreted in bad way, as you see.Dictionary said:Permit -- to consent to expressly or formally/to give leave/to make possible/to give an opportunity
Of course, but the best way about it are vague statements. And well, statements are indeed vague except the third part.But they generally do not lie outright about what features are or will be included.
Non XFR CPUs will boost up to maximum turbo boost described. For example R7 1700 will boost up to 3.7GHz and not a single MHz more, in 25MHz increments as described in the precision boost slide
If I'm interpreting the XFR slide right, well, its "extended frequency range". This applies to turbo. XFR enabled CPUs can and will boost further than the maximum turbo boost clock for these parts, the Ryzen die has an insane amount of monitoring going on plus who knows what else more sorcery that AMD has developed all these years of being limited to 28nm processes to make their APUs power efficient, I don't see how all of this can't be used the opposite way, to keep boosting up.
How does Ryzen boost work? Is it single core boost? Is it all core boost? Is there tiered boost as in single core, dual core, quad core boost? How much will XFR let boost go above advertised boost clocks? How far does XFR go with stock cooling, high end aircooling, custom loops and LN2?
Wait for reviews, February 28th is only 9 days away.
If it's another of AMD's fine marketing blunders like Fiji being an overclocker's dream, then you can save the extra money that AMD is asking for the XFR parts, and overclock manually to your heart's content as all Ryzen CPUs are multiplier unlocked. R7 1700 is $320, R7 1700x is $390. If clockspeed and XFR are the only features that differ, and XFR is a gimmick, then those extra $70 can go to a beefier motherboard with a decent VRM, for example.
The official slide deck makes it clear that XFR means more than just an unlocked multiplier. It will allow automatic, realtime overclocking beyond normal limits with "no user intervention required".
AMD, like all companies, has often presented their products in the most favorable light in their marketing materials. But they generally do not lie outright about what features are or will be included.
Supposedly it should be the single core turbo, shouldn't it?What do you think the red line represents?
It should be pointed out that Nvidia has been doing the equivalent trick on their video cards since at least Maxwell. The actual boost clocks observed are often beyond the "official" boost level, even for reference cards.
Since BR shadow p-states allow clocking over base clock indipendently of the load if the conditions are met, so probabily also XFR is not bound to load...
Now, i am probably wrong anyways, but not for a minute i believe AMD can launch a product, even a great one, without marketing blunder in recent years.
Remember Raja, Crossfire scaling and "efficiency" at Polaris announcement at Computex? After that i lost any and all faith in regards toI guess the difference here is that the few tidbits of info regarding XFR have come from someone who has a phd in architecture design, they also happen to be CEO of the company that designed the chip....
Even when the speaker knows what he is talking about.So no marketeers with MBAs "filtering" the info!
It's written there, right in the middle.All core turbo?
I know, just trying to decipher what The Stilt is trying to say lolIt's written there, right in the middle.
What do you think the red line represents?
Anything above 4.3Ghz would be way above my expectations.
4.3Ghz+ with the claimed IPC would make Ryzen CPUs amazing value for all DYI market, where overclocking is the most common.
