“You know, with our boost algorithms, we eke out just about everything you can get. So maybe a couple hundred megahertz. With the 65W parts you’ll get a lot more because their specs are run with a lower power. So you can overclock the thing, get all the power of it, and, obviously, you get more headroom out of it.”
As expected 3800/3900 will be 2700x situatuion aka "overclockers dream"
. I think 12x4.5 is max i will be able to get on my custom water with 230wTDP
But that means you'd have to be able to set ~+300mhz to ~+500mhz before matching the higher tier chips, then more to actually make it worthwhile. And you haven't got the extra physical resources like extra L3 if you do get there?
I would have assumed the extra TDP would afford you a better starting point, or at least scales with the expected base clock. Assuming the base clocks are indicative of an abusive full thread load, it seems to make sense that the TDP of the 3700x @ 3.6 is 65W and 3800x @ 3.9 is 105W?
So I'd assume, by the time you can add enough of an offset to match the 3800x all core, your TDP is likely to be identical?
and likewise, for a 16 thread load, the 3900x and 3950x are likely to be making the same TDP, though obviously for higher thread loads, they'll begin dropping to lower clocks to stay within envelope?
Have no experience with previous Ryzen - when you use PE/PBO does it truly unlock the algorithm? i.e. leaving you to balance thermal/voltage management only and no longer having to concern yourself with TDP/current limits?
that actually makes me think the 3900x looks quite good - a 100mhz trade off for an additional 8 threads loaded...
