AMD demonstrates Ryzen 9 5900X prototype with 3D V-Cache stack chiplet design

You likely have no clue about the power use of AM4 based parts, call it nit picking, or maybe just admit you are wrong like a grown up.
The entire premise of your previous post is nonsense based on a fundemental misunderstanding of the hardware you're talking about. Hardly "nitpicking" is it?
Soldato
I really don't think that comparison is fair or remotely accurate. 5700G is a monolithic chip, 5800X has 2 dies and an interconnect; it's the design and implementation of the Matisse package that takes 20W, not a piddly 16MiB of cache.
Soldato
If you are an example of a 'grown up', I'd rather not
Being unable to admit you are wrong, then trying to deflect it back at the person who calls you out, we can now all see you aren't one.
Throwing around random numbers and complete guesses with a few random slides/images doesn't help if you don't understand what you are talking about in the first place.

That's coming with Zen 4, 6nm I believe (so essentially a denser 7nm) with 5nm chiplets.

There is a better way of working this out.
Core power 83 watts, SoC power 9.5 watts, total 92.5 watts, total package power 107.2 watts, cores + SoC / by Package = 1.158 (15.8 watts) for the L3 and interconnect.

That's wrong i have percentages stuck in my head, its about 14.8 watts.
14.8 watts is not bad for the L3 cache + interconnect (I think your method of working this out is more precise 
). I suppose a 5950X with more L3 cache might be doable. Probably won't need to wait long anyway, likely 1-2 months.
I still think shrinking the I/O die to 7nm would be a good idea though, if it improves total power consumption.

Yeah.
They all use about 130 watts package power out of the box, i have manages to reduce my cores power by about 22 watts with +100Mhz brining the cores power down from 105 Watts to 83 watts and boosting from 4.85Ghz to <4.95Ghz or 4.65Ghz to 4.75Ghz high stress loads.
Curve Optimiser: Negative 15
CPU boost overclock override: +100Mhz
Precision boost scaler: 4X
The socket limit is 142 watts. that gives them about 10 watts to play with and my CPU is a better than average sample, if AMD did some better binning, and 18 Months later 7nm should be yielding better quality silicon..... so i don't see why AMD couldn't fit that extra L3 on it and perhaps even get a little more out of the cores, like i have.

One more thing, remember the FX-9590? that was also on a PGA Socket, AM3+, it had a package power of 220 Watts.
AMD are willing to throw the PGA 142 Watt limit out of the window, it literally fried cheaper not well made boards, mainly those from MSI but i ran one for a year OVERCLOCKED to 5Ghz all core on my Asus Sabertooth 990FX Rev2 and it never bothered it in the slightest.
There is no reason why AMD can't release an X590 board with higher power directives for vendors to adhere to, that would unleash the high core count Ryzen 5000 which are capable of running much higher clocks all core than they currently do with the 130 watt limits in place.

Has it been confirmed these are not on 6nm perhaps that's how they will solve the power issue if the process is slightly better ?
Caporegime
Dunno, where do you hear that?

Just thinking not much has been said about these bar they are coming and production starting Q4 2021 - the new 6000 series mobile is supposed to be on 6nm so thought maybe they will release these as 6000 series desktop.
6nm would be ideal as they won't have to sacrifice anything to provide the extra cache.
Probably wishful thinking though and just on 7nm
