So far as I know AMD doesn’t publish one and my experience is different motherboards and BIOSes use somewhat different values. From what I know your table’s commonly given for Zen 3, 4, and 5 parts but the defaults for 105 W TDP are TDC = 95 A and EDC = 140 A.
For the 9900X I use ASRock’s B650 3.08 BIOS (AGESA 1.2.0.2) goes with
| TDP, W | PPT, W | TDC, A | EDC, A |
|---|---|---|---|
| 120 | 162 | 120 | 180 |
which seems to be the same as the 7800X3D defaults.
AMD’s also used 95 W TDP at times, which at least one pre-release article had the 9600X and 9700X on. IMO that would probably have made more sense than the 65-105 W back and forth.
All the Zen builds I’ve done are dual CCD and I haven’t seen anybody look at this particular angle, but that seems plausible. Most of the constraints you’ve hit here are why I tend not to push memory speed and voltage in favor of focusing on tighter timings. Partly also warranty thing plus ability to rule out overclocks as the cause of occasional weird system glitches as well as constraining thermals.
For 9900X perf I’ve gotten about +9% from tightening from JEDEC timings to M-die primaries and pulling in secondaries and tertiaries at DDR5-5600 while leaving margin for aging. Might pick up an additional percent or two if I tinkered with it more.
Don’t know that anybody’s broken it out. Comparing SoC power traces for the same workload at different DDR speeds and timings should yield an estimate of how much extra power pushing up the DIMMs requires in the UMC and IFOPs. Which doesn’t answer the question as posed but is probably more useful to PPT budgeting
Most differences I’ve seen reported are small enough it seems to get down to what the individual silicon likes and how good the person tuning it is at taking usable margin. If FLCK’s stable at 2133 then 6400 with tighter timings looks quite competitive. If you have to break 1:1 then probably 8000. None of the 6400-8000 comparisons I’m aware of have reported power consumption by die, so they’re likely constant PPT rather than constant core power results.
It’s out of reach to me as I’m on 2x48 GB DDR5-6600.
