Saw that, the 4700G looks like a fun CPU to play with 2k+ IF, 4k+ ram, 8/16 and a high enough stock turbo limit that a mere 106 bclk will give very good single core performance. Not to mention, less hot l3 cache to cool, with igpu disabled there will be a lot of dark silicon to help sink heat and make cooling easier. Yes please.
I forsee a lot of tweaked 4700G setups smacking the 3700x/3800x/3800xt around lol (probably why they're dragging ass on releasing it).
I mean I would love to have 2k IF 3900xt with dual 4.7 capable CCDs but...
Regarding 2k IF on xt refresh... Not a chance if going by the tests listed so far. All of them (for all 3 chips) are 1500, 1600, or 1800 memory except 1. That 1 is 2010 ram, but not synchronized IF, obvious by the lack of score efficiency at 4525 it scores like my 3900 at 4300.
To me it seems the CCDs are not what's holding back IF, it's IO die/substrate/motherboard. I suspect this is why enabling LN2 mode in AMD section can stabilize 1900IF on system that otherwise cannot run 1900IF, as it will be increasing hidden board voltages even if all user configurable voltages remain identical.

|nick name||I still can't figure out why Rzen Master shows my SOC voltage at 1.081V while HWiNFO shows it as it's set in BIOS. Does anyone else suffer from this?|

I do not have the fabric clock bug on the 3101 bios. Sleeps @ 1868 and stays 1:1 after waking up.
3101 effectively makes the C7H the best Ryzen 3000 PBO board on the market.
Force OC mode disable + PCIE 3 being less finicky with bclk + bclk at 104.
C8H has all the same ability except I've read a lot about PCIE 4.0 not tolerating raised bclk well.
549 R20, 221 R15 single cores 566.8/193/576 cpu-z single scores totally stable. No EDC bug, PBO enabled but with stock values of 95-140-142, scalar 8, auto OC 200, LLC 2, auto voltage.
This configuration allows the core to boost beyond the 4650 limit because it disables the multiplier adaptation typically applied using bclk OC when force of mode disabled is set to enabled.
It's visible immediately in the "base speed" which for me shows as 3933 instead of 3800 and boost speeds are peaking at 4758 with sustained multipliers bouncing between 45.25 and 45.75 @ 104bclk, so...4706 to 4758.
Other boards and the C7E with force OC mode disabled set to disabled, will adjust the multiplier down to 37, or whatever gets it closest to 3800 base speed.
I would not believe this worked except the scores clearly reflect the speeds beating even 3950x single scores indicating it is, indeed holding boosts beyond advertised max.
When exceeding 104 bclk, the CPU gives all the tell tale signs of too little voltage for a given speed aka needs more voltage because it's boosting over where my chip is stable. R20 crashes with the warning msg box, and other benchmark crash in the same way the do when they're "just" under the required voltage to be stable.
I suspect the 4750 @ 1.5v is essentially "the wall" for Zen 2 cores, reflected in the 3800xt and 3900xt revised speeds and the 3950x. I don't believe AMD there's a "improved process" more like "excess of 3950x CCDs to clear out before Zen 3 launch".
See CPU-Z link in sig for example of why bclk+force oc mode disabled+pbo = win
*edit Its not fixed for me still drops fclk and uclk when waking from sleep to 1800/950 from 1900

Will definetely be a Zen 3, looking forward having IF above 2000MHz Why would they spec RAM speeds above 5GHz on the new mobos if something wasn't coming?
Those APUs may also be why new mobos support such fast RAM.

No problem for the Geekbench trick. I can't remember who taught it to me.
And two good CCDs is just a hope that maybe the process has matured enough that they aren't really making any "bad" ones anymore. Not that I guess it really matters to me as I don't plan to buy anything until Ryzen 4000 comes out. Or maybe even 4000XT.
