A return to heatpipes and clips? Huh? I wonder if that slide is true or not, seems potentially fake.
How can it be fake when the slide came from AMD?

Pinnacle Ridge AGESA (which is rolling out to all AM4 motherboards these days in preparation for Ryzen 2000 series launch) has finally fixed pstates, you can set them to whatever you want in BIOS without breaking any functionality. Then you can enable cstates (should be enabled by default, but it doesn't hurt to force them on) to let the hardware properly idle, and use an appropriate power plan in Windows.
Here's the result:
- P0 is set to 3.8GHz and 1.375v (no LLC, droops down to ~1.31v under P95 AVX small FFTs load)
- vSOC is set to 1.1v to support 3466MHz memory speed, vDIMM 1.425v
- Ryzen Balanced power plan with CPU idle speed set to 0% instead of 90% because I'd like to let Windows use the entire clock speed range
See, proper idle (hwinfo managed to "detect" P3 at 0.4v) with overclocked speeds. You could more or less get the same result since launch day on the C6H with voltage offsets and other workarounds, but thankfully now it's much simpler and can be done on every board as far as I'm aware.
Anyway, having cstates enabled lets Ryzen take control of power management all by itself and that's what you want to do in this platform. Entering OC mode doesn't disable power savings.

I'm old fashioned and that's why I take that 90% idle down to 0%, but it's not needed.
Obviously, power management this advanced is miles ahead of any faildozer part ever made, and Pinnacle Ridge is probably going to make even more improvements in this area.
JustFinishedBSG said:Please buy CPC if you are French (online if possible because of their distributor problems... ) but:
According the CPC, the X470/B450 and X370/B350 chipsets are ENTIRELY IDENTICAL, they are literally renames. XFR2 Enhanced and Precision Boost only depend on the board but because not all old gen boards were up to spec AMD wanted to avoid a situation were some boards had XFR2/PrecBoost and some board didn't and decided to rebrand the chipset and impose more stringent standards.
They are supposedly dynamic based on the headroom available. Though still restricted seeing how the leaked slides points to "XFR 2 Enhanced" and "Precision Boost Overdrive" unlocking even more headroom...Are 'Precision Boost 2' freqency targets pre-programmed and static?

That's quite a hard work for A320 board.Some info about the CanardPC article from this thread.
Latencies should be really good, especially if these chips support 3466+ Mhz more widely. Precision Boost 2.0 also seems very nice (especially when considering that the benches were run on a A320 chipset:

No, all three modes have the same max clockspeed. XFR 2.O and Overdrive just increase the limits so that when you load more cores you don't lose as much frequency.So with Precision Boost Overdrive and XFR 2.0 Enhanced we could see 4.5 GHz SC boost, when not thermal constrained?
Looks like low 60s ns Latencies possible at > 3200 MHz , tight timings?
With a faster RAM kit and 400 series board the review might have looked a bit different.

There is some new info on videocardz.

Temperature, Power, and "Reliability" whatever it means in practice.Which limits are in effect for Precision Boost 2 at low core counts? They don't include power because 2 cores at 4175 MHz using 105 W (the TDP) doesn't sound right?
Now, you have to remember that CanardPC uses an A320 motherboard for testing.
You would think that a magazine about PC hardware would at least buy a proper X370 motherboard for testing.
