AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[Journey]

Insane ! Specially if slapping in say Vega 56 or little Navi for 1440p gaming ! Savings should allow it and compete with next gen consoles

I suppose given the pricing of 1xxx parts, the extra 'free' performance at these prices will be great, especially as the 9400F is such a compelling choice for a budget games machine at only £140, it makes choosing a 2600/X easier if very budget constrained, and as you rightly said allowing that saving to be put towards a more capable GPU choice. I'm not sure how much lower the 1xxx parts will go as £130 for an R7 1700 is already a bargain, maybe ~£119, or ~£109, 8c/16t for that money would really be an eye opener for the low end of the market (not just gamers!)

Precision Boost is AMD's answer to Turbo Boost. The first iteration worked similarly to Turbo Boost with defined frequency tables. The second one, currently used, is a lot more flexible, altering frequencies with a 0.25 multiplier for finer control.

Precision Boost Overdrive is available on all Ryzen 2000 series processors with an "X" suffix, but you need an X470 board to 'activate' it. It will allow an extra 100 MHz on top of the maximum all-core frequency of Precision Boost, when the time presents itself.

One of the things that PBO checks is the capabilities of the mobo, which is likely why we're seeing "excessive" VRMs on the X570 boards. Manual overclocking is now for the dodos, hence the race not to be the bottlenecking factor IMO.

Incorrect, PBO is only officially supported on TR2 however some board partners have enabled it to some degree in the BIOS for Ryzen, PBO settings allow you to increase the thermal and voltage limits that PB uses, while the "X" suffix denotes chips that use Extended Frequency Range, the equivalent of Intel's Turbo.

Wrong on both counts i'm afraid. PBO works on X370 as well, been working fine on my CH6 since the day i dropped my 2700x in. With good cooling, PBO allows a lot more than just 100Mhz extra, look at my sig. Mine boots straight to 4.25Ghz all core all the time unless it's a very hot day, in which case it boots at 4.225Ghz all core.

How much extra voltage does pbo allow for on current chips, still within safe limits?

Yeah, this. The CH6 definitely had it. The others just had the scalar that... didn't work very well.

I will be publishing a full review of a Ryzen 3000 processor with x570 motherboard today or tomorrow....

Using PBO and PE level 4 on my CH6 and a 2700x, running Real Bench using 4x8Gb sticks of ram at 4.25Ghz the Vcore pull is 1.369v. Much the same running OCCT as is Prime95.

In this thread ?

Super early review awaybreaktoday?!!!

 

[awaybreaktoday]

In this thread ?

Yes..

 

[jigger]

It's actually the holes on the i5 against the holes on the AM4. Won't work, for sure

100% works.

 

[kitfit1]

Yes..

Will be looking forward to tomorrow then

AMD clearly state that PBO is a new feature first introduced with TR2 on X399, which was August/September 2018, ergo well after the 2700X.
PBO automatically adjusts the limits of PB2 outside of the set limits. It constitutes overclocking and thus voids warranty. Neither PB2 nor XFR2 are deemed automatic overclocking; they are merely using AMD set limits.
PBO is designed to allow automatic overclocking outside of these limits, whilst also allowing the benefits of the other smart features...something a manual overclock would disable.

What shenanigans is this.

It is annoying shenanigans if he prefixes it with an [insert your own annoying Scottish accent when reading it] at the start of the review.

Nice thick layer of liquid metal between socket and CPU base should ensure a good connection.

100% works.

Even if you somehow successfully manage to connect the 1151 pins on the i5 with the 1331 pins on the AM4, you'll need to write a new BIOS for the mobo with support, as well

I'm guessing you guys missed the AMD slide during the Pinnacle Ridge release in April 2018?

Yes, it works with X370 boards as well, however my point was rather to point out the need for an X-series chipset, rather than specifically the X470. It just so happens that the X470 chipset came to my head due to the 2000 series shipping alongside it.

PBO settings allow you to increase the thermal and voltage limits that PB uses, while the "X" suffix denotes chips that use Extended Frequency Range, the equivalent of Intel's Turbo.

Limits are increased, but there are still limits in place. Those limits are merely identifying the capabilities of the VRM design and not exceeding a threshold. It is a clever technology.

Precision Boost 2 and XFR2 work together to identify more capable cooling, to allow the processor to achieve that maximum all-core frequency that AMD advertises. Together, they are akin to Turbo Boost 2.0, while Precision Boost Overdrive is akin to Turbo Boost Max 3.0.

With good cooling, PBO allows a lot more than just 100Mhz extra, look at my sig. Mine boots straight to 4.25Ghz all core all the time unless it's a very hot day, in which case it boots at 4.225Ghz all core.

The maximum all-core turbo is 4.30 GHz. For the 2700X, PBO extends to 4.35 GHz. The 2950X has the highest PBO frequency of 4.50 GHz.

Precision Boost 2 is entirely opportunistic. There is no longer any distinction between single-core and multi-core turbo. There is no frequency table; only two defined maximum values for PB2/XFR and PBO. Your result entirely depends on what your hardware deems is possible by your specific system. What you achieve isn't what someone else achieves, and vice versa.

I'm starting to get curious as to when exactly Zen2 is faster (or actually as good) than Intel during gaming.

Because I'm not sure I can get a 3700X or 3800X for less than a 9700k (which probably overclocks much better).

The very same thought is starting to concern me, I've had a 5960X forever and was set for the 3800X/3900 but it looks like a 9700K easily compete with these possibly more expensive AMD offerings in games. I want to believe but unless AMD rule Arma 3 I'm going to stick with Intel. I didn't expect to be typing this now but I already have a very capable 8 core and I'm doubtful of what Ryzen 3000 can offer me.
