It was- but it still says Precision Boost 2 "continues to boost—on any number of cores— until reaching the maximum clockspeed printed on the box". I'm all for it- but AMD is likely to set the limit (clockspeeds printed on the box) at what was tested to be achievable at said TDP at 100% load. Instead- if Zen+ is capable to clock higher at higher power use than TDP- they could follow Intel's example and set maximum boost to go even higher when load is less than 100%, and still fit into TDP.

im all for it also but in my view up to 95W TDP it would turbo to as its writen on box for turbo, but if you have good cooling XFR should be able to push frequncy higher only limiting factors should be your cooling and/or voltages

~5.5% freq uplift.
.

At 0.9x the R5 1600 TDP, that s the margin left by the 10%+ perf improvement at iso frequency provided by the new process....

The R5 1600 did more or less reach 65W under Prime 95 or X264 encoding, this way the 2600 should be slightly below 60W in worst cases.

I have to admit, 200 MHz is a little... underwhelming. ~5.5% freq uplift.

I don't know how you counted, however this is exactly 6.25%.

Btw, I think it would be not a final base clock of Ryzen 5 2600 - I'm expecting 3.5 maybe 3.6 GHz.

AMD Ryzen 2 Processor Leaks Out on X470 Motherboard – Includes Ryzen 5 2600 Hexa Core and ASUS’s Crosshair VII Hero Motherboard
The processor leaked out in SiSoftware Database and is part of the upcoming AMD Ryzen 2 family. The codename for this specific chip is ZD2600BBM68AF_38/34_Y and it will be known as the Ryzen 5 2600 which means it replaces the Ryzen 5 1600 (1st Generation Ryzen). Based on the naming scheme, this is indeed a second generation Ryzen processor which comes with 6 CPU cores and 12 threads. The clock speeds for this chip are mentioned at 3.4 GHz base and 3.8 GHz boost clock. In terms of cache, we are looking at 16 MB of L3 and 3 MB of L2 cache in total. The processor will be a 65W chip based on the codename which falls in line with the Ryzen 5 1600 with a similar TDP range.

Looks like a 200MHz increase over base clock from the 1600 to the 2600. Not much gain there. The 10% performance increase is looking pretty like a pretty good ballpark number. Hopefully a precision boot 2 will give it a good bump in single core boot speed. Lets hope for an optimistic 4.5GHz single core boost clock.

Interesting results. I wonder what were the average clockspeeds for the 1600 and 2600 in those benchmark runs. A 200 MHz increase in peak clock is getting the 2600 nearly 10% in every benchmark there (which admittedly is a pretty limited set of benches). Gotta wonder what's really going on there.

@The Stilt Will we get cTDP with Ryzen 2000 CPUs? What about user-configurable cTDP? The specs on AMD page seem to imply that the APUs will have cTDP.

@The Stilt How does cTDP work exactly in relation to boost tech in Ryzen? If I increase it above the TDP, would there be a point where my cores would constantly XFR?

On Ryzen 2:

AMD's James Prior at CES on 8 min 20 sec:

"Yes we've got some early samples going out to key partners.
They are not full performance or, you know, final shipping products,
but we are starting that engineering effort ...."


https://youtu.be/7MPxN6MEgbk?t=8m20s

Exactly these are QS and not final production chips. For comparison here is the speeds on AMD Ryzen APU QS chips.

https://www.reddit.com/r/Amd/comments/7ooy69/ryzen_desktop_apu/

3.0/3.3 and 3.3/3.5 Ghz. The final production chips were R5 2400G 3.6/3.9 Ghz and R3 2200G 3.5/3.7 Ghz . I think we are going to see a R5 2600 launch at around 3.6 Ghz base and 4.0 Ghz boost. The R5 2600X with 95w TDP, Precision boost 2 and XFR2 is going to be around 4.0 Ghz base / 4.4 Ghz boost. XFR2 is likely to bring another 200 Mhz due to improved Precision Boost 2 and 12LP high performance process.

Yeah, given how highly clocked the APUs are, I would not be surprised to see the 2600 stock clocks a bit higher than 3.4/3.8. If I were buying Ryzen, I would be far more interested in increased OC headroom. That's where the real value of an unlocked CPU with a capable cooler included comes in.

If you're willing to overclock, the 2600 will offer incredible value, much like the 1600 before it.

Summit Ridge QS / PR had the same clocks as the release parts, the only difference was that the model names were not decided (and a roadmap code was used instead).

ZD3406BAM88F4_38/34_Y == 1700X
ZD3601BAM88F4_40/36_Y == 1800X

Those specific QS's appeared closer to launch, after Lisa Su revealed the 1800X, IIRC.
I do remember that no QS had 4GHz before the reveal from Lisa Su, which happened a month or so before launch. People were surprised by the 1800X reaching 4GHz since all QS's previously haven't been at that clockspeed.

HOWEVER: Important to remember that they might have been in the wild but just never discovered before the 1800X reveal.

They came available in december / january, so the time window matches as well.

IIRC the Turbo / XFR will scale with the power limit (increase), but there are several other variables which affect the behavior as well (current, temperature and utilization to some extent).

So that does not mean that PR has to have the same specs. btw here is a little bit from James Prior of AMD

https://www.youtube.com/watch?v=7MPxN6MEgbk&feature=youtu.be&t=8m20s

"Yes we've got some early samples going out to key partners. They are not full performance or, you know, final shipping products, but we are starting that engineering effort ...."

I've never seen any AMD PR / QS chip which wouldn't have had the same specs as the final retail ones. Not much point in calling them as "production release" or "qualification sample" parts otherwise.
Engineering Sample and Prototype status parts are a different story entirely, obviously.

You probably realize that the statement from James is a generic one.

But we'll see if the R5 2600 indeed has 3.4GHz base and 3.8GHz maximum single core turbo (non-XFR for both counts) or not soon enough ;)

People here keep saying that Zen+ is going to be ~10% faster.

Was this ever officially said anywhere?

Or is this: Somebody uncle's 5th cousin-in-law said so?
