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

It's just the human brain's need to have this big round number to make us feel better.
That's not exclusive to numbers. :D
The node is a high performance node and there has been information released from TSMC quoting 5ghz performance reports on their 7nm.
The problem is nothing manufactured on TSMC's 7nm node (A12 & Vega II) has so far managed to achieve more than a 200Mhz up lift from previous gen (12/14nm).

If that is the same for ryzen 3000 we can only assume the engineering sample which went up against the 9900k was clocked around 4.5 ghz in which case you could guess the ipc gains are considerable for it to have edged a win with a 500mhz deficit...

The 9900k was running at default settings which would be 4.7GHz for a multithreaded program like Cinebench. Although Intel's devious marketing department boasts a turbo clock of 5GHz, that's only applicable to two of the cores while the other 6 cores are clocked much lower.
 
While I don't hold stock in that type of leaks credibility if it was like the 2700x we'd see lower clocks than stated not higher, The 2700x was officially quoted as boosting to either 4.3 or 4.35 on a single core, I forget which, but for overclocking 4.25 to 4.275 is the best I've seen shown as stable, Mines at 4.25 under an AIO and it has good temps, I can boot it up with a 4.3 overclock but once it's running at load it crashes, I haven't seen better with proof anywhere. Plus we see unreliable results as these show where my overclocked to 4.25ghz cpu is reported as running at a 4.3, 4.4 & even 4.7ghz. https://www.3dmark.com/compare/fs/18261261/fs/18352449/fs/18352509# These are all unreliable results not true examples of Ryzen's potential so rather than be disappointed we'd all be better off keeping our expectations in check. I'll be very happy if I can get a cpu capable of an all core overclock at around 4.7 or 4.8, and that's where I'm expecting the flagship to be.

I've been quite optimistic about Zen2 myself. I don't see why AMD can't move to 7nm and improve their architecture at the same time. If Intel can get 5Ghz, I don't see why AMD can't if they put their mind to it.

I spent ages tweaking my 2700X after getting it, initially with all core OC's of up to 4.25Ghz, stable as a rock but a bit too warm for my liking. I'm on air using a Noctua though, not an AIO or loop. After weeks of playing around with the CPU and RAM timings I ended up switching back to XFR and just upping the BCLK. Now I get perfectly stable boosting across all cores at 4.5Ghz with lower temps than a 4.25Ghz all core OC. Benchmark results were better too, which surprised me. Think I've only ever seen the CPU hit 71C at full load.



Only thing that concerned me slightly were peak volts but they're not sustained and I've just come to terms with the fact that it could degrade the CPU over time. The 4.5Ghz single core boosts make up for it as far as I'm concerned and I've had no problems so far. Hence my thinking about the 3850X if indeed it does boost to 5.1Ghz. Wishful thinking maybe, but I can hope. :)

EDIT: Actually thinking about it, BFV peaked at 74C I believe.

Have done similar but I didnt like the voltages so I just put it back to stock. :)

What board?
104 FSB?
Any voltage tweaks?

I've done a good bit of playing around with mine and I've cooling for days but... it doesn't seem to want to go beyond the 4.35ghz boost they're rated for.

On a fully patched system for meltdown etc. that is actually quite plausible.

what are the peak volts?

It would seem these chips can happily use quite high voltages given XFR even without PBO can hit 1.45v.

I'd expect R3 to push clocks a little higher than 200Mhz due to the fact that the A12 and Vega II are fairly high in transistor counts (higher densities = more heat) however i can't see it being 800Mhz higher, maybe 400Mhz at a push.

I've not seen the leak where an R3 edged a win over a 9900k, I'm guessing from what CuriousTomCat said it's a Cinebench result, if so it's sort of what i was referring to earlier about conflating IPC with performance and clock speed, yes it's beaten an 9900k but i wouldn't be surprised if it actually did that with a 100Mhz deficit, simply because Ryzen performs better in multi-threaded workloads than Intel on a clock-for-clock and core-to-core basis.

AMD aren't doing the fabricating so their hands are tied to a certain extent, yes they'll have plenty of input when it comes to the design rules but ultimately TSMC say what can or can't be done, AMD may have tweaked the design to work better within TSMC's design constraints but ultimately a fabless semiconductor company is never going to be able to match what a company with its own fabs can do.

As much as we all like to laugh at Intel for their delayed 10nm they've always ruled the roost when it comes to fabrication, they still do despite the hiccup with 10nm, that's not to say Intel are superior in every way as their over reliance on improvements from shrinking nodes and fabrication improvements have caused them to almost completely ignore improvements that can come from design changes, they've been using the same basic 'core' design with a few tweaks here and there for over a decade whereas AMD has been forced to think outside the box.

X470 Aorus Ultra Gaming, BCLK103.5, both XFR and PBO enabled, slight negative offset on VCORE but it does touch 1.55 on occasion.

Weirdly in the BIOS it says BCLK is bouncing around between 103.8 and 104.2, but it’s manually set at 103.5.

I remember reading about upping the base clock to improve it's single core performance elsewhere.
 
I always have a little increase on the BCLK, somewhere between 102-104 is normally OK, unless you have other multipliers available that enable to push it even higher it can start causing stability issues when pushed further.

I was using 112 with the 1800X at the start, when the RAM speeds were real bad. But NVME had issues 106 and beyond lol.
 
I've not seen the leak where an R3 edged a win over a 9900k, I'm guessing from what CuriousTomCat said it's a Cinebench result

Wasn't a leak, it was a live demo during Lisa Su's CES Keynote. Carefully crafted like-for-like comparison saw an engineering sample 8-core Ryzen 3000 with an undisclosed clock speed beat a stock 9900K in Cinebench by a couple of points. And by stock I mean the 9900K was allowed to do its thing (apparently) and go all-core boost to 4.7GHz. Allegedly some tech commenters have taken so inside information and calculated the ES Ryzen's clock speed and IPC gain. but I can't find the sources now and can't remember what the numbers were. But that ES Ryzen was only using a single chiplet with space for a 2nd clearly visible (including PCB traces for it).
 
Educated guesses were pegging it as an 8c16t @ 4.2-4.4Ghz and 65W TDP chip.

Rumoured to be something akin to the Ryzen 5 3600 $180 chip.

Be nice to see some proper competition going on in the 8c/16t area - when I upgrade I want a proper jump from my current 4c/8t setups.
