I disagree. If Intel or AMD send their CPU with a high end Intel Z370 or AMD X470 chipset board with auto overclocking turned on by default in BIOS to reviewers its ok as long as the power consumption results too are measured with the auto OC on. If the user does not like the settings he can turn auto OC off and manually tweak clock and voltage. btw the whole purpose of high end motherboards is to push the CPU to its highest perf, within safety limits though. The option of auto OC vs manual OC is still with the user. Ideally the reviewer should post stock and auto OC perf and power results to provide the user with the information needed to go with one of them.
That isn't how reviews are done. Everything should be bone stock to eliminate any variables.

He did not perform OC, Now if those 5-8 % gains of 2700X over stock are real as said by CPC, this chip is a good improvement over Ryzen Gen 1.


This is quite funny because whenever Intel is going to release a new CPU with a merely 5-8% improvement everyone is blaming them for their laziness and poor improvement rate, especially when it's paired with an increase in power consumption!

According to CPC
5-8% of 2700X with XFR 2.0 Enhanced / PB 2.0 Overdrive over 2700X stock not over Gen 1.

NPRP bioses are required to have such features disabled.

GamersNexus did a MCE (Multi Core Enhancement) investigation of Z370 boards recently. MCE is not officially supported by Intel and in some cases blue screens can occur because the CPU is running outside of its safety margins. He found out that is was enabled in the review bios provided by Gigabyte:

https://www.gamersnexus.net/guides/3268-multi-core-enhancement-and-core-performance-boost-testing
GamersNexus said:
Then, after digging through old flash drives and trying to find revision F2, which shipped on the motherboard for review, we found the culprit: There is no MCE option in this BIOS revision, and although Gigabyte did later embrace that MCE should be disabled by default, the initial BIOS revision had no MCE option and MCE enabled, silently, by default. There was no way to disable MCE in BIOS revision F2. It was not possible to turn MCE off.

Does anybody know if Precision Boost Overdrive is an official supported feature within the safety margins of correct operation?

Interesting.
Latency for L3 cache at that frequency in just nice improvement.

Anyway this dude has messed up timings. There is no way that this act anything like good 3200CL15 timings. I get better read/write/copy results with 3200CL14... nothing special with timings (normal timings and achievable on better hynix or samsund e die). And for those who are questioning about my RAM, I can boot samsung save B die safe preset (@The Stilt ) 3333MHz at 2933/3000MHz yet not stable enough.



RTC


I got 165p with 3200MHz RAM at 4GHz in CB R15 ST. I would expect ~180p at 4.35GHz, anyway not claiming that he is a liar, maybe there are just few problems with XFR and X370.

Yeah, if you see markedly lower copy performance in AIDA's memory benchmark relative to read/write performance, then that's a result made with motherboard auto subtimings (or XMP which only sets primaries), which suck. Stilt's timing profiles with proper subtimings get copy performance very close to read and write in this test, plus a much lower latency result.

It seems there's a possibility for a sub 60ns result here if PR's memory controller can reliably work beyond 3466MHz while sustaining tight subtimings.

New Results for 2700X OC, AX 370
Stable all core at 4.25 - 4.3 GHz

CB ST 178/MT 1948
Memory Latency at 60.8 ns with 3600 CL14

Looks like 4.3 is the new 4.0 GHz.
But this chip does not have the annoying +20 degrees offset.



I never managed to get my 1700X to 4.0 GHz though.

I do agree in the sense that, it was stupid marketing to call Ryzen 2xxx a "tock",when in all fairness it's very similar to an average Intel "tick" in performance albeit with a smaller process shrink ( and definitely less than Ivy Bridge, in architecture ,which was called "tick+"). Perhaps AMD expected more of the process, Say 4.0/4.5?

But you know more than enough why people were pissed @ Intel's tiny performance increases (at least before Coffee Lake). Haswell was released in Q2'13, Devils Canyon in Q2'14, Skylake in Q3'15 and Kaby Lake in Q1'17. That's such small increases 4 years In a row (5 if you include Ivy Bridge). I'd understand your ire if Zen 2 with the first meaningful process improvement and architecture changes undelivers similarly, otherwise it seems like trolling.

This looks very very good and pretty much what i was hoping for (for at least some improvement in memory OC). The 3600 CL14 was unstable in Cinebench though, but that might have been because of low SOC voltage.

So, Ryzen 7 2700X has Cinebench R15 single thread that's close to of those of Core i5-8600K?
Looks that way. Something above 4970K and slightly below 6700K or 8600K. The scores are close enough though so milage might vary.

good morning
Yesterday after the tests I discovered why the pc crashed
The corsair h90 pump was at minimum speed
This morning I'm re-testing now I can stay stable at 4250mhz to the core
with 1.38v
An excellent result for my expectations
With a custom heatsink, I think 4300-4350mhz (all core) is possible (silicon lottery)
In default (4350-4375mhz) voltages are over 1.5v, I do not like to use too much voltage
Also consider that the gigabyte bios for this cpu does not exist
With new bios, with 3600mhz ram support and over , we will have incredible boost.
My ram is 3200 c14 but can also go to 3600 c14.14.14 without problems
To be correct ,I'm not under NDA, I have not signed anything, so I can do what I want
voglio

So we are probably looking at :
- 3200CL14 ~ 65ns
- 4,2GHz @24/7

Which makes R5 2600 great deal. R5 2600 mastech MT performance (except AVX) clock per clock and since OC will allow to achieve 4,2GHz vs 4,3Ghz on i7 8700 this can be great decision. i7 8700 LLC (as far as I know) is clocked at 3,7GHz so below 50ns on DRAM is quite hard to reach unless you go with really good dram.

Depends on your definition of 'close'. Just for reference I did a 4.3GHz CB ST run on my 6700K and got 190, so Ryzen 7 2700 is within ~7% of Sky/Kaby/CFL clock for clock, at least in Cinebench, that's quite impressive actually.

Who here thinks 4.5GHz is a real possibility (with sensible voltage), or do you expect closer to 4.3GHz? Of course time will tell, just asking for your predictions

Unless the process improves 4.5 isn't very likely IMO. Considering the Italian overclocker experience 4.25-4.3 Is the most probable with <= 1.39V. I might see some golden samples or Threadripper chips hit 4.5 GHz (with similar voltages people are using to hit 4.2 on current Threadripper), but that won't be common.

I'm also pretty sure, that if the process matures and a newer stepping by some miracle is able to reach 4.5 Ghz OC, we'll also see a 2800X with similar turbo clocks.

Maybe on second generation Threadrippers. People with 1900Xs and others already achieve 4.2GHz on all cores and I think I've even seen some do 4.3GHz. I think most 2700Xs will do 4.3GHz or below, lucky ones will go a bit further, perhaps. I wonder how far the 2600 and 2700 will OC...

I am still really interested in the RAM support and how the lower latencies will affect performance.

Would it make sense for GloFo to keep developing the 12 nm node, when they have 7 nm so close? Almost like 6-9 months from now assuming its not a repeat of their earlier process migration.

I am actually expecting an AT article like this one to pop up
Maybe they won't do it this time, to avoid sales cannibalization.
The Zen articles from AT were really interesting. Looking forward to the juicy writeup for the new micro arch.

You will most likely not see a 7nm Ryzen before late Q2 2019. If a new stepping can bump up max clocks by even 200 Mhz it might be well worth it against the upcoming 8C CFL which will be a OC monster capable of 5 Ghz.

L3$ latencies at that freq?

I am reading some opinions on other sites and people wanted to upgrade from ryzen 1800x to r7 2700X. After that OC on YT they are a bit disappointed with OC. While 4,5GHz seem to be impossible main point is that 4-4,2GHz is possible with actually good voltage.

While I need 1.575V LLC 3 (~1.54Vcore all core load) to run stable 4GHz on my R7 1700, we might actually see 4GHz at 1.3V (load) on R5 2600 and R7 2700 which seems to be very impressive. Maybe some people didn't point out that with higher RAM OC is really hard to keep stable high frequency.

I can see some cheap build with R5 2600 on cheap cooler 3,9-4GHz on cheaper motherboards with DDR4 3200. You might be surprised, but I think that running i7 8700 on cheaper (cheap VRM design) B360 might give you headache. Maybe it will run only at 3,2GHz.

The question is do they have other customers for the 12 'nm' node. I seriously doubt we'll see another stepping since GF will be all in for maxing out production and securing additional foundry customers over small performance bumps. That said, the yield curve could get better over the next year and higher clocks might be easier to hit - especially for cherry dice.

These frequencies are amazing! With it tuned like this I think it'd make a lot of sense to have native dual core die APU. Something like 2c/4t and ~6CU, which I think would be close to minimum die practical area ~110 mm2.

I would love to see 5GHz and 4000MT/s dram on ryzen.

L2 cache latency from 4.3ns to 3.0ns,L3 cache from 11.2ns to 9.4ns.

I thought only L3 was improved, but chech out L2 latency improvement.

I'm expecting Thread Ripper 2 will have xfr2 to 4,5 GHz with 4,2 GHz base clock.

I wonder how p state oc will go with the new turbo, depending what is exposed that could be the way to get to ~4.5 single thread ~4.2 all threads.
