*** AMD "Zen" thread (inc AM4/APU discussion) ***

[harney]

Yesterday the guy run a similar benchmark at 1080p with the GTX1080
You will see the 1700 @ 3.9 matching the 7700K @ 5ghz on all benchmarks across the board (some loses 2-3 fps, other wins 2-3fps). And if you see the Ryzen CPU you can run 2 games on it because half of it is idling.

Its a good point the ryzen is not even been fully utilised as the 7700 is all most at peak ...maybe the driver from M$ re the scheduler may resolve this will see

It was posted few pages ago, and created a heated discussion. Especially why the Tomb raider is running DX12 on 7700K and DX11 on Ryzen.
Imho we should be looking for 2560x1440 not 720p. Who's gaming with a GTX1080 at 720p? All of us using it at 2560x1440 or 4K where the Ryzen CPU is far stronger than the 7700K or my 6700K.

This thread seems to move very quickly, its a bit hard to keep up at times.

The DX12 item is just a human error, I don't believe any harm was intended. I 100% agree, as I commented in another thread, if you are spending all that money I want it to run at it's native res (Monitor) with all the bells and whistles. Unless its professional gaming I don't see the point of running at 720P even then id find it hard to believe they would run its at that resolution. However, I am not a professional gaming so I wouldn't know.

Once the little bugs are ironed out its going to be a very impressive piece of hardware, as its effectively killed X99.

Not

Not all of us. Some of us are using at 1080 at 1080p because we're running 144hz monitors.
For that reason I don't think ryzen is for me which is a disappointment as I was really looking forward to this being able to compete with Intel's offerings at every level, not just when smt is used.

If you're primarily gaming and at 1080p I'd definitely hold off on Ryzen until at least the 6c/12t chips come out. By then Windows will be patched to fix the SMT issues and motherboard BIOSs will have matured a lot to improve stability and performance. Better to make a decision at that point.

We put the spare cpu in and still 0d error so it's either the board or the ram, there is nothing else left it can be

Yep. By elimination that should the conclusion unfortunately.

Have you looked on other forums see if any body else having the same issues with the same parts

Got my Asus Prime B350M-A mATX installed with 1800X at stock speeds - overclocking is for another date, I need the PC to be operational before tomorrow and have 800GB of files to copy back onto the 2TB Samsung 960PRO M2 stick and applications to get working.

Some things I noticed are
a) its an F1 stepping (the one they were demo'ing a few weeks back) - not the rumoured F4 retail version (I notice scramz is the same).
b) the Asus BIOS (I updated it from the installed 405 version to 504) supports my 4 sticks of Corsair DDR4 2666 and reads the XMP profiles (as D.O.C.P.) without problems - so thats 4 x 8GB @ 2666MHz on a "low end" board.

Thanks for the info and impressed the memory worked with no hick ups for 4 sticks

So what is the ram ? Modal opps see the sig impressed that it worked fine great news

I think it's a more useful test to force a cpu bottleneck to actually show where the shortfall is. But people mustn't get carried away with the result. It's good to have more information to alow people to make informed choices. If you're building a machine just for gaming the 1800x isn't a great option. The 1700 and 1700x are better bang for buck for gaming and the 7600k and 7700k are the best pure gaming cpus. If you're doing more than gaming it's a different story. People seem way to interested in scoring points or winning arguments. Or proving that their choice is the best. What we have now is real choice, which means what's right for one person isn't necessarily right for someone else. Masking the differences to show one in a better light doesn't help anyone. Nor does writing one side off because it's a few % down in a synthetic test, which is what 720p gaming is.

CPUz Benchmarking Single Thread

i7 6700K @ 4.0Ghz = 2144
i7 7700K @ 4.2Ghz = 2301

My 1700 @ 3.8Ghz = 2122
My 1700 @ 3.9Ghz = 2216

According the this, my Ryzen IPC is faster than Kaby using less power..... Am I missing something here?

My results seem more impressive than reviewers...

Just to note, I am on a B350 MSI Toma, with bios V1.0, no updated bios yet, RAM at 2400Mhz.

Just need correct drives to allow this performance to apply to gaming.

 

[Scramz]

I am no longer with my PC I will push on tomorrow morning. Seriously am I messing something up or is the IPC higher?

Interesting comments a few pages back discussing the perceived smoothness of the Ryzen in the side by side gaming comparison against the Intel. I personally can't see it that easily and note that they both stutter from time to time.
I was thinking back to the days when AMD brought out the Athlon. Do you remember? Intel went from 2.0ghz up to 3.4ghz with their pentiums, but they were starting to get toasty. AMD came in with the Athlon 64 cpus which used an integrated on cpu memory controller. People tended to find that a lesser clocked AMD socket 939 system was just a nicer overall gaming experience, i.e. smooth and consistent.

Could there be something similar going on here with other architecture differences or is it simply the increased cores/threads available?

As far as I am aware, CPU-Z isn't a particularly accurate benchmark. I believe the R7's benefit a lot from the bigger L2 cache as well. When you get a chance you should try some other benchmarking programs!

That's great 100 points per 100mhz almost.
4.1ghz here 2411 st
https://www.guru3d.com/articles_pages/amd_ryzen_7_1800x_processor_review,23.html

What voltage and temps at 3.8 and 3.9?

I did a dirt 1.35v for both, haven't dropped the volts to find a sweet spot.

3.7Ghz is sub 1.16v, not dropped the volts yet on that either.


EDIT: Wow, I see people at 4Ghz with 1.5 volts, hopefully I can hit 4Ghz at sub 1.38, that be a touch.

EDIT 2: 1.35v 60c on load air cooled.

I'm starting to wonder if it's my ram as I have vengeance LPX2400 but the 2400 isn't on the Qualified vendors list

Thanks man, brilliant real info.You might have a good one give it a go, It'd be great to see refined voltages and see how efficient these bad boys are.
I can't wait fof the r5 or evem the r3.

i think thats possible why not
i saw way more stutter on the 4core cpu video, but the cpu wasnt even hitting 100% on any of its cores so why is it stuttering...
