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

[humbug]

So it does seem those frequencies are the base clockspeeds??

Edit!!

Lets hope IPC is indeed close enough to BW-E!!

Yes, in this case on the 1700 its 3.7Ghz and then boosting to whatever TDP / Temps will let it...

Awesome!

I think in another slide the 1800X was 4.2Ghz, so Min 4.2Ghz and boost to ++++++++

AMD's TDP is half that of Intel's though and with higher clock speeds?!

I bet they have a TDP limit which will throttle it down below the base speed when running extreme loads (ie. Prime95), the lighter the load you run the higher it will boost which will skew a lot of benchmarks (particularly games) in AMD's favour. Sneaky.

Not necessarily, it may mean, it will definitely boost to 3.7Ghz at times, but it could boost higher cooling dependent. It could also mean base clock frequency and boost is basically completely undetermined.

AMD having the clock speed adjust to the level of cooling is interesting. Splashing out on high end water cooling might start to make sense again.

All this looks very good and promising, if it turns out as good as it looks other things might start ryzen

I believe that the stated boost clock is a guaranteed overclock, while XFR is like with Nvidia's boost, it is not a guaranteed overclock and will be dependant on chip quality and cooling.

I was just about to buy a new PC on Monday with an Intel i7 6900k but after seeing that Ryzen is going to be released on the 3rd of March and that it compete with or beat the i7 6900k I think I'm going to wait. Plus it is meant to be a hell of a lot cheaper so I could save myself shed loads of money as well which I can spend on other things.

Very excited to see the benchmarks and the reviews. Now I just need to hold off for a month before buying my computer which will be hard as I've been wanting a new computer for a year now.

Yeah, because in super heavy AVX loads Intel don't downclock the chip because their TDP doesn't come close to covering max speeds with AVX 512... oh wait....

Nvidia GPU's do this, they boost the proverbials off for a short duration to knock out a good bench result and then settle 100Mhz less once fully warmed up.

Stress testing they hit a TDP limit and down clock never passing it.

Yes i think AMD's CPU's will behave in the same way, but they are not the first to do it.

I dont think so. I think its base clock. Because the Boost is dependant on cooling capability so it will fluctuate. From what ive seen the boost clocks are not confirmed only base clock speeds/frequency. Its like when they announced Zen and said 3.4+ frequency.

for example

Guaranteed Frequency 3.7Ghz
Boost Frequency Unlimited ( Cooling Dependent )

so to me that says the base speed should be 3.7 because that speed is guarenteed. Means what ever workload it will run at 3.7.

It will boost above this depending on your coolers capability on keeping temps low.

I believe stated boost is a guaranteed overclocks, similar to Nvidia GPU's, while XFR overclocking beyond stated boost is silicon and cooling dependant and not guaranteed.

Agreed it's just AVFS but with an additional P-state that uses data from the loop feedback from the power, voltage, temp sensors etc, to apply additional clock frequency beyond the turbo boost (a pre-determined boost p-state).

 

[humbug]

I would not be surprised if AMD send the best binned RyZen Chip's to reviewers, with AIO coolers.
The combination of very well binned chips, the unlimited boost tech and the AIO cooler has them running at silly Mhz during testing, even in low threaded benchmarks those RyZen chips knock out very good results.

So as I haven't owned an AMD based computer since about 2006 what are the good AMD motherboard manufactures who are likely going to make the best AM4 ultra high end overclocking motherboards? I currently have an Asus Sabertooth X79 motherboard which I like so I'd like something that is just as high end for Ryzen.

I know we don't have any information on releases yet but you should be able to tell based on models already released.

It might explain why AMD has made such a decent stock cooler in the Wraith cooler. Reviews seem to indicate it is more like a £20 to £30 stock cooler IIRC.

MSI and Asrock tend to make very good motherboards.

I think it will probably be all chips will do 3.7Ghz with sub 95 watts of cooling. Turbo clockspeed isn't an overclock.

Ah, cool. Thanks . I'll keep an eye on them when the new motherboards are released.

I think the same principles apply for AMD motherboard's as Intel, they have in the past been very similar, just with different sockets and chipsets.

My last AMD board was and Asus Sabertooth 990FX https://www.asus.com/Motherboards/SABERTOOTH_990FX/

It was excellent, it ran an FX-9590 (a ridiculously power greedy CPU) @ 5Ghz permanent. probably the only board from that era which could do that, i think it was pulling near 300 watts.
