AMD Ryzen 7 CPUs Shipping 2 March, Pre-Order Today

Wrong. All Ryzen 7 have XFR.

Even AMD website said no XFR for R7 1700.

Expecting XFR to impact Michael's benchmarks is however pointless, imho. I don't expect him to benchmark with liquid cooling.

XFR is a pointless technology ? Can you show us some benchmark please

You do realize right that AMD has lied all these years and -all- the 8 "core" products launched to date are actually quad cores? It definitely is true whether AMD admits it or not.

CMT vs. SMT, the differences are well known. CMT does not fit the traditional definition of a core. It's much more than simple hyperthreading, but it isn't two full independent cores either. Calling it a "lie" is fanboyish. Calling it a bad design with underwhelming performance is more accurate. Thankfully we can put all of that behind us with the release of Zen.

way too many of these boards use Realtek ethernet, even from manufacturers that have recently used Intel ethernet :/

Yet on the tech day they told explicitly that X does *not* stand for XFR and *all Ryzen 7* are going to have it enabled.

I'm not saying it is a pointless technology. I'm saying in the current configuration it won't have much of an impact with additional 50-100 MHz.
I think they expected lower clocks in general earlier in development. Now they can go up to 4 GHz with sane voltages and power consumption. And the chip has some barrier from which you can't raise the clocks anymore, even if you add a ridiculous amount of voltage.
XFR might become more important for improved fabrication, improved Zen cores or port to 14 nm SOI.

Besides, XFR is not entirely new. Carrizo/BR have AVFS etc. It is just few more boost steps above the "max boost". And yeah, if you are overclocking, it is not significant at all.

If we stright follow AMD site, it also says that there is no coolers which comes with 1800X and 1700X, only 1700 comes with a cooler

http://www.amd.com/en-us/press-relea...2017feb22.aspx

On other places we see some models comes with a cooler and some not



Basically that XFR (Extended Frequency Range) all depends how good your termals are under full load, which require probably liquid cooling for the best results... that is a point some people think it (might be) pointless.

These might not be even interested in overclocking so much also, so "it easier to just grab 1700" logic comes to mind

[juno]

you are completely wrong the BASE clock of a 1700X is 3,4ghz the BASE clock+XFR is 3,9GHZ

Base clock is 3.4, boost clock is 3.8, so xfr brings an additional 100 MHz.

Clocks for multi core boost are still TBC.

[dungeon]

but the HOLE POINT OF XFR is Liquid cooling or even better compressed-gas refrigerator cooling

And you expect Michael to also buy and play with liquid or gas coolers to test how much this could be pushed?

Where in reality and oficially only 1700 comes with cooler, Spire. Other than that, on other Ryzen models people might expect to see Max or Stealth or nothing

That's total bullshit. What you just said is fanboyism. No other x86 architecture scales per thread like AMD's CMT architectures. It definitely beyond any doubt has the highest performance potential compared to any other x86 design. By at least 50% and that's huge. The fact that AMD didn't scale it is what the problem was and not the architecture. It was and still is bad ass.

If AMD scaled up a modern CMT architecture to 8 actual cores with 3 integer units per pipeline it demolish ZEN.

[dungeon]

yes i expect michael to benchmark XFR technology on different coolers like AIR vs liquid vs GAS

Do you expect Michael to break world record on Linux also?

I think most people are interested to see how stock behave, playing further around depends on knowledge but also third party solutions (better mobo, better cooling) and of course luck... especially on Linux we need luck

[edwaleni]

Did you just come here from the past in a time capsule? Single thread performance is totally irrelevant AND has not been scaling for years. Besides most apps are already utilizing 4+ cores and/or GPU acceleration.

There are still apps in the world that are thread performance sensitive. Perhaps not in desktop, but they do exist. When the Opteron version of Ryzen sprouts we will put it in our lab to check it out. We have many thread sensitive apps still on Sandy & Ivy Bridge. With 4 year life cycles of server hardware, this version from AMD will be a little late but the cost may be enough to wait for.
