I know who Francois Piednoel is, lol. He "rants" on all kinds of subjects, some unrelated to x86. He just doesn't think there is enough proof yet to prove the performance of Zen, but yeah I would imagine they are a bit worried about the competition as well.About half his post,is the Intel principle engineer badmouthing a competing product. He seems spooked for some reason,to go on such a massive rant on Twitter. If you look at the scores for the FX8350 in Blender,Intel CPUs absolutely destroy it.
If the AMD chip is as bad as he thinks it is,he would have no need to actually rant like that,since the benchmarks at launch would tell the full story. You never saw a similar rant like that before Bulldozer was launched,right??
You know there is relatively easy way to check his theory. His theory if I understand him correctly is that Ryzen could have a poor branch predictor, and because Blender is not very branch predict difficult workload it's looking better than it normally is.
Yea despite having something solid, winning the partners and their product/execution is key for sure. All the DT, Mobile and Server market rests on them.They'll most likely under price it just to attract people like me who have felt burned by AMD's chips lately.
I'm still concerned about their partners motherboard quality, hopefully Ryzen has some serious quality behind it.

We have the benchmark, we can check and see how Bulldozer or a BD derived chip does in it. From my recollection people have posted FX results and they weren't anything to write home about. And we know BD cips have a long pipeline and not so great branch predictor. So this should be one of BD's best benchmarks.
I don't understand his point about the game loading. Rene was waiting on a game countdown to join a game, the wait wasn't CPU load based. Also would a ray tracer really not be branch prediction dependent? I would imagine ray tracer by it's pure nature has a lot of variables and different branches to take as it passes through different materials and different reflections it has to calculate.
This is why I think he's completely off base.AMD used Blender for a very good reason - the FX8350 absolutely sucks in it compared to Intel,and this is why he is talking like that. Whether or not AMD has better SMT,lower IPC,etc the fact is AMD has managed to catch up in that benchmark,with a huge per core/per thread improvement in performance.

Running CodeAnalyzer on a preZen AMD chip would reveal the required details, and just where the older chips struggled in this benchmark.This is why I think he's completely off base.

The Intel guy, I don't agree with as I stated (he had some AMD gurus replying to him!).
If you read, I debunked his fear mongering so that it couldn't be used as a source.

It will be interesting to see. But I did not quite expect Ryzen to have a 19 stage pipeline. I am quite confident on the clocks of this thing now. Just based on what we know about Excavator pipeline on 28nm planar and the fmax it could reach there. I think just shrinking Excavator to 14nm FF would yield a 25% clock boost, based on what we've seen from GCN. And Ryzen with its long pipeline could reach those high clocks as well. If they really got a great branch predictor in it, this is going to be one helluva competitive chip. Very excited to see the final benchmarks with Boost in the play.
Maybe we now know a reason for the Skylake/Kaby Lake respin.

Aye, Lisa spent quite the moment there to praise it. She even went as far to say that it's responsible for 1/4th of the IPC gain we're seeing. Now it is a CEO praising its own product which is to be taken with a grain of salt, but she really doesn't strike me as a CEO who overhypes things, at least she's much better than the AMD's past leadership.A point of interest is that the branch predictor seems to have some capacity for learning - hence it should do better with frequently used programs. This should be especially true for design professionals who rely mainly on a small set of development tools. Oh, and servers, which often run just one main application (at least in large data centers).
some guys live in the dream?
I wont buy their product with high price. no way.
a company with fail product? A company is gone but the earth is still turning.
this is the reason:
1. for now all of benchmark, I still thinking Intel better(if drop the pirce should be nice)
2.BMW vs Ford, anyone agree if Ford have high price than BMW? Brand value different.
if any company just push garbage few years and asking customer pay for it. did you accept?
you guys really crazy fans, I was an AMD fans with lot of AMD CPU.
now...go hell...the damn price with mouthful of lies.
I just bought RX 480 with fully regret, bye bye Vega no more again.
Terrible Watt kill the polar bear and pls follow PCI-SIG.
you cant design something without criterion.
the only good is the driver, no more crap CCC no more blue screen, nothing more.
pascal driver really shit this year.

http://www.theregister.co.uk/2016/08/22/samsung_m1_core/It is interesting that Samsung has broken ranks by publicly declaring that its prediction engine is a neural network. David Kanter, Linley Group's microprocessor analyst, told us today's state-of-the-art branch prediction systems are based on neural-network-like designs: for example, AMD's Jaguar and Bobcat predictors use similar technology. Burgess, now a veep at Samsung, was formerly chief architect of AMD's Bobcat microarchitecture.
AMD's Zen architect Mike Clark confirmed to us his microarchitecture uses a hashed perceptron system in its branch prediction. "Maybe I should have called it a neural net," he added.

In the server market, yes. They simply couldn't make enough to reach 50+% overall. That shouldn't be a problem this time, so long as the demand is there.
AMD stock price will allow them to get more in loans. AMD has cut huge amounts of their debt, and are prime for investment. AMD could very easily offset a reduction in margins and use the investments to supplement things like R&D. AMD could likely sell Zen for $600-$700 at the top end and still make very good margins. If AMD can gain enough market share, then they can leverage that for further investment to supplement cash.
You are thinking in small business terms, and not in corporate terms. If AMD goes after the cash pop, then that means higher prices. Higher prices directly reduce consumption at the higher price point vs a lower price point. That limits market capture which allows Intel to come back if they so choose.
What is important for AMD is to gain market share and lock people into their system. If AMD can get a win in the server market and the next gen is equal or slightly behind Intel, that is a win. That is because the cost of moving platforms is expensive and is only worth while if the cost of moving is worth the benefit. If Intel comes out with its next gen and its only a few % faster than AMDs next gen, then many still upgrade to AMD because that means less hardware to buy. Big companies may have the capital to move, but many will not.
Sorry mate. 'Code Analyst' is correct.Ehm, this thing right? http://www.codeanalyzer.teel.ws/
