Of course, but you said Intel was following AMD example, when in reality Intel had it first.

And this very far down the line, in the past.
Interesting to see that the CPUs will not be 125W, but 95W only, with Haswell/Broadwell level of performance. And those are the CPUs that can go into the iMac, rather than Mac Pro.

More yawn from the AMD PR department.
Seriously, don't post this stuff until ATI actually starts shipping product. ATI have over-promised and under-delivered so often that just ignoring the PR releases is the best tactic.
If you will ignore the hype that was created on forums, and read what AMD actually promised was 100% in line with real world. Biggest fail was Bulldozer, however when they later touted increases in performance and efficiency of their chips, they were right, and what they promised was shown in real world.
I understand that you could've not had been following past years of AMD CPU history(me neither!). But I researched lately... They should get at least a leap of faith 😉.
So the best AMD can offer is performance 2/3 generations behind Intel with worse efficiency? Intel's consumer CPUs top out at roughly 90 W and desktop Kaby Lake will be shipping by then. AMD seems to be banking on the more slower cores approach which is going to be a tough sell. The majority of consumers seem just fine with fast dual cores.
I am willing to give AMD a chance, but my expectations are low. I like to think about what form factors Apple could come up with an AMD APU that combines Zen/Vega but if you asked me right now to build my dream xmac/mac pro it would be the fastest quad core Kaby Lake chip plus a Nvidia Titan Pascal.
Wait what? Do you even read? 8 core CPU, with clock for clock performance of Haswell/Broadwell CPUs, in 95W TDP compared to 140W thermal envelope is worse efficiency?
The CPUs in question were HEDT parts. Those are costing over 1000$. The 95W CPU from AMD still can be HEDT, and have correct pricing for this segment, however it will not have worse efficiency.

Read what? Vaporware rumours?
We all saw the hype for Bulldozer before it shipped, and the embarrassment that it was when it eventually shipped.
Come back when we can go to http://ark.amd.com and see specs for shipping products.
Until we see independent reviews of production Zen systems, forgive us if we wonder if Zen will be "Bulldozer II".

You want to know why I have now more confidence in Zen?
I will turn back to one particular thing: http://www.anandtech.com/show/10591...t-2-extracting-instructionlevel-parallelism/7
Look at the caches and resources. They are on exactly the same level as Broadwell architecture as it goes for feeding up the CPU cores.
In other words. There are only two things that can let down this microarchitecture. Caches bandwidth, and core clocks. If they will be within 3-3.5 GHz ranges, everything will be fine. We will get Haswell-E Performance in 95W thermal envelope. If the CPU design on revision A1/A2 will be 125W, we can expect BASE core clocks within 3.5-3.7 GHz. So the only thing that can ultimately right now let down the CPU are the caches bandwidth. And this only remains to be confirmed.
However there is one thing that can hint that caches are actually very competitive in design. Blender test where core for clock comparison with Broadwell-E CPU vs Zen, the Zen CPU was 2% faster in execution.
This is not vaporware. This is all we know from CPU microarchitecture analysis, and from hints from industry.
Well after all this I have thought about another thing that can destroy Zen. Pricing. It will be very competitive, however I would not expect extreme value. 8 core CPU will most likely be priced in 700$ range for HEDT market.

This is the same discredited tactic of micro-analyzing architecture details that you've used for GPUs - only to find that the shipping product falls far short of your mathematical models.
That's why I said that I'd wait for independent, real world benchmarks on production systems. I don't care if it has an eight speed automatic transmission, dual turbos and quad exhausts - let me hear from some who's taken it for a test drive.

Nobody knows what it is.
However as a point of view, there are two Intel 8 and 10 Core CPUs.
Haswell-E 5960X - 91 s.
Broadwell-E 6950X - 84 s.
The score can still be for 16 core 2.3 GHz version of AMD Zen CPU.
Yup, it looks like it is 16 core version of the CPU.
http://ark.intel.com/products/81057/Intel-Xeon-Processor-E5-2695-v3-35M-Cache-2_30-GHz this CPU scored 58 s. in the benchmark.

So why'd you waste our time with a link that shows it getting smacked by a Xeon E5 v2 ?

The Zen section of this graph is practically magic.
You know, like stereo speakers on the iP7.
If only AMD's product was as fast as their roadmaps we'd all have flying cars.

The graph baseline is not 0.
Lol... That's an appeal to authority and a logical fallacy... As you say, he's a journalist, not an AMD representative or engineer. So whatever he says is still just a forum post and his opinion until official announcement are made.
Doesn't mean he can't be wrong now. I get it that you are a big fan of all thing AMD to the point that you keep posting every single bit of forum posts, blogs and innuendos that you find on the internet. But in the end, only actual existing hardware available matters, all the rest is just so much marketing background noise of no value whatsoever.
Want to know why I take it as a confirmation? Because I have had information about Black Edition Zen CPU months before, which I have touted already: https://forums.macrumors.com/threads/amd-zen.1988652/page-2#post-23267544
