PayPalAMD have released more information about Zen, but the official name is now AMD 'Ryzen' (pronounced as Rye-zen). Their livestream event just finished, so here's a quick overview for you.
They announced that Ryzen 'Summit Ridge' will be on their AM4 platform, which will support DDR4 memory, USB 3.1 v2, NVMe storage and PCIe v3. It will have 8 cores, 16 threads with a base clock of at least 3.4 GHz+ (they may tweak that higher at release). It will boost higher, but they haven't said how high. This is wrapped up in a neat 95W TDP package, so that's not bad at all for what it does.
It's worth noting, that this is their high-end, so their lower end which hasn't really been talked about will differ.
They will come with 'SenseMI', which includes a bunch of thermal and voltage sensors. With this feature, it will apparently be able to adapt the performance based on heat conditions at lower voltages, so if you have a really good cooler for example it can maximise the performance for you. This also includes a smart prefetch and other goodies to help boost performance.
It will be available sometime in Q1 of 2017 for the desktop chips (Q2 for server chips), but hopefully we will see a more solid date soon.
The AMD CEO claims they have hit their goal of 40% improvement over their last generation's IPC (instructions per cycle). This is a massive improvement, and if really true it will put AMD firmly back on the map for a lot of people.
They did three tests against an Intel 3.2GHz 6900K, where the AMD chip came out just about on top, which is pretty impressive. See the linked video in this tweet:
Using Blender, we put Ryzen up against it's biggest competitor, clock for clock, at #NewHorizon. The results speak from themselves. pic.twitter.com/0glPor1jpf

I still think it will be more interesting to see real-world benchmarks done by others, so we can remove any marketing speak and just see hard numbers. I am excited to see them though, as Ryzen could really be the game-changer we've been needing.
What do you think, sound good to you?

As has been said, I'd like to see 3rd party benchmarks too.
Since AMD is also more OSS friendly than nVidia it might finally be the perfect time to build that full AMD system. :-)

I've always chosen my CPUs based on single core performance.
Even today that is still a good selection for real world performance.
So, I'll keep an eye on this and see how it all works out in practice.
In my case choose new cpu using same parameter
I stay interested in i3 7350K because at stock clock have 20% more speed in single core (geekbench) compared my actual Pentium G3258 @ 4.1Ghz
20% is good but is low, in i3 7350K stay interested in how much is possible OC using air cooling solution without surpass 60 to 65 degrees
But if i3 7350K can OC to 5.0 or 5.2Ghz with 1.3 of vcore (maximum) and without surpass 60 to 65 degrees using air cooling solution will be must have in my case

The FX 8xxx was four cores and eight threads...
And now we have eight cores and sixteen threads with less TDP than the FX8xxx... Good sign! :)
I wonder how many FPU per core we have...
While it should not, it outperforms my former i7-2600k (~ the same release date as the i7-2600k) with nvidia 980 (ye, I upgraded the graphics card in the X51) by .. quite a lot. That surprised me. May be due to it running at 4.4 ghz at a core, not 3.4 as the i7 was.

And another exciting note, my compilation time will decrease lol.
Now this close to release I need to save up money for 2 new 400 or 500 series gpu to replace my 980s.

So... The bulldozer modules are very much alive with another name; instead of modules, now they are called cores...
The FX 8xxx was four cores and eight threads...
And now we have eight cores and sixteen threads with less TDP than the FX8xxx... Good sign! :)
I wonder how many FPU per core we have...
It will have 8 FPUs (1 per core, no modules like Bulldozer), the 16 thread is 8 core and two threads per core, SMT (Simultanius Multi-Threading), like Intel Hyper Threading.
i ran the blender test also
Ryzen had 35 sec
mine:
FX-8320@4,4ghz

Normally you'd find the top stable clocks and volts for the CPU then let it apply those through the typical clock throttling method, having the CPU 'decide' itself on what it can achieve doesn't seem sensible or even stable!

they put countless polygons on a plane just to make it take more time to render?
why not show an impressive demo like try to render some frame of sintel at any resolution?
the other demos where more impressive, the blender demo made blender looks dumb.
So, I jumped ship and now 70% of the PCs at work are running AMD FX processors.
Sure, single core performance is better at a given clock-speed with Intel chips, but AMD makes the best value processors, and for multi-core work, AMD FX are pretty effective.
Hoping AMD get "back on top" with their new Ryzen.
See more from me
