I have been looking for it, I swear I read it but they seem to have edited it there was even an slide differentiating 2 versions of the 7nm but it has disappeared from internet.... hahaSource please?
Edit: I just need a source so I can post elsewhere if needed.

Thank you I couldn't find it I thought I was crazy haha
Lets not go crazy on guessing. It's usually better to temper your expectations, so you can be pleasantly surprised if they are exceeded.Wauw, zen+ or zen2 at 4,7GHz or higher would be very promising indeed.

B2-step seems to focus on Uncore/SoC erratas (PCIe controllers, etc.) . I don't see many fixed bugs within the core.
That is ignorant! AMD had a CPU that ram at 5GHz. They won that fight on speed, but performance was lacking. So your ignorance saying just win on speed shows you shouldn't be present in this conversation.
What they need to do is continue on what they are doing. They are looking at a good IPC jump at 7nm. If that causes their CPU to perform the same as Intel's when it is at 4.0-4.4 when Intel is running at 5GHz, then it says AMD has a better product in some ways. Just because you cannot understand faster does not always mean more performance doesn't mean the market cannot figure that out.

My point is that a lower clock speed can still outperform a higher clock speed on single core if the IPC is higher! Intel at 4GHz was beating AMDs 5GHz chip (prior generations). So you cannot just look at speed for single core performance. So your dismissive nature is undeserved.Pfff. You are boring with your own ignorance.
Have you not noticed how well zen is doing. I am sure AMD is figuring out where the ipc bottlenecks are to get on par with Intels latest and greatest with the coming iterations of zen.
But even when AMD is able to close the gap, they still have a clockspeed deficit when compared to Intel fastest cpu.
Benchmarks and games are still used that like single threaded performance.
And do not forget, because of the differences in the architecture, an optimized program for either one architecture will favor one and be lacking on the other.
That is not going to change.
For me it is already a done deal, i am saving up for a1600x. It will be a lot faster than what i have now.

Meanwhile, what we see with AMD currently is better multithreading scaling, seen where Intel, in certain tasks, needs to run at 400mhz higher than Ryzen to get the same score (BW-E vs Ryzen).
Now, I do agree AMD will get more IPC and speed in the future, but looking at single core speed alone, without more, means nothing.

But you finally said something that fully takes into account both IPC and speed. Shame that now you are talking my language you go away.Well, that is the point zen closed the gap but Intel latest is still faster in IPC, not much but still faster. And besides that, with the current process a 4c/8t zen cannot match an Intel 4c/8t skylake.
And although zen is more efficient now at clocks lower than 3,4GHz because of 14lpp, Intel has a clockspeed advantage because of their own 14nm process.
Intel will reveal tomorrow what they have cooked up.
And that is why zen needs that 7nm process as well. Improved ipc for the next iteration is not going to cut it alone.
Intel is not sitting still either. Right now they will do nothing but provide a new product range and keep faith in their brand name.
8c/16t at clocks much higher than 4GHz at a lower than 95W tdp is going to be the norm for AMD within a year or 2.
I am not going to reply anymore after this post.
If you're referring to post #97, that's what I understood him to mean all along by "...AMD will have to match clock speeds as well".But you finally said something intelligent, taking into account both IPC and speed. Shame that now you are talking my language you go away.
--snip--
I missed the "as well," but it doesn't mean, necessarily, that they must match, rather increase unless IPC goes up significantly.If you're referring to post #97, that's what I understood him to mean all along by "...AMD will have to match clock speeds as well".
Ryzen, Threadripper, Epyc. All the same, just 1, 2, 4 Die/socket. Improvement to one is improvement to all.Anyway, it seems Zeppelin is now at B2 stepping, as the rumor mill had it a few months ago

This should be what's in use for Epyc and TR, maybe the new stepping also finds its way to AM4.
AMD may have. They stockpiled millions of chips, which MB manufacturers were surprised by. An article did state they may have a different stepping for TR and Epyc. I'll look for the article.Ryzen, Threadripper, Epyc. All the same, just 1, 2, 4 Die/socket. Improvement to one is improvement to all.
Unless you're saying that AMD fabbed and stockpiled all the AM4 ryzen die first.

Tbh, I don't think they will. I think B1 will be used and they will use B2 only if inventory is too low. Instead, they'll try to float to the Ryzen refresh on 14nm+, looking at Q1 2018, which I believe the pro series will also be released on. They have the APU coming up and mobile, so I think they took the B1 entire inventory to build up the R7, 5, & 3. Meanwhile, they'll need most of the B2 for Epyc (which uses 4 dies) and TR (2 dies) as they'll need to match up disabled cores and fill out the entire line.I know they make every product line out of the same die. Of course B1 has some issues here and there as they've popped up the past few months (virtualization bug comes to mind among some others)... we've basically been beta testing Zeppelin B1 in AM4 form so far, AMD was aware of the bugs yet decided B1 was good enough for consumer use, leading to AM4 Ryzen release in March... while preparing B2 for TR and Epyc release.
What I meant is, how will AMD bring the new stepping to AM4? Silent introduction leading to stepping lottery? New models or will they reserve these for Pinnacle Ridge next year?
I took that to mean that B2 would be the new and latest stepping for all products going forward, with a stock clearing transition period for the Ryzen line.http://www.tweaktown.com/news/56891/amds-12c-24t-16c-32t-cpus-called-threadripper/index.html
AMD's next-gen ThreadRipper details so far:
Zen HEDT CPU's are called Threadripper!
Each CPU will include 64 PCI-E Lanes!
It includes 4 CCX's. Lower SKU(Probably 12/24) 140W TDP, Higher SKU (Probably 16/32) 180W TDP.
Socket will be an SP3 LGA
Platform's name will probably be X399
Chips will be B2 revisions.
32MB L3 Cache ES's are 3,3 or 3,4GHz base and 3,7GHz Boost
It is aimed for Retail SKU to have 3,6 Base/4GHz Boost
ES's that are in the wild have 2500 CB R15.
Infinity Fabric can have a bandwidth up to 100GB/S
Announcement; COMPUTEX at Taiwan, sales will start after 2-3 weeks following COMPUTEX.

Do companies normally advertise a new stepping, unless a major problem has been resolved?I know they make every product line out of the same die.

It also goes without saying that TR and Epyc will be upgraded to Pinnacle Ridge, too.
I am sure if they need it to be used, but I don't know how much of the initial line has been sold, especially with the MB shortage and enthusiasts finding out about TR and changes to the X299 lineup. So you may be right.I took that to mean that B2 would be the new and latest stepping for all products going forward, with a stock clearing transition period for the Ryzen line.

8 core epyc make sense if there is request for it, amd wouldnt base its market strategy on random defective partsMakes sense. That would explain some of the weird SKUs like the 8-core epyc. These are just the defect binned parts from stepping B2. If Ryzen and epic used the same stepping, the bad dies would all go into Ryzen 5 SKUs and there would not be an 8-core epyc sku.
