AMD is getting ready to preview their next-generation hardware tomorrow at the Next Horizon event but while that event would give us a look at what red team has to offer to consumers and corporate sector, we also have some rumors regarding the much awaited Zen 2 architecture as posted by Chiphell forums.
AMD Zen 2 Frequency and IPC Higher Than Expected On Early Engineering Samples, Possible Preview Tomorrow at Next Horizon Event
Tomorrow, AMD is going to talk a lot about their 7nm products which includes both CPUs and GPUs. While GPU talk would be mostly centered around Vega 20 with a possible look at AMD's NAVI GPU which is aimed for launch sometime in 2019, the CPU talk would go around the AMD ZEN 2 CPU architecture. The event will start at 12 AM (Eastern Time) on 6th November, 2018.
AMD's Zen 2 architecture has long been in the works. AMD's design team started working on Zen 2 right after the finished working on the first Zen architecture. We know that refinements were made to the original architecture and we got the new Zen+ design but the majority of the team was then working on completing the design for Zen 2. In February of this year, it was reported that AMD had finished designing the chip architecture and would be available for sampling later this year with a range of products available starting 2019.
In the server market, we will continue to work closely with major cloud vendors and OEMs to ramp their first generation EPYC-based systems while also completing key development milestones on our next generation Zen 2 based server platforms. Our Zen 2 design is now complete and we will be sampling to our customers later this year.
Su at AMD
From the above quote, you can tell that the priority market for Zen 2 as previously disclosed, is the corporate sector. AMD is aiming servers first with Zen 2 and they want to really to push their new chip architecture against Intel's Xeon platform which has been taking a major hit since EPYC made an entrance to the server market. The other products that we will see based around the 7nm Zen 2 architecture would be Ryzen and Ryzen Threadripper CPUs. These are the consumer mainstream and high-performance desktop CPU segments which have also been a tremendous uplift for AMD in recent years.

AMD Zen 2 - More Than Just a Frequency / IPC Bump
Most people think that Zen 2 is nothing more than a generational Frequency / IPC bump. That is a very wrong assumption as Zen 2 as an architecture is entirely overhauled. The jump from Zen to Zen+ was one incremental step, the jump from Zen+ to Zen 2 aims to be a revolutionary step. Yes, the rumors claim that the IPC improvement and higher clock speeds are there. They also mention that those are higher than expected on very early engineering samples. This shows that final retail samples could be more than 15% IPC jump versus what we have been hearing for a while. But it doesn't end here.
Zen 2 is also aiming to fix and improve upon the memory controller by reducing the memory delay and allowing better support for higher frequency, lower latency memory. This is great considering the consumer PCs already have access to fast memory but it is also crucial for the server market, which currently relies on higher bandwidth access directly from the system memory. EPYC 'Napes' disrupted the performance charts with stellar bandwidth increases and reducing delay could get it up to speed with competitive Xeon platforms too.
The other thing being talked about is AVX support. It is said that Zen 2 won't support AVX-512 but will definitely get AVX performance enhancement compared to what Zen 1 can do right now. The clock speeds also get a huge jump, thanks to both, the TSMC 7nm node and revamped architecture design and one can also expect refined boost frequencies, allowing for higher XFR and Precision Boost limits.
It's also said that we might get our first performance or early preview of the Ryzen 3000 series CPUs at tomorrow's event, considering the Ryzen 2000 series has been out for a while and now available at major discounts. The launch for the new Ryzen family would still be aiming an early 2019 release window but getting an early look for the next-gen Ryzen desktop CPU family would really be interesting for all. Once again, these are just rumors but they actually fit in with what we have been hearing, still, make sure you tune in to tomorrow's event. For now, let us know your own thoughts of the 7nm Zen 2 architecture.
