AMD 7nm Based Zen 2 CPU Architecture Features 13% IPC Improvement, Alleges Rumor – 7nm Process To Deliver Higher Clock Speeds

Oct 17, 2018

AMD Zen 2 architecture based processors will be featuring a good performance uplift over their predecessors. This performance boost would come directly from incremental IPC gains which are expected in the upcoming generation of Ryzen, Ryzen Threadripper, and EPYC CPUs. The latest rumor details a bit about the IPC advancements we would be looking at when Zen 2 arrives in the market.

AMD Zen 2 CPU Architecture To Deliver An Average 13% IPC Improvement Over Zen+, Rumor Alleges

The rumor comes from Bits and Chips through their official Twitter feed where it’s alleged that the Zen 2 architecture brings an average of 13% IPC (Instructions Per Clock Cycle) uplift over the Zen+ architecture. It is stated that this performance uplift is specifically in scientific tasks so maybe the numbers are from early EPYC 7nm ‘Rome’ samples which should be out in the wild. There are no gaming performance results available at the moment since the consumer samples are still away from launch.

It is stated that the CPU IPC improvement was noted at the same clock speeds as previous gen processors. No other details are mentioned but if true, we can be looking at one of the biggest IPC leaps in the CPU department since a while. Intel, for now, has been stagnant in the IPC department while AMD’s Zen to Zen+ jump yielded a 3% IPC lift. This double-digit IPC gain has not long been seen in the CPU department and it’s a welcome one as it would prompt competition to up their game in IPC gains again which would result in better products for consumers.

Also, this isn’t the first time we are hearing about double-digit gains from the upcoming Zen 2 CPU architecture as it was also detailed in an earlier rumor that the new processors would yield a 10 to 15% IPC gain.

We know that aside from their server aimed EPYC ‘Rome’ lineup, AMD is also working on their new 7nm, Zen 2 based Ryzen parts. Earlier, rumors have stated that these CPUs are already working in AMD labs at speeds of up to 4.5 GHz on an 8 core, 16 thread SKU. If AMD manages to extend their product lineup with faster and much more affordable 7nm CPUs in the coming year, the can gain a significant chunk in the CPU market share with ease.

A 10-15% IPC improvement can yield some good results considering we are also expecting to see some clock rate bumps in the next-generation processors too. That coupled with architectural changes and higher memory frequency support will end up delivering much better performance than current CPUs.

Of course, these are all just rumors but they are still interesting for users who are looking forward to the next-generation AMD Ryzen CPUs. Expect more details in the coming months when AMD is ready to unveil their next-gen CPU design to the public. AMD has promised to talk about their 7nm CPUs and GPUs at CES 2019 so expect more details during the event.

Are you planning to upgrade to a next-generation Ryzen (mainstream cpu) when it arrives to market?
