AMD 12nm Ryzen launches in April
AMD has confirmed in official press slides that second-generation Ryzen high-performance CPU will launch in April 2018. AMD promises that first 12nm Zen+ processors will have higher clocks and support Precision Boost 2 technology.
Additionally, AMD has confirmed that X470, second-generation chipset for Ryzen CPUs will also launch in April 2018. According to AMD, X470 platform is to be optimized for 2nd Generation Ryzen CPUs.

The official roadmap confirms that while Ryzen 2nd Gen will launch in Q2 2018, the enthusiast desktop Ryzen Threadripper series will be released in the second half of 2018, along with 2nd Gen Ryzen PRO series.

During AMD’s CES 2018 Tech Day, CEO Lisa Su announced the plans for the second-generation Ryzen processor roll-out in April. This is the revised design that has been rumored for months, with a process technology change and slight tweaks to features.

Details are expectantly short, but what we know is that these parts will move from a 14nm process technology to 12nm from GlobalFoundries. AMD is calling the design “Zen+” and this is NOT Zen 2 – that is coming next year. You should expect higher clocks for Ryzen 2000-series processors and improvements to Precision Boost that will enable more consistent and gradual clock speed shifts in workloads of interesting like gaming.

Also on the roadmap now are updated Threadripper processors with the same “Zen+” enhancements, coming out in 2H of 2018.

The great news for enthusiasts that have already bought into AMD’s current generation platform is existing motherboards will support this processor update, as long as you have the associated BIOS. Motherboards are already being updated today for the channel (to support the Ryzen APU launch) so there should be little concern with compatibility come April.

However, there IS a new chipset coming with “Zen+”, the AMD X470. Information on it is also slim, but it includes some optimizations and fixes. AMD had growing pains with the initial set of motherboard releases including power concerns and routing issues, both of which are addressed with the new design.
That’s all we know for now, but I am excited to get my hands on the Ryzen second-generation processors this spring to see how much performance and behavior has changed. Intel has definitely changed the landscape since Ryzen’s first release in March of 2017, so enthusiasts should welcome the back and forth competition cycle once again.
