There is a single 14nm I/O die, with eight memory controllers, with Infinity Fabric ports and PCIexpress lanes, and then 7nm chipset which handle the CPU tasks themselves. The EPYC Rome chip will feature eight CPU chiplets giving out 64 x86 cores. This offers not only higher IPCs and a significant increase in overall performance, but also improved security features in the recently announced EPYC CPU "Rome".
Beyond that, AMD is already putting the finishing touches on its Zen 3 EPYC processor, which is slated to be manufactured on a 7nm++ process and launched in 2020. AMD showed a pre-production, air-cooled, non-overclocked Rome outperforming a dual-socket Skylake SP with 56 cores and 112 threads in the floating-point intensive C-ray benchmark. With a focus on Epyc chips for servers, AMD now hopes to surpass the performance of its competitor Intel rather than just match it.
AMD's chief technology officer, Mark Papermaster, spoke in more detail about the 7nm Zen 2 core and the firm's partnership with TMSC, which will be manufacturing it.
What's not known is how much of the Rome DNA will make it into the consumer Ryzen 2 due early next year. Performance gains in terms of instructions per clock will be improved as well. The chips will be manufactured by TSMC on its leading 7nm node, which the company says will give it a significant advantage over Intel, which is now struggling with its own 10nm process.More news: Democrats snatch first House seats from Republicans in US midterms

"It's hard to say on notebooks right now and I need a bit more information on how AMD would implement this in mobile platforms", he said.
The roadmap for Zen began with the first design in 2016. If the claims hold up, the second-generation processor has a shot at being the highest performing datacenter CPU in 2019.
Rome is currently sampling with customers now in preparation for the processors to debut in 2019.
At the special AMD "The Next Horizon" event, AMD has confirmed its total commitment to the datacenter market, unveiling both the new 7nm Vega-based Instinct MI60 as well as showing some of the first details and performance figures for the upcoming 7nm EPYC "Rome" datacenter CPU.
AMD's multiyear investments in data center hardware and software are behind growing adoption of the company's CPUs and GPUs, said Lisa Su, AMD's president and CEO.
