AMD will be introducing their next-generation Zen 2 based processors next year which will first be featured on the EPYC Rome processors. These will be the first high-performance CPUs to feature a 7nm process node and while they are expected to deliver great improvements in performance and efficiency, AMD themselves have already started giving us hints about what the CPU architecture that comes after Zen 2 may look like.

AMD Zen 3 Will Use The 7nm+ EUV Process Node, Primarily Going To Leverage Power Efficiency With Modest Performance Uplift

It's no doubt that AMD will have the first GPUs and CPUs utilizing the TSMC 7nm process node. Their Vega 20 "Instinct MI60" graphics accelerator is shipping later this year while EPYC Rome processors for the server market would be introduced next year. Now we got to heara lot of architectural details from AMD regarding their Zen 2 architecture and the EPYC Rome CPUs that can be seen here. Zen 2 is currently looking to be one of the biggest CPU performance and CPU efficiency since Zen itself back in 2017.

After Zen was introduced to the market, a year later we got Zen+. A slightly efficient and optimized Zen architecture which was based on the 12nm process node instead of the 14nm process which Zen originally utilized. AMD's latest roadmap now confirms that after Zen 2, we would get Zen 3, Zen 4 and even, Zen 5.

Details for Zen 2 are available but AMD's CTO, Mark Papermaster, has unveiled what to expect from the Zen 3 CPU architecture. First and foremost, AMD states that their claimed performance and efficiency numbers are for a real product while TSMC uses their own methods. Hence, the difference between the power draw and performance uplift estimates from both companies. A node and an actual product are two varying things and you can't compare them both.
