Future AMD Ryzen processors can display a significant increase in density with TSMC's 5 nm process node compared to future Ryzen 3000 series chips based on 7 nm. The details of the TSMC 5nm or N5 process node were released last month and give us an idea of what to expect from future generations of Ryzen processors and how they would position themselves against the competition versus to the Intel range.
Future AMD Ryzen processors can increase transistor density by 80% and gain 15% speed with the Bleeding Edge process node at 5 nm
In a report published by PCGamesN, it is stated that if AMD used the last 5 nm node of TSMC, also called N5, the company could expect an increase of 80% in the density of the transistors, 15% of the performances overall and 45% performance reduction. die region with their new generation Ryzen series based on Zen. Here is what TSMC has to say about its 5 nm process node:
N5 entered into the production of risks in the first quarter and we expect that customers will disengage from this quarter and that volume production will increase in the first half of 2020. With a logical density of 1.8X and a speed gain 15% and an ARM A72 core compared to a 7 nanometer system, we believe that our N5 technology is the most competitive in the industry.
With the best density, the best performance, the best power and the best transistor technology, we expect that most of our customers who use today the 7 nanometers adopt the 5 nanometers. With N5, we are expanding our customer product portfolio and expanding our target market. We are therefore confident that 5 nanometers will also be an important and sustainable node for TSMC.

It seems that TSMC has confirmed the volume production of N5-based chips in the first half of 2020, but AMD will not jump so fast. We know that AMD has planned for its Zen 3 processors to be based on TSMC's 7 nm + (EUV) process node. Chips larger than 7 nm will make up the vast majority of TSMC's orders at AMD. The 7nm + process node itself offers a dramatic increase in density (20%) and increases energy efficiency by 10%. The chips based on Zen 3 are planned for 2020 and the launch of Zen 2 this year.
The question is whether Zen 4, currently in development, would use the TSMC process node 5 nm or not. If AMD ends up using the TSMC 5nm node by 2021, they will have a huge advantage over Intel, which will still use its 10nm process node for both server-based and consumer-based processors. However, Zen 4 chips can also use another node that TSMC has planned to launch after N5, this is the N6 or 6nm process node.
Although the logical density is not the same as that of 5 nm (a slight increase of 18%, about the same as 7 nm), the 6 nm process node will offer 100% compatibility with base of 7 nm and 7 nm. So, suppose that AMD wants to save time and deliver better returns for its Zen 4 chips, then N6 is the ideal way to choose.
As we continue to improve our 7-nanometer technology and take advantage of the EUV learning of N7 +, we now introduce the N6 process. N6 has 3 major advantages. First, N6 applies 100% compatible design rules with N7, which allows the customer to migrate directly from the N7-based design, which has significantly shortened the time to market.
Secondly, N6 can offer a higher logical density of 18% compared to N7 and offers the customer a very competitive advantage in terms of performance against costs. Third, N6 will provide shorter cycle time and better fault density. Production at risk of N6 is expected to begin in the first quarter of 2020 and volume production is expected to begin before the end of 2020.

Whether AMD chooses 5nm or 6nm for its Zen 4-based next generation processors, one thing is confirmed is that AMD does not face any imminent danger from their rival Intel who is stuck with his node process to 14nm until 2020 and that will have 10nm to serve. since a long time, after 2020.

The most interesting thing would undoubtedly be the way the new generation chips would be designed by AMD, which has already started the Chiplet revolution that will arrive on its Zen 2 based processors in mid-2019. Chiplet's design paves the way for many interesting applications in Processors, APUs and SOCs are opening up a new era of higher core numbers, increased efficiency and increased performance.
