AMD taps into Samsung’s 4nm Node for Zen 5c Dies, revolutionizing Hybrid and Cloud CPUs.


November 24, 2023 by our News Team

AMD has diversified its chip production by tapping into Samsung's 4nm node for its Zen 5c dies, allowing it to optimize its supply chain and meet the demands of various market segments.

  • AMD is diversifying its supply chain and reducing reliance on a single foundry partner.
  • AMD is able to tailor its products to specific requirements and performance targets.
  • AMD is able to secure supply for its server segment.


AMD has made a significant move in its chip manufacturing strategy by tapping into Samsung’s 4nm node capacity for its Zen 5c dies. This marks a departure from AMD’s previous single-Foundry approach, where it primarily relied on TSMC for its chip production. The decision to split its Zen 5c production between TSMC and Samsung is aimed at utilizing the strengths of each foundry.

According to a report from DigiTimes, AMD will use Samsung’s 4nm node for the “basic” variants of the Prometheus (codename for Zen 5c) die. On the other hand, TSMC will continue to manufacture the advanced variant of the Zen 5c die on its 3nm-class process node. This move allows AMD to diversify its supply chain and reduce reliance on a single foundry partner.

While rival nVidia has been following a dual foundry approach for some time, with TSMC being its primary partner, AMD’s decision to tap into Samsung’s 4nm node is a new step for the chipmaker. It shows that AMD is willing to explore different manufacturing options to optimize its chip production.

Typically, chipmakers tend to use the same process technology for a given IP. However, AMD has previously manufactured RDNA 3 GPUs across different process nodes, using 5nm for Navi 31/32 and 6nm for Navi 33. This flexibility in manufacturing processes allows AMD to tailor its products to specific requirements and performance targets.

One reason behind AMD’s decision to utilize Samsung’s 4nm node could be to diversify its supply while still benefiting from performance and efficiency advantages. Apple is currently the only client utilizing TSMC’s 3nm capacity, which is expected to be used for the client-class Zen 5 chips. By tapping into Samsung’s 4nm node, AMD can secure supply for its server segment, which is a lucrative market.

It’s worth noting that Samsung’s 3nm node utilizes Gate All Around (GAA) transistors, an evolution of the FinFET technology used by TSMC’s 3nm nodes. However, the yields of advanced nodes have been lower, leading many fabless chipmakers to prefer TSMC for their manufacturing needs.

Overall, AMD’s decision to tap into Samsung’s 4nm node for its Zen 5c dies represents a significant shift in its chip manufacturing strategy. By diversifying its supply chain and leveraging the strengths of different foundries, AMD aims to optimize its chip production and meet the demands of various market segments. This move positions AMD as a formidable player in the hybrid and cloud CPU space, setting the stage for further innovation and competition in the industry.
