In an interview, Dr. Lisa Su, CEO of AMD, confirmed that the AM5 platform plans to give as few problems as possible to those who use the AM4 platform, including heatsinks. When intel Alder Lake came out, users who wanted to keep their cooling settings had to adapt it to the new CPU due to the change in size and socket. The AM4 platform has been around for a few years, but has seen a few iterations that brought support for faster memory or new PCI-Express standards.
The future of the AM5 platform is uncertain, but the team behind the success of Ryzen CPUs has taken note. Among their statements, they confirmed that there will be no change in size or shape of the new AM5 CPUs compared to those for AM4, meaning users can keep their current coolers without worrying about the new socket size.
You will not have to buy new heatsinks or adapt them for AM5
In an interview with Robert Hallock, Director of Technical Marketing, and Frank Azor, Chief Architect of Gaming Solutions, they were asked about the design of the AMD AM5 platform . Among the questions was why AMD switched to LGA instead of making another PGA processor. Hallock responded that this decision was based solely on the pin density required for connectivity and next-generation interfaces like PCIe Gen5 or DDR5. Since the AM5 platform needs more connections to the CPU, pin-based PGA CPUs simply weren't suited for this task.
The design of AMD 's integrated heatsink (IHS) for Zen 4 , debuting with the Ryzen 7000 series, wasn't chosen for its aesthetics, but rather to accommodate capacitors that would otherwise have to be installed on the other side of the processor. Making them the same size as the IHS allowed AMD to fit more heatsink pads on the underside of the processor, thus maintaining the same package size as processors on the AM4 platform.
With this in mind, Hallock confirmed that heatsinks that work on AM4 CPUs will be compatible with future AM5 CPUs. This is in the absence of knowing details such as thermal density or power requirements. Some heatsinks may have minor issues, but in general, they should all be compatible.
