Lisa Su confirms that the Ryzen 7000 will use a high-performance version of TSMC's 5nm

There are several new details surrounding the CPU AMD Ryzen 7000 ‘Raphael’ Zen 4 and the respective AM5 platform that have been revealed this week.

In an interview with the executive director, Dr. Lisa Su, confirmed that the TSMC 5nm process node used by Zen 4 cores is not a common node, but a specially optimized variant that is designed for high-performance computing.

Dr. Su said that their technology roadmaps are all about making the right decisions, explicitly stating that 5nm technology is highly optimized for high-performance computing, not the same as other 5nm technologies that already exist. exist.

TSMC said some time ago that the improved version of its node promises a reduction in power consumption of up to 15%, improving performance by up to 7% compared to 5nm 1st Generation. These are quite noticeable differences when we talk about high-end products, and even more so if we take into account that the original predictions spoke of up to 10% improvement in energy consumption, improving performance by 5%.

The same Zen 4 cores will be used to power a range of AMD chips, including the fourth generation EPYC Genoa and Ryzen 7000 ‘Raphael’ families. For Raphael specifically, we’ll be running at 5GHz speeds. At CES 2022, AMD already showed off a Ryzen 7000 CPU running Halo Infinite clocked at 5GHz across all cores. 5 GHz on all cores means that with a single core it will be above 5 GHz, which means that Zen 4 would be the first AMD architecture and CPU to officially break the 5 GHz barrier.
