AMD Zen 4 in the Ryzen 7000: From autumn with 5 nm, 5 GHz, DDR5 & PCIe 5 on AM5 boards

The time has come in the second half of 2022: AMD will replace the AM4 processor socket after a service life of 4.5 years. The new AMD Ryzen generation with Zen 4 cores takes its place in the AM5 socket alias LGA1718 and requires new mainboards. Because the Zen 4 cores will not only use faster DDR5 RAM, the processors should also be able to consume more power – the talk is of up to 170 watts. In addition, Zen 4 aka Ryzen 7000 will also bring PCI-Express 5.0.

As usual, AMD has the new processors manufactured by the Taiwanese chip manufacturer TSMC and uses 5 nanometer technology (TSMC N5) for this.

With the Ryzen 7000 processors, AMD wants to provide the fastest gaming platform again. Intel’s Core i9-12900K and AMD’s Ryzen 5000 with 3D-V-Cache are likely to be arguing for this title in the meantime. By the end of 2022, AMD will have to compete against Intel’s Core i-13000 CPUs with Raptor Lake architecture.

At the CES trade fair, AMD showed a game sequence from the shooter Halo Infinite on a demo system. The cores used by the game ran with a clock frequency of more than 5 GHz. Whether the turbo clock will be that high for all cores depends on their load. With a higher TDP and 5 nanometer technology, there would be a certain amount of room for improvement.

As the rumor mill already knew in July 2021, AMD will shorten the legs of the CPU with the AM5 version. The new version uses a Land Grid Array (LGA). The springs for contact with the CPU are located in the mainboard – the processors have flat contact surfaces. So CPU legs can no longer bend, motherboards are more sensitive. A metal frame with locking device presses the CPUs into the LGA sockets to ensure perfect contact.

Intel has been using this principle for more than 15 years. AMD has also been using LGA sockets for years, but so far only for processors for servers and workstations, most recently the LGA4096 for Epyc 7001, 7002 and 7003 and their workstation offshoots Ryzen Threadripper (Pro).
