AMD unveils 5nm Ryzen 7000 with Zen 4 cores • The Register

AMD has revealed more details of its Zen 4 processor architecture, a desktop CPU that makes it work, and a socket for this product.

The CPUs will be called RYZEN 7000 and will feature the Zen 4 architecture, based on a 5nm process from TSMC, according to AMD CEO Lisa Su, doubling the cache per core to 1MB, containing instructions tailored to the needs of Applications are tuned with artificial intelligence and a clock offers speeds that can exceed 5 GHz.

Zen 4 chiplets will sit in a chip based on a 6nm process that integrates RDNA 2 graphics, plus silicon needed to house DDR5 memory and drive PCIe 5.0 controllers.

The CPUs will find a home in the AM5 socket – AMD’s first new CPU package since 2017’s AM4. AM5 uses LGA (Land Grid Array) technology and has 1,718 pins. Motherboards using the kit offer up to 24 PCIe lanes and 14 USB interfaces – some at 20 GB/s and all capable of handling USB-C.

In her Computex keynote, Su only talked about the RYZEN 7000CPU. There is certainly more to come as the CEO has identified ASRock, ASUS, Gigabyte, Biostar and MSI as AM5 motherboard makers. Such manufacturers probably won’t bother for a single processor, and AMD has used its AM4 socket on dozens of CPUs over the past five years.

Another piece of news from the keynote was a project called Mendocino – an upcoming laptop CPU architecture targeting laptops priced between $399 and $699. AMD defines this price range as entry-level to mid-range. Su said this silicon will use a 6nm TSMC process, offer four Zen 2 cores and RDNA 2 graphics, and deliver ten hours of battery life on modest laptops.

The CEO hinted that the market is ripe for an upgrade, as buyers would prefer more than the four to six hours of unplugged operation that’s currently common on cheaper laptops. The Mendocino home kit is set to debut in the fourth quarter of 2022.

Su also emphasized that around 200 AMD-powered laptop designs will go on sale throughout 2022, for gaming, consumer and enterprise kits. She suggested that this is a sign of important momentum and an indicator that OEMs believe AMD is positively differentiating their products.

Intel isn’t holding a Computex keynote this year — an unusual omission. Nvidia has a Tuesday slot for this The registry will be attending as our APAC office is keeping tabs on the conference. ®
