AMD reveals 5nm Ryzen 7000 powered by Zen 4 cores

AM5 socket to bring desktop CPUs to life in late 2022, mid-range laptop CPU to follow

AMD has revealed some more details about its forthcoming Ryzen 7000 family of Zen 4 desktop processors and the socket they'll use.

CEO Lisa Su said the chips' CPU dies will be built using a 5nm process by TSMC, will double the cache per core to 1MB, will include instructions tuned to the needs of artificial-intelligence applications, and will boast clock speeds than can top 5GHz.

The CPU chiplets will sit next to a 6nm IO die that integrates RDNA 2 graphics with silicon needed to talk to DDR5 memory and drive PCIe 5.0 interfaces. The chips are due to arrive in Q4 2022.

The processors will find a home in AM5 sockets – AMD's first socket since 2017's AM4. AM5 uses land grid array (LGA) tech and boasts 1,718 pins. Motherboards using the kit will offer up to 24 PCIe lanes and 14 USB interfaces – some at 20GB/s and all capable of handling USB-C. In her Computex keynote, Su focused on the Ryzen 7000 family, and name-checked ASRock, ASUS, Gigabyte, Biostar, and MSI as making AM5 motherboards.

Another nugget of news from the keynote was a project named Mendocino – an effort to craft a PC processor aimed at laptops priced from $399 to $699. AMD defines that price range as spanning entry-level to midrange. 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 for modest notebooks.

The CEO suggested the market is ripe for an upgrade, as buyers would prefer more than the four-to-six hours of unplugged operations that are currently common on lower-priced laptops. Mendocino kit will debut in Q4 2022.

Su also emphasized that some 200 AMD-powered laptop designs will go on sale during 2022, across gaming, consumer, and enterprise kit. She suggested that's a sign of important momentum, and an indicator that OEMs believe AMD positively differentiates their products.

Intel's not delivering a Computex keynote this year – an unusual omission. Nvidia has a Tuesday slot that The Register will attend as our APAC bureau keeps its eye on the conference. ®

    As the House of Zen kills off consumer-friendly non-Pro TR chips

    A drought of AMD's latest Threadripper workstation processors is finally coming to an end for PC makers who faced shortages earlier this year all while Hong Kong giant Lenovo enjoyed an exclusive supply of the chips.

    AMD announced on Monday it will expand availability of its Ryzen Threadripper Pro 5000 CPUs to "leading" system integrators in July and to DIY builders through retailers later this year. This announcement came nearly two weeks after Dell announced it would release a workstation with Threadripper Pro 5000 in the summer.

    The coming wave of Threadripper Pro 5000 workstations will mark an end to the exclusivity window Lenovo had with the high-performance chips since they launched in April.

  • Intel is running rings around AMD and Arm at the edge
    What will it take to loosen the x86 giant's edge stranglehold?

    Analysis Supermicro launched a wave of edge appliances using Intel's newly refreshed Xeon-D processors last week. The launch itself was nothing to write home about, but a thought occurred: with all the hype surrounding the outer reaches of computing that we call the edge, you'd think there would be more competition from chipmakers in this arena.

    So where are all the AMD and Arm-based edge appliances?

    A glance through the catalogs of the major OEMs – Dell, HPE, Lenovo, Inspur, Supermicro – returned plenty of results for AMD servers, but few, if any, validated for edge deployments. In fact, Supermicro was the only one of the five vendors that even offered an AMD-based edge appliance – which used an ageing Epyc processor. Hardly a great showing from AMD. Meanwhile, just one appliance from Inspur used an Arm-based chip from Nvidia.

  • ZTE intros 'cloud laptop' that draws just five watts of power
    The catch: It hooks up to desktop-as-a-service and runs Android – so while it looks like a laptop ...

    Chinese telecom equipment maker ZTE has announced what it claims is the first "cloud laptop" – an Android-powered device that the consumes just five watts and links to its cloud desktop-as-a-service.

    Announced this week at the partially state-owned company's 2022 Cloud Network Ecosystem Summit, the machine – model W600D – measures 325mm × 215mm × 14 mm, weighs 1.1kg and includes a 14-inch HD display, full-size keyboard, HD camera, and Bluetooth and Wi-Fi connectivity. An unspecified eight-core processors drives it, and a 40.42 watt-hour battery is claimed to last for eight hours.

    It seems the primary purpose of this thing is to access a cloud-hosted remote desktop in which you do all or most of your work. ZTE claimed its home-grown RAP protocol ensures these remote desktops will be usable even on connections of a mere 128Kbit/sec, or with latency of 300ms and packet loss of six percent. That's quite a brag.
