Processes for microprocessors for servers, Intel's plans to use DDR5, PCIe 5.0 are revealed by … Huawei


Huawei's latest action, not knowing what it means, is to release a series of information about Intel's 2022 product roadmap right at an event held by the company in St. Louis. Petersberg, Russia. The products are revealed in the server segment, namely the CPU Granite Rapids, Sapphire Rapids, DDR5 and PCIe 5.0 memory roadmap.

Accordingly, Sapphire Rapids will be the CPU line for servers using the 10 nm process to replace Ice Lake in 2021, similar to Granite Rapids will be released in 2022. Huawei also revealed memory and used communications. Use on new platforms like DDR5 and PCIe 5.0.




It is worth mentioning that the information is always confidential (Confidential), a private exchange between Huawei and Intel and obviously the US semiconductor maker will be unhappy when Huawei discloses it will affect the economic plan. Because Intel had only recently disclosed Sapphire Rapids to its shareholders, the 2022 route was only called the Next Gen, the next generation, without giving any specific information. Now that Huawei has replaced Intel to say it all, Granite Rapids will be the CPU line for the server by 2022 and it will use the 7nm process.

Sapphire Rapids uses the Willow Cove microarchitecture produced on the 10nm ++ process. Willow Cove is the replacement architecture for Sunny Cove 10nm that Intel has just introduced today, currently the microarchitecture of Ice Lake CPUs including the server CPU – Xeon series. In the document revealed by Huawei, Granite Rapids still uses Willow Cove architecture but produced on 7nm process.

The Xeon CPUs of Sapphire Rapids and Granite Rapids generation all exploit DDR5 RAM and support PCIe 5.0. What does this mean for end users? If DDR4 RAM will be replaced by DDR5 in 2021, we can expect this RAM standard to be widely used on universal computers by 2022. Automatic generation with PCIe 5.0 – PCIe generation generation 5th with bandwidth per lane of up to 4 GB / s.

Huawei is facing a ban in the US and many other countries and disclosing such confidential documents could make the situation worse. Intel also suffered under the ban imposed on the Chinese technology firm by the Trump government. According to calculations alone, Intel will lose about 83 million USD in revenue.
