Taking many by surprise was the news last week of CentOS 8 being EOL'ed next year as what has been a popular downstream of Red Hat Entrprise Linux that is free of charge and often adapted for use within large organizations. Instead, IBM-owned Red Hat is looking to position CentOS "Stream" in front of RHEL as its upstream. That still isn't sitting over well for many and today is a new post on the CentOS Blog...

While the talk in recent weeks has been about the performance of Apple's M1 ARM chip and then rumors there might be a 32 core chip in the pipe, there is already something much stronger: Ampere Altra has begun shipping and its flagship 80-core SoC with up to two sockets per server can easily take on the AMD EPYC 7742 "Rome" and Intel Xeon Platinum 8280 "Cascade Lake" performance across a variety of workloads. Here is our initial look at the Ampere Altra performance on Linux in our independent performance benchmarks.
