AMD FX-8350 with 8 cores, 8 threads, and a 4 GHz base frequency. It was launched in 2012 and supports DDR3 memory. Top tier in its day. Thank God for competition.
AMD now "owns" over 70% of the data center servers for the large, multi-national bank I work for. That's over 25,000 servers, 18,000'ish Linux, the remainder Windows.
Of the Linux servers, about 14,000 oof them are RedHat, I've been advocating for Ubuntu for at least 4 years now. Made a dent with 4,000'ish Ubuntu Linux Servers so far. As we migrate to the cloud (Azure & AWS) Ubuntu Linux Servers are preferred over RedHat. I'm just not a fan of anything IBM, nor have I been for well over 20 years now.
