Old, not obsolete: IBM takes Linux mainframes back to the future

Re: I'll root for anything not Intel

No, the Rockhopper Mainframe goes only up to 10TB RAM, which is not the equivalent of an Xeon. Intel Xeon 8-socket E7v3 goes up to 12 TB RAM, surpassing IBM Mainframes.

BTW, I dont understand why any new customer would want to use IBM Mainframes to run Linux? x86 are much much cheaper, and the Intel cpus are at least twice as fast as Mainframe cpus. So, Mainframe cpus are much slower, and Mainframes cost extremely much more than x86. So what is the use case of using an Mainframe running Linux over x86 servers? I dont get it. Sure, Mainframes have much better RAS and I/O throughput, but is that worth paying $millions for?
