The main processors’ clock speed has in fact increased from 5.2 GHz in the IBM z16 to 5.5 GHz in the IBM z17. Please note that these systems are designed to operate continuously for their entire lives at these extremely high clock speeds provided your data center doesn't drift outside typical industry standard environmental limits. (Outside environmental limits the system will defend itself if/as necessary, first by slowing down then by shutting down. And the system will try to warn operators that's what's happening — and notify IBM if you have Remote Support Facility a.k.a. "Call Home" enabled.) It's not some "turbo mode" clock speed that you only get for 5 seconds after you start using the processors. As others have astutely pointed out, the clock speed is only one aspect of processor performance and throughput. Many other design factors are at least as important. However, if you'd like to applaud the amazing designers and engineers who figured out how to increase the lofty clock speed to be even loftier, I'm sure they'd appreciate it. ————— Timothy Sipples Senior Architect Digital Assets, Industry Solutions, and Cybersecurity IBM Z/LinuxONE, Asia-Pacific [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
