  Ok the benchmark is from June 17th, 2020 but it’s using a Xeon 6140 a Skylake chip from Q3'17. That gets crushed even by even a $125.00 E5-2670 let alone whatever your similar budget buys you. So, I am guessing actual head to head benchmarks must be quite bad.

    Yes. It has a Processor Base Frequency 2.30 GHz · Max Turbo Frequency 3.70 GHz Your latest Intel® Xeon® E-2386G Processor, not available yet...has a base frequency of 3.50 GHz and a Max Turbo Frequency 5.10 GHz So even with the latest...your Turbo frequency... is the base from the mainframe core... And if you happen to be running a memory bound benchmark, with the massive caches in the mainframe, you will be crushed.

      > Running a memory bound benchmark I can easily write a memory bound benchmark that makes all CPU cache irrelevant. The only thing that actually matters is real world performance which is why actual benchmarks are so critical. > Xeon® E-2386G Processor That’s a chip from 2018. Anyway, you can talk about CPU clock speeds all day, but it doesn’t mean much between different CPU families.

      Can't reply to response from Retric below so will do it here. Wrong choice indeed the Xeon® E-2386G Processor its not what I was looking for. Instead of going for the latest lets review the latest offers from Intel: https://en.wikipedia.org/wiki/List_of_Intel_processors https://en.wikipedia.org/wiki/List_of_Intel_processors A few models that have a peak turbo frequency approaching the sustained frequency of Z core. Also, of course due to different architectures, internal caches, we should not be comparing purely on frequency. Although the mainframe is again wining here in frequency and cache sizes... Also agree that what counts are real workloads with real commercial applications. I have so far posted at least three but here is another one: "IBM MQ for z/OS on z15 Performance" http://ibm-messaging.github.io/mqperf/MQ_for_zOS_on_z15.pdf http://ibm-messaging.github.io/mqperf/MQ_for_zOS_on_z15.pdf
