I have been working with the supercomputers, Mach-1 and Mach-2 in Johannes Kepler University Linz. The CPU of Mach-1 can be found in http://www.linzwiki.at/wiki/MACH/ . Right now there are no specific types of the supercomputer, but actually, they are 8-core Intel® Xeon® Processor E7-8837 (E7 in the flowing) which is released in Q2, 2011. The CPUs of Mach-2 are 8-core Intel Xeon E5-4650 @ 2.70GHz (E5) Which is released in Q2′ 2015. According to the website https://www.cpubenchmark.net/ , the PassMark of CPU maker of four E7s is about 12698. And for a single E5, the value is 11685. If we take a look at the CPU of PC, we can found that one 12-core AMD Ryzen 7 3700X has a higher CPU marker as 23840 which is much higher compared to the previous two CPUs.
What a shame of the supercomputer that I would like to buy a workstation now, instead of to use the supercomputer.
