AMD EPYC 7642 Benchmarks

Since the AMD EPYC 7002 series "Rome" launch at the beginning of August, it's been known how AMD's top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor.

AMD Zen 2 + Radeon RX 5700 Series For Linux Expectations

This weekend I was out the AMD E3 event learning more about their third-generation Ryzen processors as well as their equally exciting AMD Radeon RX 5700 series Navi hardware. Being at the event, one could reasonably deduce the Linux support will be great and it does appear to be that way building upon their improvements of earlier GPUs and Zen processors. It does appear to be that way while obviously we will begin testing soon of these new processors and graphics cards. At least for the Zen 2 processors, I am confident in their Linux support while on the Navi side we are awaiting Linux driver support but I am optimistic it will work out nicely. Now that the initial embargo has expired, here are more details on these new AMD products launching 7 July and my Linux information at this time.
