How Can AMD EPYC "Rome" 7002 Series Be Even Better? Open-Source BIOS / Coreboot

Phoronix - 8. Srpen 2019 - 12:00
By now you've likely seen the fantastic performance out of AMD's new "Rome" 7002 series processors. The performance is phenomenal and generally blowing well past Intel's Xeon Cascade Lake processors. So that's all good and it can get even better outside of performance: I asked AMD about the prospects of Coreboot / open-source BIOS support and got a surprising response...

Phoronix - 8. Srpen 2019 - 0:00
One month ago today we were talking about the AMD Ryzen 3000 series processor and new Radeon RX 5700 series graphics cards, all manufactured on TSMC's 7nm process. Today, for 7th August, the embargo has now lifted and we are talking about something arguably more exciting, or at least the ability to more profoundly impact an industry (data centers): AMD's EPYC 7002 series is ready and their line-up and ultimately the resulting performance is the most exciting and competitive we have seen ever out of AMD in the server space.

Initial Benchmarks Of The Spectre "SWAPGS" Mitigation Performance Impact

Phoronix - 7. Srpen 2019 - 14:30
Yesterday the SWAPGS vulnerability was made public as a new variant of Spectre V1 that affects all operating systems and is believed to affect only Intel CPUs. The SWAPGS discovery by Bitdefender was quietly mitigated by Microsoft for Windows 10 last month while yesterday the patches were posted for the mainline Linux kernel as the Grand Schemozzle. As soon as learning of this SWAPGS vulnerability and seeing the kernel code, I began running some preliminary performance tests to look at the impact of this latest CPU mitigation.
