With last week's dramatic EPYC "Rome" launch where AMD has blown past Intel Xeon "Cascadelake" performance in a majority of server benchmarks, helping the successful launch of these Zen 2 server processors has been Intel's repeated delays of 10nm/Icelake CPUs and also the Spectre / Meltdown / Zombieload / Foreshadow mitigations. Out of curiosity, I've run some unmitigated benchmarks for the various relevant CPU speculative execution vulnerabilities on both the Intel Xeon Platinum 8280 Cascadelake and AMD EPYC 7742 Rome processors for seeing how the performance differs.

If you didn't have a chance since last night to check out our benchmarks of the AMD EPYC 7742 and EPYC 7502 Linux performance, I certainly encourage you to do so. Even if you aren't a server enthusiast, it's incredible to see the engineering achievement of AMD with Zen 2 and how the race is certainly back on in the CPU space. If you are short on time, here's the quick summary of our initial AMD EPYC 7002 benchmark results...

Now that you have read our AMD EPYC "Rome" 7002 series overview, here is a look at the initial performance benchmarks from our testing over the past few weeks. This testing focused on the new AMD EPYC 7502 and EPYC 7742 processors in both single (1P) and dual (2P) socket configurations using AMD's Daytona server reference platform. Tests were done on Ubuntu Linux and compared to previous AMD EPYC processors as well as Intel Xeon Scalable.

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.

Today is a wild one for open-source/Linux users. Let's begin with the unexpected news: NVIDIA is releasing more GPU hardware documentation at long last! Yes, freely-available hardware interface documentation to assist in the development of the open-source NVIDIA Linux driver (Nouveau)...

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.
