POWER9 & ARM Performance Against Intel Xeon Cascadelake + AMD EPYC Rome

Filed under
Graphics/Benchmarks

For those wondering how ARM and IBM POWER hardware stack up against AMD's new EPYC "Rome" processors and that of Intel's existing Xeon "Cascade Lake" processors, here is a round of tests from the POWER9 Talos II, Ampere eMAG, and Cavium ThunderX in looking at the cross-architecture Linux CPU performance currently in the server space.

Our AMD EPYC Rome benchmarks this month have been focused on the performance compared to earlier AMD EPYC and Intel Xeon processors, but given the broader architecture support on Linux and there also being significant interest in the likes of IBM POWER / OpenPOWER thanks to more open-source designs when paired with motherboards from Raptor Computing Systems, here are some initial numbers for ARM and POWER9 performance against the new x86_64 server CPUs.

A POWER'ful Announcement Is Expected Tomorrow

  • A POWER'ful Announcement Is Expected Tomorrow Changing The Open-Source Landscape

    For those interested in IBM's POWER architecture and/or open-source hardware prospects, an industry-shaking announcement is expected to happen Tuesday morning.

    Taking place Tuesday and Wednesday in sunny San Diego is the OpenPOWER Summit focused on the open-source POWER ecosystem. There will be keynotes tomorrow from IBM, Microsemi, Raptor Computing Systems, and the OpenPOWER Foundation. Beyond the usual fluff and what not at most industry events / keynotes, there is going to be a very exciting announcement made tomorrow morning in kicking off this event.

Open source POWER ISA takes aim at Intel and Arm for accelerator

  • Open source POWER ISA takes aim at Intel and Arm for accelerator-driven computing

    IBM announced the release of the POWER instruction set architecture (ISA) as an open standard at the OpenPOWER Summit in San Diego on Tuesday. This announcement comes six years after the formation of the OpenPOWER Foundation, which aimed to foster the creation of hardware from third-party vendors that integrates the POWER architecture in the datacenter.

    While the POWER ISA was itself licensable following the creation of the OpenPOWER Foundation in 2013, that came at a cost. Now, the POWER ISA is available royalty-free, inclusive of patent rights. IBM is releasing a soft core reference implementation of the POWER ISA, and reference designs for Open Coherent Accelerator Processor Interface (OpenCAPI) and Open Memory Interface (OMI) architecture-agnostic compute accelerators.

AMD EPYC 7642 Benchmarks: The Rome 48 Core CPU That Easily Takes On Intel's Xeon Platinum 8280

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. Complementing our recent EPYC 7302 and EPYC 7402 benchmarks, today we are focused on the EPYC 7642 as the Rome 48-core / 96-thread processor. This 48 core processor has a 2.3GHz base clock and 3.3GHz boost clock while having 256MB of L3 cache, eight DDR4-3200 memory channels, 128 PCIe 4.0 lanes, and other features in common with the EPYC 7742 and other Rome processors. The EPYC 7642 carries a 50MHz base clock speed advantage over the 64 core EPYC 7742 but a 100MHz lower boost clock speed as the principal differences aside from the core/thread count. Both of these CPUs carry a 225 Watt TDP. Read more

Plasma 5.16.90 (Plasma 5.17 Beta) Available for Testing

Are you using Kubuntu 19.04 Disco Dingo, our current Stable release? Or are you already running our development builds of the upcoming 19.10 Eoan Ermine? We currently have Plasma 5.16.90 (Plasma 5.17 Beta) available in our Beta PPA for Kubuntu 19.04 and 19.10. This is a Beta Plasma release, so testers should be aware that bugs and issues may exist.

Raspberry Pi 4 getting hot? A closer look

I hope that will all arrive in time for me to try it out over the weekend, so I can pass along some more information about temperatures, and about what pieces fit together in which cases, if any. Finally, the Raspberry Pi Foundation says that they are working on several software and firmware changes that should help bring the temperature of the Pi 4 down. Hopefully those will be released soon - but even if they are, I don't expect that they will improve the situation by more than 5 degrees or so, and given how hot the Pi 4 runs, that is not enough to eliminate the need for the kind of hardware measures I am looking at now.

Top Open Source Video Players for Linux

You can watch Hulu, Prime Video and/or Netflix on Linux. You can also download videos from YouTube and watch them later or if you are in a country where you cannot get Netflix and other streaming services, you may have to rely on torrent services like Popcorn Time in Linux. Watching movies/TV series or other video contents on computers is not an ‘ancient tradition’ yet. Usually, you go with the default video player that comes baked in with your Linux distribution (that could be anything). You won’t have an issue utilizing the default player – however, if you specifically want more open-source video player choices (or alternatives to the default one), you should keep reading. Read more
