Kudos to the AnandTech team for a comprehensive, objective look at the differences between x86 and Power in one of the many areas of processor performance.

The reason I like this report is that it supports my answer to the question of "How much performance benefit will <insert platform here> I get?" which always is "It depends..."

Application performance is governed by so many things -- core speed, number of threads per core, core architecture, memory bandwidth, caches sizes, cache miss impacts, numbers of caches, NUMA topology, I/O pipes, I/O technologies, adapter types, disk caching, storage types, media rates.  Then, map the application characteristics onto these factors and try to "predict" a number.  It's not easy to find "a number".

Thus, anyone who tells you simply "Platform <X> is 3 times faster than platform <Y>" is clearly in Sales or Marketing!!!
 
A really good deep dive into POWER8 and its performance compared to modern Intel CPUs.

If you did not participate in the #OpenPOWER   Summit and/or want to know more about where OpenPOWER is going, I'd strongly recommend viewing the videos from the conference.  In particular, I'd recommend Brad McCredie's presentation "OpenPOWER and the Roadmap Ahead" as well as Aaron Sullivan's "Soft-Hardare: The Foundation of Cloud 2.0" presentation.

+Ubuntu on #PowerLinux .  An exciting technology to watch...

Thanks for the excellent blog on the technology, +Breno Leitao!
Ubuntu created an interesting way of distributing binaries called snap, and the snap tool is available in Power since Ubuntu 16.04. Snap is a way to make packages available with their dependencies …

Another key component for DevOps solution: #ChefServer for #PowerLinux .
Today I’m very pleased to announce the availability of Chef Server 12.7.0 for IBM Power Systems on Linux. This marks the first time Chef Server will be generally available (GA) for Ubuntu 14.04 (little endian) and Red Hat Enterprise Linux 7.1 (big endian and little endian). The packages are available from our stable yum and …

Updated my thoughts on #PowerLinux little endian for those who still have questions and/or want an update...
by Jeff Scheel, IBM Distinguished Engineer, Linux Technical Strategy Two years ago this month, I published my first blog about the Linux on Power strategic shift from big endian to little endian, titled Just the FAQs about Little Endian , and I still get questions about it today. So, I figured it was time to make updates. The questions listed below are either updated or new. If you do not see your particular question, please read the original doc...

Interested in Device Tree information, then you might want to join the devicetree-spec@vger.kernel.org mailing list. Work has begun to revive the document.

In the future, #OpenPOWER will be providing a document with extensions used on Power Systems, but this document clearly fills a need as a building block.
Hi all, I've cut the first formal release of the devicetree specification. This is the baseline release with a bunch of editorial fixes from the v0.1-pre1 release from a few weeks ago. Now begins the task of bringing new bindings into the spec. You can find the released document here: ...
