These are dog years for servers.   Pretty much every year Intel introduces a new Xeon processor.  Those who have heard the story recognize this as the Tic Tock model.  On Tic years the manufacturing process is updated, on Tock years the chip architecture is updated.  Every year customers get a boost in performance, and often a cut in power.  Typically this boost is in the 50% neighborhood, enough to make it worth the upgrade, and still achievable by engineering teams on a two year cycle.  Except, we are in dog years.

 

 

The Nehalem – Xeon 5500 – processor broke all prior boundaries on single generation performance gain.  Delivering two to three times the compute capacity of the Xeon 5400 (Harpertown) generation.  This is a big change, probably a once in a lifetime change – unless that quantum thing happens in my lifetime.  Roughly a 10X performance boost in less than 5 years.

 

During this same five years we have seen virtualization technology go from a lab project – something for test and dev – to mainstream data center process.  In 2005 it would have been heresy to suggest virtualizing the corporate ERP.  At that point virtualization overhead on the server could be as high as 25% and the entire server was needed to do “real work”.  Fast forward to today.  Virtualization technology in both the hypervisor and processor have reduced overhead to only a few percent, AND servers are 10X faster.  Not only can you virtualize the ERP, you are irresponsibly wasting resources if you do not.  Unless your ERP demands have grown 10X in 5 years, your ERP alone won’t even make a new Xeon 5500 system sweat.

 

If this advancement wasn’t enough, the announcements last month from Intel about the coming Xeon 7500 (4+ socket) processor were amazing.  All the benefits of the Xeon 5500, but on steroids.  The  new biggest leap ever.  With up to eight cores and four memory channels per socket, this is a monster.  Your ERP system will be barely a blip in perfmon.  It isn’t unreasonable that an entire data center for a SMB business could be virtualized onto one of these beasts.  And, how big is a Xeon 7500 server?  My guess is about the size of a breadbox

In my last blog I talked about working on great projects which were “special”. Special in that everyone enjoyed coming to work, they worked well together, and part of the “magic” was we all knew we were working on something revolutionary.  Well that special, revolutionary project is now available for all to see, and it is known as the Intel® Xeon® processor 5500 series and Intel Xeon® 5500 series chipset.

What amazes me the most about this project/platform is the incredible leap in performance compared to its previous generation platform which was based on the Intel Xeon processor 5400 series. For a new generation platform, 20-30% improvements in performance is typical.  And 50% vs. the previous generation platform is above normal, but the new Xeon 5500 series platform out performs the previous generation platform (Xeon 5400) by 2X or more on many benchmarks.  That’s right…nearly twice the performance!  (Click here for performance details.)

So how did they achieve this monster leap in performance? 

-          Did they double the core frequency? 

-          No…in fact core frequency has gone down slightly.

-          Did they double the number of cores?

-          No…same number of cores.

-          Did they make major changes to the CPU micro-architecture…like issuing and retiring many more instructions per clock? 

-          No.  Same 4-instruction per clock issue/retire capabilities.

-          Did they use a new silicon process technology? 

-          No…both use the same 45nm process.

-          Did they increase cache size? 

-          No…total L2 + L3 cache size actually went down (9MB vs 12MB).

 

So how did they “double’ the performance?  This is what truly amazes me.  This team was able to essentially double the performance of the platform, without changing the most obvious (e.g. # of cores, CPU frequency, major micro-architecture changes, Si process technology or cache size).  Instead, they made many changes and optimizations to the entire “platform” as well as some incremental enhancements to the processor micro-architecture (like deeper queues)…which collectively removed bottle necks in many different places and the results are nothing short of fantastic. 

The various changes added up to “major” improvements in performance.  Some of these changes are listed below…shown in comparison to the previous generation Xeon 5400 series platform which was/is no slouch.  Even today, more than a year after its introduction, the Xeon 5400 was still was the highest performing 2-scoket platform on many benchmarks.  That is until the Xeon 5500.

All I can say is wow!  And all this performance comes in a lower platform power envelope than the Xeon 5400.  The performance and power savings are a true testament to this team’s ability to work together and deliver a truly revolutionary product.
