The new Opteron 6300: Finally Tested!
by Johan De Gelas on February 20, 2013 12:03 AM ESTVirtualization Performance: Linux VMs on ESXi
We introduced our new vApus FOS (For Open Source) server workloads in our review of the Facebook "Open Compute" servers. In a nutshell, it is a mix of four VMs with open source workloads: two PhpBB websites (Apache2, MySQL), one OLAP MySQL "Community server 5.1.37" database, and one VM with VMware's open source groupware Zimbra 7.1.0. Zimbra is quite a complex application as it contains the following components:
- Jetty, the web application server
- Postfix, an open source mail transfer agent
- OpenLDAP software, user authentication
- MySQL is the database
- Lucene full-featured text and search engine
- ClamAV, an anti-virus scanner
- SpamAssassin, a mail filter
- James/Sieve filtering (mail)
All VMs are based on a minimal CentOS 6 setup with VMware Tools installed. All our current virtualization testing is on top of the hypervisor which we know best: ESXi (5.0). We have changed two things in our vApusMark FOS setup: we upgradeded the guestOS from 5.6 to 6.0 and increased the number of vCPUs of the OLAP VM from 2 to 4. This small upgrade means that our latest results should not be compared to the results in our older articles. We test with four tiles (one tile = four VMs). Each tile needs nine vCPUs, so the test requires 36 vCPUs.
For being just a minor update, the new Piledriver core does pretty well. Clock for clock performance goes up by 11%. The total performance gain (IPC+clock) is 20%, which is significant. The Opteron 6376 performs only 4% better than its direct competitor the E5-2630 (as the latter will perform very similar to our E5-2660 with 6 cores), but that is not bad at all: you get slightly better performance for a lower (server) price.
The top of the line 6380 cannot keep up with the best Xeons. Offering 86% of the more expensive Xeon E5-2660 is hardly a disaster, however. Note "maximum amount of affordable memory" is on top of many virtualization hosts shopping lists followed by price/performance. For those buyers, considering that a server based upon the Opteron cost less, the Opteron is once again a potent virtualization host if the power usage is similar.
With the lack of c-states, the Opteron 6174 did pretty poorly. The Opteron 6276 consumed a lot less at idle than its predecessor, but consumed a lot more when pressured to perform at high load. So we were very keen to learn whether AMD has improved power consumption too. Did AMD finally get that part right?

You realize that we have no trouble recognizing that you've posted about fifty comments that are essentially incompetent racism against AMD, right?AMD's processors aren't prefect, but neither are Intel's. And also, AMD, much to your dismay, never announced they were planning to get out of the x86 server market. They'll be joining the ARM server market, but not exclusively. I'm honestly just ready for x86 as a whole to be gone, completely and utterly. It's a horrible CPU architecture, but so much money has been poured into it that it has good performance for now.

x86 is fine, just fine.coder543 - Wednesday, February 20, 2013 - link
totes, ain't nobody got time for AMD. they is teh failzor.(yeah, that's what I heard when I read your highly misinformed argument.)

Obvious trolling aside, looking at the numbers and its pretty grim. Keep in mind that these are SERVER CPUs. Not only is Intel doing the job faster, its using less energy, and paying a mere $100-$300 more per CPU to cut off on average 20 watts is a no-brainer. These are expected to run 24 hours a day, 7 days a week with no stopping. That power adds up and if AMD has any chance to make any dent in the high end enterprise datacenters they need to push even more.Beenthere - Wednesday, February 20, 2013 - link
You must be kidding. TCO is what enterprise looks at and $100-$300 more per CPU in addition to the increased cost of Intel based hardware is precisely why AMD is recovering server market share.If you do the math you'll find that most servers get upgraded long before the difference in power consumption between an Intel and AMD CPU would pay for itself. The total wattage per CPU is not the actual wattage used under normal operations and AMD has as good or better power saving options in their FX based CPUs as Intel has in IB. The bottom line is those who write the checks are buying AMD again and that's what really counts, in spite of the trolling.
Rory Read has actually done a decent job so far even though it's not over and it has been painful, especially to see some talent and loyal AMD engineers and execs part ways with the company. This happens in most large company reorganizations and it's unfortunate but unavoidable. Those remaining at AMD seem up for the challenge and some of the fruits of their labor are starting to show with the Jaguar cores. When the Steamroller cores debut later this year, AMD will take another step forward in servers and desktops.

Most servers have a long life. You'll probably upgrade memory and storage, but CPU is rarely upgraded.Guspaz - Wednesday, February 20, 2013 - link
Let's assume $0.10 per kilowatt hour. A $100 price difference at 20W would take 1000 kWh, which would take 50,000 hours to produce. The price difference would pay for itself (at $100) in about 6 years.So yes, the power savings aren't really enough to justify the cost increase. The higher IPC on the Intel chips, however, might.

You're only getting part of the equation here. That extra 20w of power consumed mostly turns into heat, which now must be cooled (requiring more power and more AC infrastructure). Each rack can have over 20 2U servers with two processors each, which means nearly an extra kilowatt per rack, and the corresponding extra heat.Also, power costs can vary considerably. I was at a company paying 16-17cents in Oakland, CA. 11 cents in Sacramento, but only 2 cents in Central Washington (hydropower).

+as many as I could give. Best post!Tams80 - Wednesday, February 20, 2013 - link
I wouldn't even ask the NYSE for the time day.
