The new Opteron 6300: Finally Tested!
by Johan De Gelas on February 20, 2013 12:03 AM ESTLS-DYNA
LS-DYNA is a "general purpose structural and fluid analysis simulation software package capable of simulating complex real world problems", developed by the Livermore Software Technology Corporation (LSTC). It is used by the automobile, aerospace, construction, military, manufacturing and bioengineering industries. Even simple simulations take hours to complete, so even a small performance increase results in tangible savings. Add to this the fact that many of our readers have been asking that we perform some benchmarking with HPC workloads and we have reasons enough to include our own LS-DYNA benchmarking.
These numbers are not directly comparable with AMD's and Intel's benchmarks as we did not perform any special tuning besides using the message passing interface (MPI) version of LS-DYNA (ls971_mpp_hpmpi) to run the LS-DYNA solver to get maximum scalability. This is the HP-MPI version of LS-DYNA 9.71. Our first test is a refined and revised Neon crash test simulation.
The second test is the "Three Vehicle Collision Test" simulation, which runs a lot longer.
Both test paint a similar picture. The new Opteron 6376 is 5% to 7% faster than the Opteron 6276. The best AMD Opteron (6380) is about 16% faster than the previous one (6276). Not bad at all, but HPC buyers are typically categorized as either going after top performance or searching for the best performance per dollar.
The first category will go after the best Xeon E5s like the Xeon E5-2690 or the 2670 (2.6GHz, 115W) if the former's power usage is too high to fit in the dense server chassis. The second category can get 10% higher performance (E5-2660 vs 6380) for a few hundred dollars more. It is close, but it is probably not convincing enough to go for AMD. Most professional buyers need a bigger incentive before they will choose the underdog over the market leader.
HPC people are less concerned about energy consumption, but even HPC data centers run into cooling and energy supply limitations. Next stop, high performance energy consumption measurements.

These Piledriver based Opterons look competitive but the threat of Ivy-EP is immenient. The last time Intel die-shrunk their High end platform they introduced the monsterous 10 core Westmere-EP(the current Xeon E7 lineup), I wouldn't be surprised Ivy-EP introduces 10/12 core extreme E7 Xeons as well as Octa Xeons with better performance/watt.Kevin G - Wednesday, February 20, 2013 - link
Ivy Bridge-E is indeed coming but it is looking to be 6 months out. These Opterons were shipping since November which would give them a 10 month lead time. The real question for AMD is what they'll have in response in that time frame. Steamroller based parts all look to be released in 2014. On the bright side, AMD should be pairing those chips with a new socket as DDR4 becomes available.One thing though about Ivy Bridge-E is that it will also be a socket 2011 part so migration to it should get relatively quick in comparison to the Westmere-EP to Sandybridge-E transition. The same cost savings for OEM noted in this article for socket G32 Opterons will apply to Ivy Bridge-E this time around.

Wasn't intels 2011 socket to be only physically identical, but electrically totally redesigned?Hrel - Friday, February 22, 2013 - link
"These Opterons were shipping since November"I reject this statement. Nothing counts as being "on the market" until Anandtech has done a full review of it. That's my stance and I'm sticking to it :P

...is that the 63xx series is focused primarily on micro servers where it fits well. If the just disclosed Jaguar cores are any indication of AMD products to be released this and next year, I'd say AMD is back in the game in many PC and portable markets.The only thing Ivy Bridge has going for it is reduced power but at a price penalty.

SeaMicro was indeed one of first to use Piledriver based cores, but I don't think the Opteron 6300 is meant to be a "typical" microserver CPU. Otherwise, AMD would have focused more on low power parts. This meant to be an update for the general server market.Jovec - Wednesday, February 20, 2013 - link
... as it is showing the multi-threaded chart instead.JohanAnandtech - Wednesday, February 20, 2013 - link
Fixed. Thanks for pointing it out, always appreciated.Death666Angel - Wednesday, February 20, 2013 - link
Hey!I get a " Page Not Found" error from the Racktivity PDU link. :)

You say that AMDs bad implementation of C6 costs them in the energy efficiency tests, but AFAIK with a low of still 10% CPU the CPU should not enter ACPI C3 (Intel C6), it will probably stay in C1e providing there is still more than enough workload to do on each OS tick.If the xeons are observed to go into ACPI C3, then that is very probably a scheduler optimization specific for intel processors, not an actual implementation problem by AMD. Balancing C-state transitions - especially complete core sleep modes like ACPI C3 - is a notoriously hard task to do because each transition also costs a certain amount of mJ that, on immediate wake, are wasted compared to just leaving the cores in C1(e)
