The new Opteron 6300: Finally Tested!by Johan De Gelas on February 20, 2013 12:03 AM EST
Unfortunately, the Intel R2208GZ4GSSPP is a 2U server, which makes it hard to compare it with the 1U Opteron "Interlagos" and 1U "Westmere EP" servers we have tested in the past. We will be showing a few power consumption numbers, but since a direct comparison isn't possible, please take them with a grain of salt.
Intel's Xeon E5 server R2208GZ4GSSPP (2U Chassis)
|CPU||Two Intel Xeon processor E5-2660 (2.2GHz, 8c, 20MB L3, 95W)|
|RAM||64GB (8x8GB) DDR-1600 Samsung M393B1K70DH0-CK0|
|Motherboard||Intel Server Board S2600GZ "Grizzly Pass"|
|BIOS version||SE5C600.86B (01/06/2012)|
|PSU||Intel 750W DPS-750XB A (80+ Platinum)|
The Xeon E5 CPUs have four memory channels per CPU and support DDR3-1600, and thus our dual CPU configuration gets eight DIMMs for maximum bandwidth. The typical BIOS settings can be found below.
Not visible in the above image is that all prefetchers are enabled in all of the tests.
Supermicro A+ Opteron server 1022G-URG (1U Chassis)
Two AMD Opteron "Abu Dhabi" 6380 at 2.5GHz
Two AMD Opteron "Abu Dhabi" 6376 at 2.3GHz
Two AMD Opteron "Bulldozer" 6276 at 2.3GHz
Two AMD Opteron "Magny-Cours" 6174 at 2.2GHz
|RAM||64GB (8x8GB) DDR3-1600 Samsung M393B1K70DH0-CK0|
|Internal Disks||2 x Intel MLC SSD710 200GB|
|Chipset||AMD Chipset SR5670 + SP5100|
|BIOS version||v2.81 (10/28/2012)|
|PSU||SuperMicro PWS-704P-1R 750Watt|
The same is true for the latest AMD Opterons: eight DDR3-1600 DIMMs for maximum bandwidth. You can check out the BIOS settings of our Opteron server below.
C6 is enabled, TurboCore (CPB mode) is on.
ASUS RS700-E6/RS4 1U Server
Two Intel Xeon X5670 at 2.93GHz—6 cores
Two Intel Xeon X5650 at 2.66GHz—6 cores
|RAM||48GB (12x4GB) Kingston DDR3-1333 FB372D3D4P13C9ED1|
|BIOS version||1102 (08/25/2011)|
|PSU||770W Delta Electronics DPS-770AB|
To speed up benchmarking, we tested the Intel Xeon and AMD Opteron system in parallel. As we didn't have more than eight 8GB DIMMs, we used our 4GB DDR3-1333 DIMMs. The Xeon system only gets 48GB, but this isn't a disadvantage as our highest memory footprint benchmark (vApus FOS, 5 tiles) uses no more than 40GB of RAM. There is no real alternative as our Xeon has three memory channels and cannot be outfitted with the same amount of RAM as our Opteron 6300 or Xeon E5 system (four channels).
Common Storage System
For the virtualization tests, each server gets an Adaptec 5085 PCIe x8 card (driver aacraid v1.1-5.1 b 469512) connected to six Cheetah 300GB 15000 RPM SAS disks (RAID-0) inside a Promise JBOD J300.
All vApus testing is done on ESXi vSphere 5--VMware ESXi 5.1. All vmdks use thick provisioning, independent, and persistent. The power policy is "Balanced Power" unless otherwise indicated. All other testing is done on Windows 2008 Enterprise R2 SP1. Unless noted otherwise, we use the "High Performance setting" on Windows 2008 R2 SP1.
Both servers are fed by a standard European 230V (16 Amps max.) powerline. The room temperature is monitored and kept at 23°C by our Airwell CRACs. We use the Racktivity ES1008 Energy Switch PDU to measure power consumption. Using a PDU for accurate power measurements might seem pretty insane, but this is not your average PDU. Measurement circuits of most PDUs assume that the incoming AC is a perfect sine wave, but it never is. However, the Rackitivity PDU measures true RMS current and voltage at a very high sample rate: up to 20,000 measurements per second for the complete PDU.

sherlockwing - Wednesday, February 20, 2013 - linkThese 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 - linkIvy 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.
Oskars Apša - Wednesday, February 20, 2013 - linkWasn'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
Beenthere - Wednesday, February 20, 2013 - link...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.
JohanAnandtech - Thursday, February 21, 2013 - linkSeaMicro 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 - linkFixed. Thanks for pointing it out, always appreciated.
Death666Angel - Wednesday, February 20, 2013 - linkHey!
I get a " Page Not Found" error from the Racktivity PDU link. :)
ssj3gohan - Wednesday, February 20, 2013 - linkYou 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)
