The new Opteron 6300: Finally Tested!
by Johan De Gelas on February 20, 2013 12:03 AM ESTRendering Performance: Cinebench
Cinebench, based on MAXON's CINEMA 4D software, is probably one of the most popular benchmarks around as it is pretty easy to perform this benchmark on your own home machine. The benchmark supports 64 threads, more than enough for our 24- and 32-thread test servers. First we test single-threaded performance, to evaluate the performance of each core.
Cinebench achieves an IPC between 1.4 and 1.8 and is mostly dominated by SSE2 code. The new Opteron is clock-for-clock about 3% more efficient. Let's check out the multi-threaded score.
The Opteron 6300 is about 6% faster than its predecessor at the same clockspeed. People in the rendering market tend to go for the best and still affordable performance. A few hundred dollars more can easily be recouped if your rendering is finished earlier. This remains Intel territory.

I have dual Opteron 6344 workstation system, which tends to be either near complete idle or near complete busy, so C states are extremely important to me. The CPU has power sensors that are exposed in Linux using the 'sensors' tool. With C6 enabled, I get the power consumption per socket down to 42 Watts, which still seems like a lot, but disabling C6 made it jump to 104W per socket, when under 100% load it is constantly within 1W of the 115W TDP limit.I did not see a significant impact of C1E, neither with C6 enabled nor disabled, presumably because I rarely have cores that are idle for a short period.
More annoying to me is the lack of S3 suspend mode, the system still consumes around 100W on S1.

The difference I believe is that you cannot use AES-NI instructions when using Twofish and serpent. I guess that AMD's AES-NI implementation is just slower.JohanAnandtech - Wednesday, February 20, 2013 - link
Sounds reasonable. The question is then why Twofish and serpent are so fast on the Opteron. They probably scale very well with cores.Yorgos - Wednesday, February 20, 2013 - link
I've been abandoning tech sites due to stupid posters and internet trolls.There is so much addition info and questions in the comments and I don't know why are you letting people ruin that feature from your site?
You should make a ranking system(similar to /. ) for users, in order to automatically hide someone's comments, so we don't have to double check every time the poster and/or the comment.
I feel stupid for making that type of comment, also reading specific stupid opinions, below that article.

I like your ideas, however most of the laugh (or should I say cringe?) worthy comments would be hidden and the entertainment value would be tainted by having to click the Show button all the time. ;)lwatcdr - Wednesday, February 20, 2013 - link
Or requiring real names.JohanAnandtech - Wednesday, February 20, 2013 - link
I had meetings and people visiting me, so I could not "baby sit" the reactions. But if you don't react to the offensive message we can delete them. So the best way to deal with th trolls is to ignore. Sooner or later, they will be banned.coder111 - Wednesday, February 20, 2013 - link
Because some of the people posting here are obviously trolling for Intel and do not bring anything constructive to the discussion.MonkeyPaw - Wednesday, February 20, 2013 - link
Yes, it is quite pathetic. An ignore button would take care of this situation nicely.iamezza - Wednesday, February 20, 2013 - link
An ignore button and a report button would be great!
