Bulldozer for Servers: Testing AMD's "Interlagos" Opteron 6200 Series
by Johan De Gelas on November 15, 2011 5:09 PM ESTRendering Performance: 3DSMax 2012
As requested, we're reintroducing our 3DS Max benchmark. We used the "architecture" scene which is included in the SPEC APC 3DS Max test. As the Scanline renderer is limited to 16 threads, we chose the iray render engine, which is basically an automatically configuring Mental Ray render engine. Note that these numbers are in no way comparable to the ones we have obtained before as those were all performed with the scanline render engine!
We rendered at 720p (1280x720) resolution. We measured the time it takes to render 10 frames (from 20 to 29) with SSE enabled. We recorded the time and then calculated (3600 seconds * 10 frames / time recorded) how many frames a certain CPU configuration could render in one hour. All results are reported as rendered images per hour; higher is thus better. We used the 64-bit version of 3ds Max 2008 on 64-bit Windows 2008 R2 SP1.
Something really weird happened here: once we disable CMT, the Opteron 6276 performs much better. Rendering performance is quite good as the Opteron 6276 beats the Xeon X5650.

I'm curious if CPU-Z polls the hardware for this information or if it queries a database to fetch this information. If it is getting the core and thread count from hardware, it maybe configurable. So while the chip itself does not use Hyperthreading, it maybe reporting to the OS that does it by default. This would have an impact in performance scaling as well as power consumption as load increases.MrSpadge - Tuesday, November 15, 2011 - link
They are integer cores, which share few ressources besides the FPU. On the Intel side there are two threads running concurrently (always, @Stuka87) which share a few less ressources.Arguing which one deserves the name "core" and which one doesn't is almost a moot point. However, both designs are nto that different regarding integer workloads. They're just using a different amount of shared ressources.
People should also keep in mind that a core does not neccessaril equal a core. Each Bulldozer core (or half module) is actually weaker than in Athlon 64 designs. It got some improvements but lost in some other areas. On the other hand Intels current integer cores are quite strong and fat - and it's much easier to share ressources (between 2 hyperthreaded treads) if you've got a lot of them.

but on Intel side there are only 4 real cores with HT off or on (on an i7 920 seems to give an benefit, but on results for the second gen 2600k HT seems less important)where as on amd there are 4 cores with each core having 2 FP in them (desktop cpu) issue is the FPs are 10-30% slower then an Phenom cpu clocked at the same speed

which version of windows 2008 R2 SP1 x64 was used enterprise/datacenter/standard?Lord 666 - Tuesday, November 15, 2011 - link
People who are purchasing SB-E will be doing similar stuff on workstations. Where are those numbers?Kevin G - Tuesday, November 15, 2011 - link
Probably waiting in the pipeline for SB-E base Xeons. Socket LGA-2011 based Xeon's are still several months away.Sabresiberian - Tuesday, November 15, 2011 - link
I'm not so sure I'd fault AMD too much because 95% of the people that their product users, in this case, won't go through the effort of upgrading their software to get a significant performance increase, at least at first. Sometimes, you have to "force" people to get out of their rut and use something that's actually better for them.I freely admit that I don't know much about running business apps; I build gaming computers for personal use. I can't help but think of my Father though, complaining about Vista and Win 7 and how they won't run his old, freeware apps properly. Hey, Dad, get the people that wrote those apps to upgrade them, won't you? It's not Microsoft's fault that they won't bring them up to date.
Backwards compatibility can be a stone around the neck of progress.
I've tended to be disappointed in AMD's recent CPU releases as well, but maybe they really do have an eye focused on the future that will bring better things for us all. If that's the case, though, they need to prove it now, and stop releasing biased press reports that don't hold up when these things are benched outside of their labs.

The problem is that a lot of server folks buy new servers to run the current or older software faster. It is a matter of TCO: they have invested a lot of work into getting webapplication x.xx to work optimally with interface y.yy and database zz.z. The vendor wants to offer a service, not a the latest technology. Only if the service gets added value from the newest technology they might consider upgrading.And you should tell your dad to run his old software in virtual box :-).

Ah I hadn't thought of it in terms of services, which is obvious now that you say it. Thanks for educating me!;)

amd was shooting to capture 25% of the market? (this was like when the first amd64 chips came out)
