Rendering: Cinebench 11.5

The old Cinebench 10 benchmark was limited to 16 threads. Luckily, the new Cinebench 11.5 does not have that limitation. Cinebench only represents a very small part of the 3D Animation market, but the advantage is that this a benchmark that you can perform at home too.

Cinebench 11.5

Although the Opteron 6174 manages to stay close to the newest Xeon, the Xeon is the CPU to get. The reason is that the performance difference will grow as you are rendering smaller and less complex scenes. In those cases, the percentage of the serial code will increase. And Amdahl’s law is unrelenting: in that case the CPU with the highest single threaded performance will win. You also get the benefit of higher single threaded performance when you are modeling.

    It should be noted that newer nehelam based processors have specific AES encryption instructions. The benchmark where the xeon blows everything out of the water is likely utilizing that instruction set (though, AFAIK not many real-world applications do) Reply

    I read that Intel is expected to launch the 8-core Nehalem EX today. It'll be interesting to compare it against the 12-core Magny Cours. Both are on a 45nm process. Reply

    You stated "... that kind of bandwidth is not attainable, not even in theory because the next link in the chain, the Northbridge ...".

    How does the Northbridge affect memory BW if the memory is connected directly to the processor?

    Depending on your definition, the nortbridge is in the CPU. AMD uses "northbride" in its own slides to refer to the part where the memory controller etc. resides. Reply

    Why don't you add STREAM and LINPACK to your benchmark suites? These are very important benchmarks for HPC.

    Stream... in the review. Reply

    Hi Johan,
    For last few days I did several tests with Swingbench CC with similar database configuration but I achieved a bit different results, I’m just wondering what exactly settings you put for CC test itself. I mean about when you generate schema and data for that test? Thanks for answer.

    Your question is not completely clear to me. What is the info you would like? You can e-mail if you like at johanATthiswebsitePointcom Reply

    Can't figure out if hyperthreading were enabled on Intels. Particularly interested in virtualization benchmark with hyperthreading both enabled and disabled. Also of interest would be an Office benchmark with a bunch of small VMs (1.5 to 2GB) to simulate VDI configuration. Reply

    Hyperthreading is always on. But we will follow up on that. A VDI based hypervisor tests is however not immediately on the horizon. The people of the VRC project might do that though. Google on the VRC project.
