Multi-Core Scaling Performance Of AMD's Bulldozer @ Phoronix

Posted on Wednesday, October 26 2011 @ 13:30:58 CEST by


Phoronix checks out the multi-core performance of AMD's new Bulldozer architecture in Linux, you can check out the results over here. The site concludes the AMD FX-8150 doesn't scale as well as a true eight-core configurations (i.e. dual quad-core Opterons) but for most multi-core workloads the chip is quite competitive.
"There has been a lot of discussion in the past two weeks concerning AMD's new FX-Series processors and the Bulldozer architecture. In particular, with the Bulldozer architecture consisting of "modules" in which each has two x86 engines, but share much of the rest of the processing pipeline with their sibling engine; as such, the AMD FX-8150 eight-core CPU only has four modules. In this article is a look at how well the Bulldozer multi-core performance scales when toggling these different modules. The multi-core scaling performance is compared to AMD's Shanghai, Intel's Gulftown and Sandy Bridge processors."
