AMD launched Bulldozer about a month ago, but the initial CPUs were only for desktops. As a follow up, AMD has today released the server variants of Bulldozer. There are a total of 18 CPUs launching today, and they are branded as Opteron 4200 and 6200 series, although some of you may be more familiar with the codenames "Valencia" and "Interlagos". AMD actually began the shipments of 4200 and 6200 series in September but the lineup was not officially released until today. Below is a specification table.

6274 16/16 2.2GHz 3.2GHz 16MB 115W $639
6276 16/16 2.3GHz 3.3GHz 16MB 115W $788
6282 SE 16/16 2.6GHz 3.5GHz 16MB 140W $1,019

We did an overview of Bulldozer lineup in our Details on AMD Bulldozer: Opterons to Feature Configurable TDP article. The basics are still the same. 4200 series is compatible with 4100 series' C32 socket; and 6200 series is compatible with 6100 series' G34 socket. That means existing motherboards are compatible with the new CPUs, although a BIOS update may be needed. The main difference between 4200 and 6200 series, on top of the core count, is the CPU configuration support: 4200 is limited to dual CPU configuration whereas 6200 series supports up to four CPUs in one system. 6200 also has a quad-channel memory controller, whereas 4200 is limited to two channels. 

While Bulldozer was a letdown for desktops, it may be more attractive for servers. The biggest shortage of Bulldozer was its poor single-threaded performance, but server software is usually well threaded and can hence take advantage of all Bulldozer's cores. 

Johan has received Opteron 6276 CPU and is already working on a review, so stay tuned!

    You do the same thing on every forum, talk whole day without proof. Where is the proof, or link or anything. Either put up or shut up.

    He's too busy file sharing to care. ;)

    I'd love to see a box like the HP MicroServer with a 4256 EE in it.

    Interesting. I was about to say I want that CPU in a silent(-ish) 1U chassis like the Asus RS100 but with hotswap drives. Alternatively I'd be down with the MicroServer, too.

    Hell of a CPU for a 2S system if you ask me. 1S would be fine for me, too.

    Kristian, perhaps you could add those two columns for a better overview.
  • Kristian Vättö - Monday, November 14, 2011 - link

    Added! AMD's CPU database didn't have this info, hence I originally left it out.
  • gevorg - Monday, November 14, 2011 - link

    The 16-core Opteron for half a grand is quite amazing.
  • Marlin1975 - Monday, November 14, 2011 - link

    The 4200 is a dual memory CH system while the 6200 is 4ch memory. So the 6200 could stand out a lot more, performance wise, on some server task. I think that could be a hugh "main difference between 4200 and 6200".

    Also if the 4ch memory system is working well could AMD put that in the desktop system for Trinty to help the onboard video.

    It's pointed out in the article I linked ;-) I added it anyway.

    Please run more HPC benchmarks.
