Just before the launch of Bulldozer, AMD demonstrated it at 8.43GHz, which was the world record back then. Now an overclocker named Andre Yang has achieved an overclock of 8.46GHz, beating AMD's record by ~30MHz. 

Above are the CPU-Z screenshots of the new and former record. The exact frequency is 8461.51MHz, which is 32.13MHz faster than the previous record. As shown in the pictures, both CPUs had only two cores enabled and ASUS's Crosshair V Formula motherboard was used. Andre applied a core voltage of 1.992V, whereas AMD had a voltage of 2.016V in their setup. Cooling method of Andre's setup is unknown, but most likely either liquid nitrogen or helium was used.

    It doesn't need anything more than a dual core Phenom II.

    They've got the bolding on the second link all messed up, awarding some wins to one OS when it's actually a defeat. Interesting links though, thanks.

    Mask 55/AA is a rather intriguing idea.

    AMD already sells 65W Phenom IIs. Intel is just copying AMD's technical insights of what consumers want, as Intel has done for several years now.

    For the record Intel CPUs have had a cold defect since after Celeron and that is why they don't post 8+ GHz. CPU performance results like in this article.

    Both companies have offered lower power CPUs for years now.

    Also, didn't AMD have the cold bug until Phenom II?
  • Beenthere - Saturday, October 29, 2011 - link

    Nope, no cold Bug defect in AMD CPUs. That's why they have held the OC'ing record for years.

    While all nice and fancy, this means nothing to a normal user or even a prosumer. I'd like it to be an AMD rig when I get to upgrade and I have the "luxury" to wait and see what Piledriver brings to the table. BD needs some heavy tweaking on the idle and load power as well as the performance. Piledriver should trounce Phenom II X6 with a vengeance in every benchmark to convince me.

    What I see mentioned seldom here is that AMD has repeatedly said that a bulldozer module would do 80% of the work of a normal dual core because of shared resources. If we do a little oversimplyfied math then 8 x 80% = 6.4. I shouldn't suprise anyone that it is'nt always able to blast past the ole Phenom II X6. I think AMD built this thing for the future. The ealry dualcores didn't always outperform the single cores. Now they bring an 8-core or a sort there of that doesn't always outperform a true 6-core. My guess is it will improve when the architecture is refined (IPC, cache latency etc.) and software makes better use of the abundance of cores. It has happened before. The simple fact that there are benchmarks where BD does very well must indicate that AMD have done something right.

    Seems to me this is as much or more a marketing stunt for ASUS' Crosshair V Formula as it is for Bulldozer. I get that they are trying to show BDs scalability and in some ways they are but they are also using very restricted conditions here. Reduced numbers of cores, extreme cooling etc... You can bet that ASUS is going to use this on their packaging / marketing material for the Crosshair V, less so for BD.

    What does this have to do with anything?
    Bulldozer is still slower tha Phenom thread-to-thread.
    Only mildly interesting as a science project....
  • frozentundra123456 - Saturday, October 29, 2011 - link

    I totally agree with you. Unfortunately, every CPU article that comes up seems to get taken over by AMD fans spouting the same old justifications for AMD.

    AMD CPUs are good enough
    Intel is the evil empire and only is ahead because they used unfair practices
    Bulldozer doesnt matter on the desktop, it will be great as a serever
    What really matters is graphics
    Oh, and a new one in this thread, Intel has a Cold Bug. Gee, I will remember to be sure to get an AMD cpu for my next liquid nitrogen cooled system.

    I guess Intel prices will still sky-rocket due to the lack of competition. Hell, the 1.5 year old 980X is still rocking socks.
