AnandTech offers a visual representation of the problem, which is essentially that the task scheduler puts threads on multiple modules rather than exploiting Bulldozer’s ability to have a single module share threads. This means Windows views each dual-core block as a single core, negating Bulldozer’s competitive advantage.
In response, Microsoft announced a manual hotfix download for Windows 7 and Windows Server 2008 R2 last week, which promised to fix the task scheduler issue. That patch has since been withdrawn, with Microsoft saying it was released prematurely, with a second part not yet ready to be pushed live. This makes sense, considering that some users reported that the fix actually decreased Bulldozer performance instead of improving it (a 2-7% increase had been touted).
Microsoft is reportedly working on an updated version – and the issue is already addressed in Windows 8 and Windows Server 8. The effort to support Bulldozer shows that the company has not given up on AMD just yet; but it remains to be seen how the rest of the market will respond.
Do you think AMD can compete in the Windows Server chip market – or is Bulldozer dead on arrival, with or without this fix? Tell us in the comments, or on Twitter @WindowsTT.]]>
It’s not too hard to predict what the hot topics will be for Windows admins in 2012 (they have much in common with what we thought would be big in 2011). What is tricky, though, is determining how these new and updated technologies will impact how jobs get done – both on a daily basis and in the long term. That’s when we turn to the experts.
Over the next few weeks, we’ll be talking to our esteemed group of contributors to find out what challenges IT pros will face next year – but we want to hear from you, too. What skills are you learning now? What upgrades do you plan to make? What’s on the horizon that makes you excited…or nervous?
