Yeah these kind of errors happen all the time...when they happen the CPU will ussually just redo the operation and, providing it worked the second time, go on about its business. We don't notice a few cycles out of billions getting wasted.

This really isn't anything to hold against bulldozer based CPUs...unless these errors are very common and happen every other clock or something.

These lists are released so software and firmware writers can patch the problems that way.

Most of the time the errors are phenomenally unlikely to happen in the first place, and patched software/firmware is incapable of telling the CPU to do anything that would prompt them anyway.

Still, this sort of errata, and the fact that it takes years after release to find all the bugs, is one of the reasons why embedded systems often use really old CPU architectures. For example, Intel didn't stop making 386s until a few years ago, because people still buy them. One of the reasons they do this is because the chips are simple and have been around for over 20 years, so everyone knows them inside and out and will effectively never run into any surprise bugs.

people are still in denial about bulldozer suckage?

I don't see anyone in this thread being in denial. Everyone is just stating the obvious, Bulldozer sucks and is a pipe cleaner product. Piledriver might suck too, though.

- Fixed

Nothing new here. Every CPU has bugs and errors that can't/won't be fixed. However, they are generally incredibly rare so there's no point worrying about it.

Just curious what you mean by pipe cleaner product?

Craploads of bugs, good theoretical performance but is utterly diminished by the bugs and bad execution. How I see it, is that AMD only released Bulldozer to fix all the bugs and such to come back after a generation or two.

It took them 6 years to make a pipe cleaner product. *sigh*

Every CPU has a bunch of errata. The irrational BD hate train is becoming excessive.

But how'd it get the term "pipe cleaner"?
