Errata are not uncommon with new processors, but a problem with the TLB logic in AMD's quad-core Opteron and Phenom processors appears to be quite serious. The errata is so severe that AMD has issued a "stop ship" order on all quad-core Opterons. AMD has also blamed it for the delay of the 2.4GHz Phenom, despite the fact that the errata is unrelated to clock speed. A BIOS-based workaround for the issue has been made available to motherboard makers, but it apparently carries a 10-20% performance penalty. What's more disturbing is that AMD knew of the errata and the potential performance hit associated with fixing it before it launched the Phenom processor. Hardware provided to the press for reviews did not include the fix, conveniently overstating Phenom performance.

在新处理器中出现错误(Errata),也就是俗称的bug,确实不算怪事,但AMD的的Opteron和Phenom的四核处理器 ...
