Intel elaborate on quad-core Yorkfield delays
…they add that “this is not acceptable for our customers that require longterm stability. It’s a showstopper.”
Previous reports of errata degrading the L2 and L3 cache performance were described as “false.” Microcode and BIOS updates issued by Intel since November do not fix or address the “showstopper” bug affecting the launch of the quad-core Q9300, Q9450 and Q9550 processors. The condition does not affect Xeon quad-core processors. Intel tells DailyTech this is because Xeon uses a different stepping than the quad-core processors, which fixes this simulated condition. The quad-core 45nm Extreme Edition processor launched in November is also unaffected.
