Like the Pentium FDIV bug
of yesteryear, this was a real issue, but one that realistically only impacted a fraction of a fraction of buyers.
Why this matters: In the grand scheme of CPU "errata" or bugs, this one is fairly esoteric and really not worthy of being mentioned in the same paragraph as Intel's infamous 1994 FDIV bug
. The FDIV bug
would manifest itself in Microsoft Excel spreadsheets and was serious enough that Intel recalled the CPUs to the tune of millions of dollars.
