Projected cost is $1 billion.
Read from bit-tech:
The $300m figure mentioned in the original press release is the revenue hit due to shutting down and restarting production. This has to be added to the estimate $700m cost of replacing the chips already out there (with manufacturers as well as consumers).
That revenue hit is only in this quarter but Intel don't expect the full year revenue to be affected too much! Jeez this company makes too much money!
$1 billion!
