This compares the the approximate production price of the 214 square millimeter "Willamette" die for the Pentium 4 as compared to the 145 square millimeter "Northwood" die for the Pentium 4 Intel will release tomorrow.
Xbit quotes a Mr Kevin Krewell as saying that the .18 micron die costs $100 in production costs, while the .13 micron die costs around $55 to produce.
As we noted many weeks back, Intel will introduce a 2.2GHz Pentium 4 tomorrow at $562, and if Mr Krewella is correct about La Intella"s cost, this is really a very satisfactory margin indeed for the chip giant.
