New roadmap from Intel
An unofficial roadmap from Intel contains the following information regarding future CPUs: According to this, a Pentium 4 with 2.2 GHz is to appear this year. So far, only a maximum of 2 GHz has been calculated. The 2.2 GHz variant is then based on the new Northwood core and is manufactured using 0.13 µm technology. The 2.2 GHz version will be the first CPU with the new Northwood core.
The current Willmatte- Kern will still reach the 2 GHz mark and will soon be switched to socket 478, which Northwood will then also use. The Northwood's cache is twice as big as that of the Willmatte and should have a positive effect on the Pentium 4's performance, as the insufficiently small cache was often criticized. In the second quarter of 2002 a Pentium 4 with 2.4 GHz will follow, which is also based on the Northwood core. The Willmatte with 2 GHz will be available for around US $ 562 in the third quarter. The Tualatin, on the other hand, should only reach a maximum of 1266 MHz and be available in three versions. On the one hand with 1133 MHz, on the other hand with 1200 MHz and third with 1266 MHz. It will be available in the second or third quarter. From 2002 the Tualatin will replace the current Celeron. Nevertheless, it should not reach more than 1266 MHz. The Tualatin is well suited as a low-cost CPU because it is manufactured using 0.13 µm technology and the chip can be produced very cheaply. It should be slightly superior to the Duron. Maybe Intel will decide not to set the Tualatin at 1266 MHz.
