in most cases. Compared with Klamath Pentium II processors, Deschutes Pentium II processors have increased speed, expanded system memory support, and other enhancements, but they still do not support greater than 2P SMP. Intel has also pre-announced some of the details of a second type of Deschutes - Compaq Armada 6500 | Deschutes Family Processor Technology - Page 5

Intel is launching several new sixth-generation processors - new 350 and 400 MHz versions of the
Pentium
II processor, and the Pentium
II Xeon
.
The Pentium II 350 and 400 MHz versions
were previously code-named Deschutes Slot 1 and the Pentium II Xeon was code-named Deschutes
Slot 2.
The Deschutes family of processors expands on the capabilities of previous Pentium II
processors and adds features such as a faster system bus, support for larger memory configurations,
and faster core frequencies. The new processors are targeted for two different markets.
Deschutes
Pentium II processors are designed to enhance price:performance for mainstream servers and
workstations.
The Pentium II Xeon processor is designed to provide outstanding performance for
high-end servers and workstations. As always, Compaq has engineered our servers and
workstations to provide customers with the optimal system performance from platforms based on
this new processor technology.
This technology brief provides a processor roadmap, a description of the new features, and relative
performance information for the new Deschutes Pentium II and Pentium II Xeon processors.
