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.

Summary of Contents for Compaq Armada 6500 - Notebook PC

  • Page 1 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.
  • Page 2 BUSINESS INFORMATION), EVEN IF COMPAQ HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. The limited warranties for Compaq products are exclusively set forth in the documentation accompanying such products. Nothing herein should be construed as constituting a further or additional warranty.
  • Page 3 (cont.) N T R O D U C T I O N Intel has announced new 350 MHz and 400 MHz versions of the Pentium II processor. This processor was previously known by the code name Deschutes Slot 1. In addition, Intel has pre- announced details of the Pentium II Xeon processor, previously called Deschutes Slot 2.
  • Page 4 (cont.) multiprocessing (SMP) configurations, a maximum of 512K L2 cache, and have a 512-MB memory cacheability limit. Deschutes is the code name for a new family of processors that have increased bus speed and other enhancements. Intel is releasing several new Deschutes processors in 1998. Intel has announced the first of the new Deschutes-based processors 350 MHz and 400 MHz Pentium II processors.
  • Page 5 (cont.) Pentium II / IA32 Architecture Both the Deschutes Pentium II and Pentium II Xeon processors use the same basic architecture as previous Pentium II processors. The Deschutes family continues the same IA32 technology line; it is fully software compatible with all previous Pentium Pro and Pentium II processors. Like the Pentium Pro and Pentium II, the Deschutes family uses Dynamic Execution techniques and a dual independent bus structure.
  • Page 6 (cont.) I I X E N T I U M E O N In addition to the features of the Deschutes Pentium II processor such as 100-MHz GTL+ and MMX, the Pentium II Xeon processor will have these features: Processor speeds starting at 400 MHz and expected to increase to 450 MHz and beyond 512-KB, 1-MB, and 2-MB L2 cache configurations Full-speed L2 cache bus Slot 2 cartridge...
  • Page 7 15.8 12.4 Over the years, Compaq has developed tools to make accurate predictions of processor and system performance even before the hardware designs are complete. Although the Pentium II Xeon processor has not been formally announced by Intel, Compaq engineers have used this expertise to model the performance of Pentium II Xeon systems.
  • Page 8 (cont.) 400 MHz/2M Pentium II Xeon vs. 200 MHz/1M PPro with 4G PPro Pentium II Xeon Figure 2. Projected performance of a 400-MHz Pentium II Xeon processor with 2-MB L2 cache vs a 200- MHZ Pentium Pro with a 1-MB L2 cache. (Higher = better) O N C L U S I O N The new Deschutes Pentium II and Pentium II Xeon processors, scheduled to announce in mid- 1998, are an extension of the Pentium II family, and keep the same IA32 architecture used in...
