End of Interactive Support
Intel is announcing the end of interactive support for the Pentium®
II Xeon® processors. See the End of Interactive Support Announcement for details.
The Pentium®
II Xeon®
processor is available at 400 and 450 MHz in a new family
of branded Intel processors specifically designed to meet
the demands of mid-range and higher servers and workstations.
To meet these demands, the Pentium II
Xeon processor combines several premium characteristics: the
architectural compatibility of previous Intel microprocessor
generations; the Dynamic Execution and Dual Independent Bus
architecture of the P6 microarchitecture found in the Pentium®
II processor;
and several new features designed to make this processor the
right choice for powerful workstations, advanced server management
and business-critical applications.
The Pentium II
Xeon processor at 400 MHz is available in 512K and 1 MB L2
cache options, and the Pentium II
Xeon processor at 450 MHz is available in 512K, 1 MB, and
2 MB L2 cache options.
The Pentium II
Xeon processor improves upon the Pentium Pro processor by
adding MMX™ technology for 3-D compute-intensive applications,
and by utilizing the S.E.C. (Single Edge Contact) cartridge
package technology first introduced on the Pentium II
processor.
Like the Pentium Pro
processor, level 2 cache communication occurs at the full
processor core speed.
A significant feature
of the Pentium II
Xeon processor, from a system perspective, is the built-in
direct multiprocessing support. The Pentium II
Xeon processor supports both uniprocessor and multiprocessor
implementations with up to four processors on each local processor
bus, or system bus.
The Pentium II
Xeon processor system bus operates using GTL+ signaling levels
with a new type of buffer utilizing active negation and multiple
termination. This new bus logic is called Assisted Gunning
Transistor Logic, or AGTL+.
Product Overview
- Power and performance
for mid-range and higher servers and workstations.
- Available at operating
frequencies of 450 MHz or 400 MHz
- 32KB (16KB data
/16KB instruction) non-blocking, Level One (L1) cache provides
fast access to heavily used data
- Dual Independent
Bus (D.I.B.) architecture increases performance and provides
more data to the processor core
- 100 MHz system bus
speeds data transfer between the processor and the system
- 400 MHz offers
1 MB and 512 KB L2 cache options. 450 MHz offers 2 MB, 1
MB, and 512 KB L2 cache options.
- Level 2 cache bus
operating at same speed as processor core provides new level
of peak bandwidth to the processor
- Cacheable address
space up to 64GB
- "Glueless" multiprocessing
support for up to four processors
- Supports 8-way
and beyond systems through other clustering technologies
- Intel® Extended
Server Memory Architecture--expanded 36-bit memory support
which allows operating systems and applications to utilize
memory greater than 4 Gbytes
- Thermal sensor
allows system to actively manage thermal conditions
- Error Checking
and Correction (ECC) to maintain the integrity of mission-critical
data
- Functional Redundancy
Checking (FRC) to confirm processing integrity
- System Management
Bus (SMBus) for efficient communications between the processor
thermal sensor, processor-specific PIROM, OEM-writable EEPROM
and the rest of the system
