What it was

Intel Pentium II Xeon processor 400 MHz is recorded in the 1998 CPU research cohort under Intel. The current display name and classification are normalization proposals.

Why it existed

manufacturer stated

Intel targets demanding enterprise and technical workloads requiring scalability and larger/faster cache

Intended users: servers and workstations

Engineering response: 400 MHz Pentium II Xeon with 512 KB or 1 MB L2 options; four/eight-way scalability; 100 MHz bus

Evidence and limits

Intel Introduces New Pentium II Xeon Processor to Achieve Unmatched Performance Levels for Servers and Workstations · lines 6-9,13-26

Intel explicitly names Internet services, data warehousing, digital content creation, EDA, multiprocessing, and cache options.

Positioning and benchmark references are Intel-supplied; cache options make one-row comparison problematic.

What difference it made

Comparable benchmark evidence has not been established for this record. Missing results do not imply poor performance.

Release evidence

The year above is a research-cohort label. Announcement, production, shipment and retail availability are distinct events.

Proposed event
product family introduction and component availability

Assessment
proposed

Manufacturer name is shortened from Intel Corporation; the 400 MHz wording is preserved. The exact date applies to family introduction and component availability, not later boxed availability.

Open questions and review

Whether 512 KB and 1 MB L2 cache options are separate SKU records; exact boxed availability date; whether this candidate should later be family or variant granularity.

No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.

family variant overlap · follow up

The Xeon 400 MHz record hides at least two cache configurations that may be separately orderable variants; treating it as one fully specified product risks undercounting or conflating SKUs.

Audit source · lines 13-26

Intel describes 512 KB and 1 MB L2 options with separate prices and channel timing.

Follow-up: Resolve product-versus-configuration granularity and retain cache evidence before canonical import.

family variant overlap · follow up

The Xeon 400 MHz record has a cache-configuration boundary: Intel names 512 KB and 1 MB L2 options with different prices and later boxed-channel timing. A single record must not imply a fully resolved single SKU.

Audit source · lines 13-26

Intel gives separate cache-option pricing and distinguishes June 29 component availability from later boxed availability.

Follow-up: Keep the record at unresolved model-variant granularity until human review chooses whether cache configurations require separate candidate or assertion treatment.

Original intake sources

These notes preserve the state at intake. Later verification is shown under Release evidence above; an original note saying verification had not occurred is not the current assessment.

Original research note

At least 512 KB and 1 MB L2 cache options are named; this may require separate SKU-level records
