What it was

Intel Pentium II 266 MHz is recorded in the 1997 CPU research cohort under Intel. The current display name and classification are normalization proposals.

Source product name: Intel Pentium II processor 266 MHz
Source model number: Not established
Source manufacturer: Intel Corporation
Research scope: business desktop and workstation systems

Why it existed

manufacturer stated

Intel frames Pentium II as the next level of desktop computing performance

Intended users: desktop business and consumer PC users

Engineering response: Pentium II P6-family processor at 266 MHz with desktop system availability

Evidence and limits

Intel Delivers the Next Level of Computing with the New Pentium II Processor · launch and availability sections

Intel explicitly introduces the 266 MHz speed and same-day desktop system availability.

Marketing positioning; boxed/component outcome and regional scope are unknown.

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 introduction and system availability
Proposed timing: 1997-05-07 · exact precision
Assessment: proposed

Normalize the raw speed-grade wording to an Intel Pentium II model variant without inferring boxed availability.

Intel Delivers the Next Level of Computing with the New Pentium II Processor
Intel Corporation · launch paragraph and availability section
Intel names 266 MHz as a first-family Pentium II speed and states same-day system availability.

Open questions and review

Ordering part number and regional scope remain unknown.

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

scope error · resolved no change

Verified Intel desktop processor record; no material identity or timing discrepancy in frozen evidence.

Audit source · launch release

1997 Pentium II 266 identity and launch evidence retained.

Follow-up: No change; preserve desktop segment.

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

Intel introduced 266 MHz as part of the first Pentium II family launch; preserve same-day system availability and do not infer boxed timing.
