What it was

AMD-K6-2 processor 366 MHz is recorded in the 1998 CPU research cohort under AMD. The current display name and classification are normalization proposals.

Source product name
366MHz AMD-K6-2 processor
Source model number
Not established
Source manufacturer
Advanced Micro Devices Inc.
Research scope
Microsoft Windows compatible PCs; North American retail evidence is reported for the family

Why it existed

manufacturer stated

AMD positions higher clock versions as part of a speed roadmap and customer-demand response

Intended users: Microsoft Windows PC customers and OEMs

Engineering response: 366 MHz AMD-K6-2 with 3DNow! technology

Evidence and limits

AMD press release dated January 13 1999 filed as Form 8-K exhibit · lines 62-69

Filed release states 366 MHz was introduced and shipped in volume during Q4 as part of speed-roadmap execution.

Retrospective and lacks a specific problem statement for 366 MHz.

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
variant introduction and volume shipments
Proposed timing
1998-Q4 · quarter precision
Assessment
proposed

Quarter-precision variant event is supported and kept separate from the family date.

Open questions and review

Exact day/month, first shipment, package/orderable identity.

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

family variant overlap · follow up

The AMD-K6-2 family and four speed-grade records intentionally overlap across granularities; the family must not be counted as a fifth speed-grade record or used to infer an exhaustive launch-SKU list.

Audit source · lines 52-69

AMD states a May 28 family introduction and quarterly shipment totals but does not enumerate the family launch speed grades.

Follow-up: Retain the family as a family-level candidate and each speed grade only as separately evidenced variants; do not use the group as a count of five comparable SKU claims.

date inheritance · resolved no change

The exact May 28 AMD-K6-2 family date cannot be inherited by any speed-grade candidate. The 350 MHz variant is Q3 evidence and the 366 MHz 380 MHz and 400 MHz variants are Q4 evidence only.

Audit source · lines 27-32 and 62-69

AMD's Q4 filing identifies 366 MHz 380 MHz and 400 MHz versions as introduced and shipped in volume during Q4; it does not supply an exact date.

Follow-up: Keep the family exact date and each speed-grade interval separately typed; reject any normalization that converts quarter evidence to day or month precision.

evidence gap · follow up

All four AMD-K6-2 speed-grade timing claims are manufacturer-controlled retrospective quarter statements. They support bounded 1998 intervals but not exact first-shipment dates or orderable identities.

Audit source · lines 30-35 and 48-75

The Q3 filing supports the 350 MHz interval while the Q4 filing supports 366 MHz 380 MHz and 400 MHz intervals; neither resolves exact dates.

Follow-up: Retain quarter precision and flag independent contemporary or channel evidence as optional follow-up rather than filling missing dates.

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

Typed events: AMD's January 13, 1999 filed release retrospectively states that 366 MHz versions were introduced and shipped in volume during Q4 1998. Date precision is quarter; exact day/month and first shipment are unknown.
