1998 research cohort / CPU
AMD · family
Candidate · no owner discrepancy decisionAMD-K6-2 processor with 3DNow! technology is recorded in the 1998 CPU research cohort under AMD. The current display name and classification are normalization proposals.
AMD addresses differentiated Windows computing and 3D imaging/sound performance
Intended users: Microsoft Windows PC users and desktop OEMs
Engineering response: AMD-K6-2 family adds 3DNow! instructions and Windows-oriented differentiation
AMD press release dated July 8 1998 filed as Form 8-K exhibit · lines 60-69
AMD explicitly states the problem and engineering response and names IBM, HP, and Fujitsu systems.
AMD's stated benefits are not independently measured here.
Comparable benchmark evidence has not been established for this record. Missing results do not imply poor performance.
The year above is a research-cohort label. Announcement, production, shipment and retail availability are distinct events.
Advanced Micro Devices Inc. is normalized to AMD; family-level display wording retains 3DNow! technology. The exact date belongs only to the family introduction.
Advanced Micro Devices Inc. · lines 52-69
AMD's filed exhibit states 'On May 28 we successfully introduced' the next-generation AMD-K6-2 processor family and reports more than 500,000 shipped in the quarter.
Launch speed-grade composition and orderable SKU boundaries are not established; manufacturer-controlled sources are not independent corroboration.
No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.
The AMD-K6-2 family and speed-grade records overlap intentionally but are different granularities; the family must not be counted as an additional speed-grade SKU.
Audit source · lines 52-69
AMD states a family introduction on May 28 and shipment volume but does not enumerate launch speed grades.
Follow-up: Retain the family as a family-level candidate; represent 350 and 400 as variants only when their quarter evidence is kept separate.
The current verification correctly avoids copying the family May 28 date onto the 350 or 400 variants; this remains a high-risk import guardrail rather than a present data error.
Audit source · lines 30-35; 48-75
AMD gives Q3 timing for 350 MHz while the family date is earlier; the family date does not establish the variant date.
Follow-up: Require typed event rows or explicit variant timing before normalization; retain quarter precision.
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.
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.
The mobile 300 MHz AMD-K6 record is not documented as an AMD-K6-2 speed variant. Its mobile AMD-K6 wording must remain separate from the AMD-K6-2 family and speed-grade hierarchy.
Audit source · lines 68-75
AMD states that it introduced a 300 MHz AMD-K6 processor for mobile applications during Q3 without calling it AMD-K6-2.
Follow-up: Do not assign AMD-K6-2 parentage or May family timing to the mobile AMD-K6 record; retain a separate family/category label pending product-identity evidence.
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.
