CDC 7600: Measurement, Relationship with the CDC 6600 & Design
The CDC 7600 was designed by Seymour Cray to be the successor to the CDC 6600, extending Control Data's dominance of the supercomputer field into the 1970s. The 7600 ran at 36.4 MHz (27.5 ns clock cycle) and had a 65 Kword primary memory (with a 60-bit word size) using magnetic core and variable-size (up to 512 Kword) secondary memory (depending on…

Important terminology
Frequent words and multi-word phrases across the lead, headings, infobox and body. Useful for terminology coverage.
Use these terms to understand the vocabulary surrounding the topic, not as a checklist for keyword stuffing.
Relationships are represented as Subject → Predicate → Object triples. Confidence describes extraction strength, not the real-world importance of a relationship; lower-confidence rows may be contextual rather than explicit.
TTTA extracted 80 structured relationships around CDC 7600. Examples in this analysis include CDC 7600 → CPU → 60-bit processor @ 36 MHz and CDC 7600 → Designer → Seymour Cray. The table shows each extracted connection, where it came from and its confidence.

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For CDC 7600, one of the stronger structural bridges in this analysis connects CDC 7600 with Relationship with the CDC 6600. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
