1. Architecture and ISA
- “It's Arm based, although they barely mention that.” – rwmj
- “It is a custom Armv9.3‑A design … double‑width execution units for SVE2 … ISA extensions for AI/ML (e.g. FP8 inference).” – adrian_b
- “No it is not at all Neoverse V2 … it has enhanced SVE2 … Fujitsu did not mention SME.” – adrian_b
2. Manufacturing / Sovereignty claims
- “Japan‑developed 2nm 3D‑stacked CPU … server integrated, developed, and manufactured in Japan.” – bradquoted from the article (bradyd)
- “The core die is made with TSMC‑N2P, while the SRAM die and peripheral die are made with TSMC‑N5.” – adrian_b
- “They are relying on TSMC for the first batch and are planning to move production to JASM once that’s ready.” – tremon
3. Performance and suitability for AI/HPC
- “Their CPUs are faster at inference than many GPUs … 144 cores and wide memory interface … 4.3‑6 TFLOPS.” – adrian_b
- “It looks … an AI‑optimized HPC CPU … but not particularly well suited for transformer‑based neural nets.” – imtringued
- “844 GB/s memory bandwidth … comparable to a modern (although not top‑end) GPU, good for HPC & AI workloads.” – qsbuilder
4. Fujitsu’s corporate reputation and history
- “Fujitsu is basically the Japanese IBM.” – sam1714
- “Fujitsu’s SPARC implementations were much faster than Sun’s … dominated the CAD/EDA market 1995‑2005.” – adrian_b
- “The two made‑in‑Japan Fujitsu laptops I had … fans running continuously at max speed … worst pieces of electronics I have ever used.” – 10729287
- “Their software is so poor that it caused probably the biggest miscarriage of justice in history.” – pipes (referring to the British Post Office scandal)
