Intel's Heracles Chip Blasts Encryption Speeds by 5,000x
Intel revealed a dedicated chip that accelerates fully homomorphic encryption tasks 5,000 times faster than its best server processors.
Intel pulled the curtain back on Heracles, a purpose-built chip designed to supercharge fully homomorphic encryption — the holy grail of processing encrypted data without ever decrypting it.
The numbers are staggering. Intel claims Heracles delivers up to 5,000x faster performance on FHE tasks compared to the company's own top-tier server CPUs. That's not a typo. Five thousand times.
The chip was unveiled at ISSCC in February, the premier conference for cutting-edge semiconductor research.
Why it matters: Fully homomorphic encryption has long been considered too slow for practical use. It lets you compute on encrypted data directly — meaning sensitive information never needs to be exposed. A 5,000-fold speedup could finally push FHE from academic curiosity into real-world deployment.
Dedicated silicon for privacy-preserving computation is a bet Intel clearly wants to own.
