Intel's Heracles chip computes fully-encrypted data without decrypting it — chip is 1,074 to 5,547 times faster than a 24-core Intel Xeon in FHE math operations

Intel has revealed an 8192-way SIMD compute engine for fully homomorphic encryption math called Heracles. By operating directly on encrypted data, it has the potential to eliminate entire classes of attacks under some workloads.
