Intel recently released its newest chip, the Heracles chip, built from the ground up to handle fully homomorphic encryption (FHE) computing workloads. This revolutionary technology will radically change the pace and impact of encrypted computations. It dramatically increases return on investment, a huge leap forward in the industry. Heracles provides a performance leap by up to 5,000 times over leading Intel server CPUs. This groundbreaking technology, known as secure multi-party computation, has the potential to revolutionize secure data sharing and processing.
The Heracles chip was presented at the IEEE International Solid-State Circuits Conference (ISSCC). It features 64 compute cores in an eight-by-eight grid configuration, referred to as tile-pairs. By adopting state-of-the-art 3-nm FinFET technology and high bandwidth memory, Heracles delivers highly performant encrypted computing in large scale. As we observed back in November, that chip boasts an extraordinary frequency of 1.2 gigahertz. In addition, it sets a world record data transfer rate of 9.6 terabytes per second.
Groundbreaking Performance Metrics
Heracles’ performance metrics are widely considered to be extraordinary. In the most critical mathematical transformations necessary for FHE, Heracles completed these operations in only 39 microseconds. This timing is a remarkable 2,355-fold improvement compared to that same workload running on an Intel Xeon CPU at 3.5 GHz.
At ISSCC, Heracles demonstrated its significant capacity to accelerate FHE operations. It showed acceleration factors of between 1,074 and 5,547 times in seven major project areas. As highlighted by these figures, the chip’s ability to process complex computations required for secure data processing seamlessly is a key to its potential.

The chip is paired with 64 megabytes of cache memory, allowing it to handle tons of data at lightning speed. Heracles sports a liquid-cooled, 4,000-pound-class package. It features two 24-gigabyte high-bandwidth memory chips to help dissipate heat while tackling complex computing workloads.
Innovations in Architecture
Heracles architecture is optimized for the best performance in FHE computing. The on-chip 2D mesh network connects the tile-pairs through wide buses (512 bytes wide). This arrangement allows the cores to communicate in a highly efficient manner, distributing the data transport and processing load.
Sanu Mathew, one of the masterminds behind the creation of Heracles, laid out why this breakthrough was so important.
“Heracles is the first hardware that works at scale,” he stated, highlighting the chip’s unique capability to manage high-demand applications effectively.
The synergy between cutting-edge technology and architectural design allows Heracles to host next-generation applications that need massive amounts of computational resources. As more industries adopt secure, privacy-preserving data processing solutions, this chip is striking while the iron is hot.
Implications for Future Applications
Heracles’ launch could be a watershed moment for all applications that depend on homomorphic encryption. The chip’s advanced abilities promise more profound machine-learning processes, like neural networks and semantic search. Kurt Rohloff noted the shift towards hardware solutions in these areas:
“Where you start to need hardware is emerging applications around deeper machine-learning oriented operations like neural net, LLMs, or semantic search.”
Intel’s progress with Heracles should have an impact on smaller models. John Barrus remarked on this potential:
“There are a lot of smaller models that, even with FHE’s data expansion, will run just fine on accelerated hardware.”
Intel’s Heracles chip represents huge gains in processing speed and efficiency. With their availability, public sector, private sector, and academic leaders can accelerate the wider adoption of encrypted computing, increasing data security while maintaining human performance at scale.
