Intel just introduced a revolutionary new chip called Heracles. This pioneering chip, the first of its kind created and optimized for FHE computing in general, was presented at IEEE International Solid-State Circuits Conference (ISSCC) held at San Francisco. This innovative technology promises to revolutionize data security through encrypted computations, boasting remarkable speed and efficiency improvements over existing hardware.
Heracles provides transformative performance improvements for computing tasks performed on fully homomorphic encrypted (FHE) data, with speedups of up to 5,000 times versus Intel’s fastest server CPUs. The chip boasts 64 full-fledged compute cores, in a highly efficient eight-by-eight-grid. Advanced 3-nanometer FinFET technology paired with high-bandwidth memory supports the most advanced workloads and highest performance. With its versatility and robust architecture, Heracles has the potential to be the new standard for processing encrypted data.
Key Features of Heracles
Heracles is characterized by a number of extraordinary specifications, which influence on its massive performance. It is no larger than 10 mm2. That size is roughly 20 times larger than other research chips that have been developed targeting the FHE. The chip’s architecture features an on-chip 2D mesh network. This expansive network ties all the tile pairs together with 512-byte wide buses which allows for higher performance communication between all the cores.
The chip runs at 1.2 gigahertz of clock speed and has 64 megabytes of cache memory. It performs FHE’s necessary mathematical transformation in just 39 microseconds. This represents a remarkable 2,355-fold advance relative to an Intel Xeon CPU running at a clock speed of 3.5 GHz. With this degree of efficiency, Heracles makes a powerful player in the space of confidential computing.

Heracles has an amazing potential to analyze data at a rate of 9.6 terabyte per second. It does this by artfully hopping between tile-pair to tile-pair. Heracles proved its steal-with-a-killer-robot prowess in live kill demos at ISSCC. It was 1,074–5,547 times faster than competing chips for seven important tasks.
Impact on Future Applications
Heracles was very accomplished, as a encrypted computation. This development has been even more pronounced in the sectors of cloud computing and AI (artificial intelligence) infrastructure. Experts believe that the chip will facilitate the development of emerging applications requiring robust data security, such as advanced machine learning operations and semantic search technologies.
Kurt Rohloff highlighted the importance of this development, stating, “When Intel starts talking about scale, that usually carries quite a bit of weight.” He argued that the more manageable models are, the easier and faster they are to run on accelerated hardware. This can be done even despite FHE’s built-in data inflation. This is a strong indication that Heracles could make possible a wider array of applications that depend on processing encrypted data.
Sanu Mathew further emphasized the importance of optimizing data movement inside Heracles. He remarked, “It’s all about balancing the movement of data with the crunching of numbers.” This delicate equilibrium is central to optimizing the chip’s performance, especially as it takes on more advanced computation heavy-lifting.

We are pleased to see Intel’s strong vision and commitment to advancing the state of FHE technology. They’ve claimed Heracles as the world’s first commercially viable FHE accelerator. This aggressive positioning tells us that Intel wants to be the ones that allow you to do practical, encrypted computations at the speeds you demand from real world applications.
The Road Ahead for FHE Computing
As Heracles strides onto the world stage, its implication on data privacy and security are substantial. The chip now has the capacity to perform encrypted but still meaningful computations at unbelievable speeds. This breakthrough unlocks the potential for more secure cloud offerings and next-gen AI capabilities. Now organizations have the ability to compute on sensitive information without ever needing to expose it to potential vulnerabilities while in use.
And with the acceleration Heracles gave them, that creates opportunities for far more applications,” commented John Barrus. He stated, “There are a lot of smaller models that, even with FHE’s data expansion, will run just fine on accelerated hardware.” Industries that focus and deal in sensitive data have been doing pretty quickly. They’ll be doing it more and more with FHE solutions powered by Intel’s brilliant technology.
Heracles further responds to the increasing imperative for security within ML operations. Organizations are beginning to take advantage of more complex machine learning approaches such as neural networks and large language models (LLMs). This change only exacerbates the need for strong hardware solutions that work. Rohloff remarked on this trend, saying, “Where you start to need hardware is emerging applications around deeper machine-learning oriented operations.”
