Last week, Intel officially introduced a breakthrough in secure computing called confidential computing. Just this week, they showed off their latest chip–Heracles — at the International Solid-State Circuits Conference (ISSCC). This new chip represents an exciting application of a fully homomorphic encryption (FHE)-encrypted language model called BERT. It holds the potential to significantly improve the way we analyze encrypted data. The launch of Heracles is another step forward in Intel’s long-term strategy to be a leader in secure computing.
Heracles has a virtual monopoly on the FHE research chip landscape. In fact, it’s currently about 20 times larger than its closest competitors. Heracles operates on Intel’s next-generation 3-nanometer FinFET technology node. It addresses the increasing demand for high-performance data processing in diverse, mission-critical applications. The chip is composed of 64 of these compute cores, or tile-pairs, organized in an eight-by-eight grid. As a result, it runs at a blistering 1.2 gigahertz frequency.
At hands-on demos, Heracles wowed attendees by showcasing the system’s astounding ability to transform FHE computing tasks and perform them at never-before-seen speeds. It performed essential mathematical transformations faster than 39 microseconds. This accomplishment represented an incredible 2,355-fold performance improvement compared to an Intel Xeon CPU clocked at 3.5 GHz. On top of that, Heracles showed performance levels that were orders of magnitude— as much as 5,000-fold— faster than a state-of-the-art Intel server CPU on the market.
Advanced Architecture and Performance
Heracles was built with ease of use and efficient data processing in mind. It employs an on-chip 2D mesh network that connects the tile-pairs with busses as wide as 512 bytes. This design increases the speed of data movement and processing. To that end Heracles has the capacity to handle a magnificent 9.6 terabits of data per second.
Heracles has 64 MB of cache memory. It packs two high-bandwidth memory chips, each providing 24 gigabytes, with high capacity resources sating the most resource-hungry applications. The chip features advanced high-speed processing and memory capabilities. This formidable union gives it excellent power to control encrypted data, which makes this tool really handy to protect advanced apps, where confidentiality is critically needed.
Intel’s use of liquid cooling technology contributes to Heracles’ performance. It ensures peak performance of the controller, maintaining optimum operating temperatures. Moreover, it guarantees high-performance computing, in the matters of efficient and frantically paced environments importance.

Implications for Future Applications
Heracles is more than a performance metric though. It’s a huge step in the right direction for secure computing at large. Organizations are using encrypted data more than ever before to power their sensitive operations. This increase in dependence makes the ability to process and act very quickly absolutely essential.
Kurt Rohloff emphasized the importance of this advancement, remarking that “where you start to need hardware is emerging applications around deeper machine-learning oriented operations like neural net, LLMs, or semantic search.” This underscores the increasing need for more specialized hardware that can efficiently process these complex algorithms while helping to safeguard sensitive data.
John Barrus added that “there are a lot of smaller models that, even with FHE’s data expansion, will run just fine on accelerated hardware.” This suggests that even less complex applications can benefit from the capabilities offered by Heracles, potentially broadening its adoption across various sectors.
“When Intel starts talking about scale, that usually carries quite a bit of weight.” – Kurt Rohloff
A New Era in Secure Computing
The demonstration of Heracles at ISSCC showcased its technical specifications and illustrated its potential impact on the future of computing. Ro Cammarota stated, “We have proven and delivered everything that we promised,” reinforcing Intel’s commitment to innovation and excellence in technology.
Sanu Mathew compared this moment to the dawn of microprocessors, declaring, “This is like the first microprocessor… the start of a whole journey.” This short definition captures the brilliance of Heracles, as it is only the beginning of what’s to come in the age of secure and confidential computing.
Industries are anxious to take advantage of new advancements in artificial intelligence and machine learning. Here Heracles emerges again as a highly important solution to support ongoing data integrity and security. Specifically, it executes FHE operations at record speeds. These abilities combined make it a game-changer for organizations leading the charge against the growing data privacy and security challenges.
