Microsoft Reportedly Working on Its Own “Athena” AI Chip

Microsoft Athena is a proprietary AI chip that will support natural language models, but it won’t arrive until 2024.


Reports of developing its own AI chip have been circling for some time. Now, The Information reports that Microsoft is working on the AI chip, which is developing under the codename “Athena”. The processor will compete with 's Hopper H100 GPU, which is also used by Microsoft for its Azure cloud platform.

The Athena chip is expected to support large-scale natural language processing (NLP) applications, such as conversational agents and text summarization. Microsoft wants its AI CPU to reduce how much the company relies on Nvidia and also deliver a more custom experience to users.

Athena is not expected to be announced until 2024. Not much is known about the chip, so it is hard to compare it with other AI chips that are already available or announced. However, based on the information, here is what we know so far:

  • Microsoft Athena will be built on the TSMC 5-nanometer process. Nvidia's Hopper H100 GPU and AMD's EPYC Milan chipsets both also operate on this platform.
  • Athena will fully support large-scale natural language processing (NLP) apps, such as conversational . While other AI chips can do this, Microsoft's processor will have higher customization and better integration with the company's own cloud services and software.
  • Microsoft's AI chip will be a rival to other CPUs, such as 's TPU, Meta's GROK, and Amazon's Trainium.

TSMC to Be the Sole Athena Manufacturer?

Earlier this year, I reported on Microsoft turning to TSMC (Taiwan Semiconductor Manufacturing Company) to build the Athena chip, using the company's CoWoS platform.

TSMC is the biggest contract chip manufacturer in the world. Its Chip-on-Wafer-on-Substrate (CoWoS) chipset is a platform that is designed for high-performance computing, such as . The company is also opening a new US plant in 2024 that will supply chipsets to Apple. A long-standing customer, makes up 25% of TSMC's revenue each year.

If Microsoft's current push in AI continues, the company may become another major revenue driver for TSMC.

Tip of the day: The Windows Clipboard history feature provides the functionality across device, space, and time, letting you copy on one computer and paste the text days later on a different PC. All of it is possible via the Windows 10 clipboard manager, which lets you view, delete, pin, and clear clipboard history at will.

In our tutorial we show you how to enable the feature, clear clipboard history, and enable/disable clipboard sync to meet your preferences. You can also create a clear clipboard shortcut for quick removal of stored content.
