Titania AIPU

Don't Rebuild Your Datacenter. Upgrade It.

Rack-scale responsiveness in one air-cooled server.

Titania™ is designed for your data center, but built on the energy efficiency that Axelera AI is known for. A single air-cooled 4U Titania server is designed to match the per-user speed of a liquid-cooled Vera Rubin NVL72 rack on DeepSeek R1, in the racks you already own.¹

What is Titania?

Datacenter-class inference, in the racks you already own

Titania is the third generation of an architecture already proven on silicon. Two chiplets. 2.5 petaflops. 128 GB of LPDDR6. 400 watts. Together they make one package built for the models enterprises actually run: LLMs, mixture-of-experts, agents, vision-language models and video.

Each chiplet pairs 32 independently programmable AI cores with 32 RISC-V compute cores and 128 MB of shared SRAM, so Titania keeps pace with new model architectures instead of being locked to today’s. It supports MXFP4, FP4, MXFP8, FP8 and BF16 natively. On-chip 8K decode and 4K encode take video off the host CPU, so language, speech and vision run side by side on one system.

Eight Titania packages fit in one air-cooled 4U server with 1 TB of memory, enough to hold a 1.6-trillion-parameter model. Titania will ship as PCIe cards and OCP-compliant OAM modules, air- or liquid-cooled, from a single server to the AI factory. It runs on the same Voyager SDK customers use on Metis and Europa today.

Inside Titania: Built Layer by Layer

See how Titania comes together, from a single AI core to a datacenter-class System-in-Package. It builds on the architecture behind Metis and Europa and is designed to bring responsive, energy-efficient inference to the air-cooled racks you already own. It runs on the same Voyager SDK you use today.

Titania: Axelera internal simulations on an 8-card server (August 2026). Competitors: InferenceX data (September 2026). ISL/OSL 8k/1k, FP4. Power compared TDP vs TDP. Log scales.

Titania holds per-user speed, while GPUs trade it for total throughput. Rack-scale GPUs still lead at mega-batch throughput; Titania is built for responsive inference in the racks most operators already have.

Your Path from Europa to Titania

Deploy Europa

Europa is available now in Dell and Supermicro systems. Deploy it in your existing racks and start building your AI pipelines today.

Now

Build and Optimize

One Voyager SDK runs across Metis, Europa and Titania. AxeleraScript and Wingman help every developer build, tune and extend AI applications, without a dedicated ML team.

Then

Upgrade to Titania

Move your racks to Titania for datacenter-class memory and performance. Everything you built for Europa runs unchanged: no re-port, no rebuild.

2028

E4 Computer Engineering is widely renown as being leader on integrating the latest technology solutions. We are testing Metis from Axelera AI and are very impressed with its capabilities as well as of the support provided by the Voyager SDK. We firmly believe that the next solution, Europa, offers a leap in performance such that data centers will more efficiently support the needs of their customers and we are prepared to integrate this new solution into our ecosystem!
