Lenovo's ThinkCentre X Ultra puts 128GB of unified memory in a 1.6-liter box, and you can cluster four of them together

Lenovo announced the ThinkCentre X Ultra at its Innovation World event during IFA 2026: a 1.6-liter desktop built around AMD's Ryzen AI Max+ PRO 495 with up to 128GB of unified memory, starting at $3,699, shipping in November 2026.

The company calls this offering a new class of desktop for agentic AI, and it can be configured to cluster up to four systems, effectively pooling processing power and memory to run large AI models locally.

The added compute and memory capacity lets users run longer context windows and multi-agent workflows without turning to cloud-hosted alternatives, while keeping data localized.

The Ryzen AI Max+ PRO 495 is the flagship of AMD's Gorgon Halo refresh, pairing 16 Zen 5 cores with a 40-compute-unit Radeon 8065S integrated GPU and an NPU rated at roughly 55 TOPS. Its defining trait is the shared memory pool: the CPU and GPU address the same LPDDR5X memory under the hood, so it can effectively hold and run models that a discrete, consumer-grade GPU with 24GB or 32GB of VRAM cannot.
