# Huawei-linked LineShine supercomputer crams 2.45 million Arm cores into one enormous AI cluster.

*semiconductor · news · 2026-05-19 · TechRadar*

## Key points

- China's LineShine supercomputer achieves 1.54 exaflops AI training using only CPUs, not GPUs.
- The cluster contains 2.45 million Armv9 cores across 20,480 nodes with Huawei-linked LX2 processors.
- Each LX2 processor integrates 32GB HBM and up to 256GB DDR5, providing very high memory bandwidth.
- LineShine's CPU-only design avoids CPU-GPU data transfer bottlenecks but sacrifices AI power efficiency.
- China's shift to CPU-only AI systems is driven largely by US GPU export bans, not technical advantage.

**Companies:** Huawei
**Countries:** China
