ISSCC 2026: Rebellions details industry's first quad-chiplet AI solution with UCIe interconnects — claims Rebel100 AI accelerator equals the power of Nvidia H200 with lower power envelope

Rebellions introduced the Rebel 100 AI accelerator at ISSCC 2026, utilizing UCIe interconnects to stitch together four chiplets, offering performance comparable to Nvidia's H200 but with lower power consumption. The quad-chiplet design maximizes die yield and performance for large language model inference, featuring a mesh topology interconnect and 12Hi HBM3E memory stacks. The Rebel 100 connects to hosts via PCIe 5.x interfaces and can deliver 2 FP8 PFLOPS at 600W, positioning it as a foundational unit for supporting trillion-parameter models. Rebellions implemented a 2D network-on-chip, hardware staggering technique for power delivery, and proprietary data movement engines to optimize performance and reliability in the multi-chiplet design.
