Iluvatar CoreX BI-V100 Tiangai 100
Overview
The Iluvatar CoreX (天数智芯) BI-V100, branded Tiangai 100 (天垓100), is described as China's first domestic 7nm general-purpose GPGPU, launched in 2021 as a full-height full-length dual-slot PCIe Gen4 card with 2.5D CoWoS packaging (~24B transistors). The vendor headline is 147 TFLOPS FP16/BF16 (dense), with 32 GB HBM2 at 1.2 TB/s in a 250W board. FP32, TF32 and INT8 peaks are not reliably published and are omitted rather than guessed. Note: a widely-circulated "TPP ~2,352" figure for this chip is the US BIS export composite (TOPS x bit-length), NOT a TFLOPS throughput value, and is intentionally not stored.
