Enflame Yunsui T20
Overview
The Enflame (燧原科技) Yunsui T20 (云燧 T20) is a training accelerator built on Enflame's second-generation DTU 2.0 (邃思2.0) GCU architecture on 12nm, launched July 2021 as a full-height full-length PCIe card. Stored figures are the de-rated 300W T20-card dense peaks: 33.6 TFLOPS FP32, 134.4 TFLOPS TF32/FP16/BF16, and 268.8 TOPS INT8 (the full 邃思2.0 chip / 400W T21 OAM module runs higher at 40/160/320). Memory is 32 GB HBM2E with GCU-LARE scale-out at 300 GB/s. Memory bandwidth is left NULL: the widely-cited 1.8 TB/s figure is the full chip / 64GB-SKU spec, and the 300W/32GB T20 card's HBM bandwidth was not separately confirmed.
