The Big Island GPGPU developed by Tianshu Zhixin is produced by TSMC on the 7 nm nodes with 2.5D CoWoS packaging. It integrates 24 billion transistors, is rated for 300 W TGP and the board includes 32 GB of HBM2 VRAM plus a single 8-pin connector. Its performance is comparable to AMD's Instinct MI100.

Not clear in the slides but later clarified that the FP32 TFLOPs figure includes matrix operations. These are great for certain machine learning applications but less useful for rendering. In a similar hypothetical scenario the MI100 is up to 46.1 FP32 TFLOPs.
