PRIMARY VENDOR SOURCE. 48 GB memory, 768 GB/s memory bandwidth, 240 GB/s I/O bandwidth, PCIe 5.0 x16, MTLink interconnect, 450 W max power, 266 x 112 x 39 mm. Lists supported precisions (FP64/FP32/TF32/FP16/BF16/INT8) but publishes NO throughput number for any of them. MTLink Bridge supports 2/4/8-card topologies; the 240 GB/s card-to-card figure equals the stated I/O bandwidth. Third-generation MUSA stack; MUSIFY tool claims automatic CUDA-to-MUSA source migration. Vendor claims 91% linear scaling on a 1000-card KUAE cluster. Shipped in MCCX D800 X1 dual-socket 8-GPU servers.
