NNP-T 1300 is a training neural processor designed by Intel Nervana and introduced in late 2019. Fabricated on TSMC 16 nm process based on the Spring Crest microarchitecture, the NNP-T 1300 has 22 TPCs along with 55 MiB of scratchpad memory and operates at up to 950 MHz. This chip comes in a PCIe 4.0 accelerator card form factor and incorporates 32 GiB of HBM2 memory. This NPU exposes 16 inter-chip links for scale-out capabilities.
