The Intel Nervana NNP-I 1150 (Spring Hill, SRK1U) is an M.2 Key M form factor inference accelerator. It integrates two Intel Sunny Cove cores and twelve Inference Compute Engines (ICEs) on a 10nm SoC. The chip includes 24 MB of shared LLC, 3 MB of tightly coupled memory (256 KB per ICE), and 48 MB of deep SRAM (4 MB per ICE). It supports LPDDR4x-4266 memory with 16 or 32 GB capacity and 67.2 GB/s bandwidth.
The card connects via M.2 PCIe Gen3 x4 and has a typical TDP of 12W. It is designed to accelerate low-latency AI inference workloads and operates independently with an embedded Linux-based OS loaded by the host driver at runtime.
