Inferentia2
A dedicated AI inference acceleration chip developed by AWS, optimized for low-latency, high-throughput deep learning inference.
Timeline (last 90 days)
The MCP server demo includes six inference backends: Amazon Bedrock, a SageMaker endpoint, vLLM on EC2 g6, an inference service on g5g, and Gemma 4 models on Inferentia2 (inf2) and Trainium (trn1).
In this article's scenario, the inf2 instance passed its health check only about 20.4 minutes after launch, with logs showing "READY in 473.8s", due to the time taken by model compilation and NeuronCore loading.
Inferentia2 and Trainium have 2.0 to 2.7 times the memory bandwidth of NVIDIA L4, but their decode speed is only 0.28 times that of L4.
Inferentia2 and Trainium have 2×16 GiB of memory, with each NeuronCore exclusively owning 16 GiB, so the model must be split across the two cores or fit into 16 GiB, which is a hard constraint for the E2B model where the embedding table accounts for the bulk.
Google TPU v5e, Groq LPU, and AWS Inferentia2 are new chips specifically optimized for inference.
