## Feature Feature **Generally available**: The network- and memory-optimized[M4N machine series](https://cloud.google.com/compute/docs/network-optimized-machines#m4n%5Fseries) is generally available. Powered by 5th generation Intel Xeon Scalable processors (Emerald Rapids), M4N instances are purpose-built for network and block storage-intensive workloads such as: * High-performance vector databases * Retrieval-augmented generation (RAG) data layers * Massive in-memory context caching * Real-time semantic search The M4N machine series delivers the highest I/O performance available in Compute Engine, supporting up to 400 Gbps of network bandwidth. M4N also offers leading block storage performance with Hyperdisk Extreme that scales up to 25 GiB/s of bandwidth and 1M IOPS. M4N instances are available in predefined machine shapes, ranging in size from 16 to 224 vCPUs and up to 5,952 GB of DDR5 memory.
