n4d-highmem-64 by Google Cloud Platform

A memory-optimized x86_64 server configuration featuring sixty-four dedicated virtual CPUs and five hundred twelve gigabytes of system memory.

Google Cloud Platform n4d-highmem-64 is an x86_64 architecture server instance within the n4d family, configured with 64 dedicated vCPUs and 512.0 GB of RAM. This configuration provides a memory-to-core ratio of 8.0 GB per vCPU, making it suitable for memory-intensive workloads. The instance does not include local storage, integrated GPUs, or complimentary public IPv4 addresses, meaning all storage must be network-attached. Qualitatively, the dedicated CPU allocation and high memory density offer a specialized resource profile for applications requiring substantial memory capacity without the overhead of local physical disks. It is designed for workloads such as in-memory databases, large-scale caching, and memory-heavy data processing tasks.
