x1e.16xlargeAWS Pricing, Specs & Benchmarks

The x1e family is a generation-1 high-memory line running on Intel Xeon (x86_64). x1e.16xlarge provides 64 vCPUs and 1952GB of RAM (a 1:31 vCPU-to-memory ratio), priced at $13.3440/hr On-Demand — about $9607.68 per month at 24×7 utilization.

High-memory instances are sized for SAP HANA, large in-memory databases, and other workloads where the dataset is enormous and disk I/O is unacceptable. If your workload doesn't match that profile — for example, if you're running a memory-bound app on a compute-optimized instance, or a CPU-pegged batch job on a burstable t-series — you'll likely pay for capacity you can't use or run into bottlenecks you didn't anticipate. The pages for sibling families (linked further down) cover those alternatives in detail.

In the AWS instance-naming convention, the digit after the series letter is the generation — higher is newer. This appears to be one of AWS's newer generations in the series, so for most fresh workloads it's a reasonable default within its category. The family suffix tells you about hardware variants: "e" = extended memory variant within the family.

Pricing varies by region (sometimes meaningfully — the gap between the cheapest and most expensive AWS region for the same SKU is often 15–30%). The regional pricing table further down shows where x1e.16xlarge is cheapest today, both On-Demand and Spot. Spot pricing for x1e.16xlarge is currently $1.8708/hr — roughly 86% off On-Demand — which makes the instance viable for fault-tolerant batch jobs, CI fleets, and any workload that can tolerate interruption with short notice.
