i8ge.3xlargeAWS Pricing, Specs & Benchmarks

The i8ge family is a generation-8 storage-optimized (NVMe SSD) line running on AWS Graviton (ARM64) — AWS-designed processors built for price/performance. i8ge.3xlarge provides 12 vCPUs and 96GB of RAM (a 1:8 vCPU-to-memory ratio), priced at $1.4238/hr On-Demand — about $1025.14 per month at 24×7 utilization. In Sysbench CPU benchmarks it scores 3334 single-core and 39849 multi-core.

Storage-optimized (NVMe SSD) instances are sized for NoSQL databases (Cassandra, ScyllaDB), search engines (Elasticsearch), transactional databases needing very low storage latency, and large log-ingestion pipelines. 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 i8ge.3xlarge is cheapest today, both On-Demand and Spot. Spot pricing for i8ge.3xlarge is currently $0.2425/hr — roughly 83% 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.
