Per hour on Windows, in each type's cheapest region. Typical spot: per pricing run of the last 7 days, the cheapest zone's spot price, averaged, as the finder shows it with that region selected. On-demand: the same region's price. Per vCPU-hour: the spot price, or without spot the on-demand price, per vCPU. Every region is under Prices by region.
Description #
The memory-optimized R7IZ instances, generally available since September 7, 2023, feature 4th Generation Intel Xeon Scalable processors (Sapphire Rapids) with a 3.9 GHz sustained all-core turbo frequency. These high-frequency instances deliver up to 50 Gbps of networking and 40 Gbps of EBS bandwidth, utilize DDR5 memory, and are EBS-only for storage, making them ideal for high-performance databases and EDA workloads.
