We are excited to announce the GA (in selected regions) of new premium-series hardware configurations for Azure SQL Hyperscale databases.

 

Based on the latest generation of Intel® Xeon Scalable processors (3rd gen - Ice Lake) and AMD EPYC™ 7763v (Milan) chipsets, this premium-series hardware offers significantly improved performance and scalability over the standard-series (previously known as ‘Gen5’) hardware offerings and allows you to migrate your performance demanding workloads to Azure SQL Database Hyperscale. In addition, a new memory optimized option within the premium-series provides more memory per vCore to meet the needs of your most memory-intensive workloads.

 

The following table summarizes the key technical details for the new premium-series hardware:

 

Standard-series (Gen5)

Premium-series

Memory optimized premium-series

CPU

Standard-series Hyperscale databases are hosted on a variety of hardware including:

 

Intel® E5-2673 v4 (Broadwell);
Intel® SP-8160 (Skylake); Intel® 8272CL (Cascade Lake);

Intel® 8370C (Ice Lake);

AMD EPYC™ 7763v (Milan)

Premium-series Hyperscale databases are hosted only on latest hardware generation from Intel and AMD as follows:

Performance benefits

 

Faster CPU. A 60% increase in the maximum available number of vCores.

Faster CPU. Memory intensive workloads such as HTAP or analytics can benefit from 2x memory per vCore.

  • Both premium-series hardware options are using latest CPUs and memory technologies from Intel and AMD, which provide a boost to compute performance relative to standard-series hardware.
  • Premium-series option offers faster CPU performance compared to Standard-series and the ability to increase vCores by 60% by scaling up to 128 vCores.
  • Premium-series memory optimized option offers double the amount of memory relative to premium-series with up to 830 GB of memory at 80 vCores.
  • Due to the added memory and lower price, premium-series memory optimized option is a great alternative to M-series hardware in Azure SQL Database, which is to be retired in September 2023.

Comparison Demo

Here is a sample Hammer DB Demo running TPCC like workloads comparing Azure SQL Database Hyperscale Standard (Gen5) series vs Premium Series hardware showing a 20%+ improvement in performance at similar price point.

 

Current limitations to be noted: 

  • Premium-series (including memory optimized) is only supported in the following initial regions at the moment but regional availability will continue to improve over the coming months.

      • Australia East (including Zone redundancy)
      • Australia SouthEast 
      • Brazil South
      • Canada Central (including Zone redundancy)
      • Canada East
      • Central US (including Zone redundancy)
      • Central India
      • South India
      • East Asia
      • East US (including Zone redundancy)
      • East US2
      • France Central
      • Germany West Central
      • Japan East
      • Japan West
      • Northcentral US
      • North Europe (including Zone redundancy)
      • Southeast Asia
      • Southcentral US
      • Switzerland North
      • UK South (including Zone redundancy)
      • UK West 
      • West Europe (including Zone redundancy)
      • West Central US
      • West US 
      • West US 2 (including Zone redundancy)
      • West US 3 (including Zone redundancy)

    * Indicates that Premium-Series Memory Optimized hardware option is not yet available in that region.

  • Zone redundancy for premium-series and memory optimized premium-series is limited to a few regions as noted above, but expected to be more widely available over the coming months.
  • Azure SQL Database maintenance window is supported for premium-series and memory optimized premium-series in some of the regions but expected to be more widely available over the coming months.
  • Azure Reserved instance for Premium-series and memory optimized premium-series is now available as of November/2023
