Azure SQL Database – Hyperscale tier, the Standard-series (Gen5) and Premium-series

Posted by

In Azure SQL Database – Hyperscale tier, the Standard-series (Gen5) and Premium-series hardware options differ in CPU architecture, memory, storage throughput, and performance characteristics.

Here’s a clear comparison:


🧾 Standard-series (Gen5) vs Premium-series in Hyperscale

FeatureStandard-series (Gen5)Premium-series
CPUIntel-based (older Gen5 CPUs)Intel Ice Lake (latest high-performance CPUs)
Memory per vCore~5.1 GB~7 GB (more memory per vCore)
I/O ThroughputStandard (good for general-purpose workloads)Higher IOPS and throughput for intensive workloads
LatencyModerateLower latency, better for real-time apps
Best ForGeneral-purpose workloads, balanced compute/memoryHeavy workloads, analytics, concurrent queries, ML models
PriceLowerHigher cost (but more performance per vCore)
Auto-scalingSupportedSupported

🔍 Use Case Guidance

ScenarioRecommended Series
OLTP apps, business apps✅ Standard-series (Gen5)
High concurrency / parallel queries✅ Premium-series
In-memory workloads / caching✅ Premium-series
Budget-sensitive environments✅ Gen5
Large-scale reporting or analytics✅ Premium-series

Price-wise comparison between Standard-series (Gen5) and Premium-series in Azure SQL Database – Hyperscale tier

Here’s a price-wise comparison between Standard-series (Gen5) and Premium-series in Azure SQL Database – Hyperscale tier. Prices vary by region and licensing model, but I’ll use approximate pricing in USD for the West US region under the vCore-based model (as of May 2025, pay-as-you-go pricing, license included):


💰 Hyperscale Price Comparison (Approx. per vCore/hour)

vCore CountStandard-series (Gen5)Premium-series
2 vCores~$0.376/hour~$0.482/hour
4 vCores~$0.752/hour~$0.964/hour
8 vCores~$1.504/hour~$1.928/hour
16 vCores~$3.008/hour~$3.856/hour
32 vCores~$6.016/hour~$7.712/hour
64 vCores~$12.032/hour~$15.424/hour

📌 Note: These prices include the SQL license. You can save ~40% using Azure Hybrid Benefit (if you already have SQL Server licenses).


📊 Monthly Estimation (730 hours)

4~$549~$704
8~$1,098~$1,408
16~$2,196~$2,816
32~$4,392~$5,632

Key Takeaway

  • Premium-series is ~28–30% more expensive than Standard Gen5.
  • But it offers ~35–50% more memory, better CPU, and higher IOPS — suitable for high-performance workloads.

SQL hardware configuration for Azure SQL Database (Hyperscale)

SQL hardware configuration for Azure SQL Database (Hyperscale), here’s a breakdown of the differences between the Standard-series (Gen5) and the Premium-series options:


🔍 Side-by-Side Comparison

FeatureStandard-series (Gen5)Premium-seriesPremium-series – Memory Optimized
DescriptionBalanced memory and computeBalanced memory and compute (newer CPU)Higher memory per vCore
Max vCores8012880
Max Memory415.23 GB625 GB830.47 GB
Compute Cost / vCore / Month$196.98$196.95$249.73
CPU ArchitectureIntel Broadwell/Haswell (older)Intel Ice Lake (latest gen)Intel Ice Lake (optimized for memory)
Use CaseGeneral workloads, good balanceHigher concurrency, newer CPU for same costMemory-heavy workloads (analytics, ML, large joins)
Performance-to-Price RatioGoodBetter than Gen5 (same cost, newer CPU)Best for high memory needs, but costlier
Storage LimitScales independently (Hyperscale)SameSame

Key Takeaways

  • Gen5 and Premium-series (non-memory optimized) have almost the same cost per vCore.
  • Premium-series offers more memory and vCore scale, so it’s a better deal for most production workloads.
  • Memory Optimized Premium is ~27% more expensive, but gives double the memory of Gen5 — great for memory-intensive tasks.
