The IBM Power E1080 (Power10) is a major architectural upgrade over Power9 systems (like E980, S924, etc.), and the differences are not just incremental—they are multi-dimensional improvements in performance, memory, security, and efficiency.

Here’s a clear, structured comparison:

⚡ 1. Processor architecture upgrade (Power10 vs Power9)

🔷 Power9 (older generation)

• Built on 14nm process
• SMT4 or SMT8 core configurations
• Designed mainly for strong throughput and I/O-heavy workloads

🔷 Power10 (E1080)

• Built on 7nm EUV process (Samsung)
• More efficient core design with higher IPC (instructions per cycle)
• Up to ~30% better per-core performance depending on workload

👉 Impact:

• Power10 delivers more work per core, reducing the number of cores needed for the same workload.

🚀 2. System-scale performance (E1080 vs Power9 E980)

• E1080 delivers about 1.5× to 1.6× more system capacity than Power9 E980 systems

👉 Meaning:

• A single E1080 system can replace larger Power9 deployments
• Higher throughput in consolidated environments (SAP, Oracle, Db2)

🧠 3. Memory subsystem (major leap forward)

Power9:

• Traditional DDR4 memory architecture
• Good capacity but higher latency at scale

Power10 (E1080):

• Open Memory Interface (OMI) architecture
• Much higher memory bandwidth and efficiency
• Up to 2× better memory reliability and availability vs industry DIMMs

👉 Impact:

• Faster SAP HANA queries
• Better handling of very large in-memory databases
• Reduced memory bottlenecks under heavy load

🔐 4. Security improvements (huge generational jump)

Power9:

• Strong enterprise security but mostly software-assisted encryption

Power10 (E1080):

• Transparent memory encryption (hardware-native, always-on)
• 4× more cryptographic engines per core than Power9

👉 Impact:

• Much faster encryption without CPU penalty
• Better protection for hybrid cloud and multi-tenant workloads
• Security is built into hardware, not layered on top

⚙️ 5. AI and workload acceleration

Power9:

• Limited AI acceleration support

Power10:

• Built-in AI inference acceleration
• ~5× faster in-core inferencing vs Power9 (specific workloads)

👉 Impact:

• Better performance for analytics, fraud detection, and real-time AI inference inside enterprise systems

🔄 6. Virtualization and workload consolidation

Power9:

• Strong PowerVM virtualization (already industry-leading)

Power10:

• Improved efficiency + higher core density
• Better LPAR scaling and resource sharing

👉 Impact:

• More workloads per system
• Lower cost per VM/LPAR
• Better utilization of hardware

🌡️ 7. Power efficiency and density

• Power10 systems deliver higher performance per watt than Power9
• More compute in similar or lower energy envelope

👉 Impact:

• Lower data center footprint
• Reduced operational cost for large enterprises

📊 Side-by-side summary

🧠 In simple terms

Compared to Power9, the IBM Power E1080 is not just faster—it is fundamentally more advanced:

• Faster cores (more work per CPU cycle)
• Much faster memory system (critical for SAP HANA)
• Stronger built-in security (hardware-level encryption)
• Better AI and analytics acceleration
• Higher consolidation efficiency (fewer servers needed)

🏁 Bottom line

Power E1080 (Power10) improves on Power9 by:

👉 ~1.5× system performance gain
👉 ~20–30% per-core improvement
👉 Major leap in memory, security, and AI acceleration
👉 Better efficiency and consolidation for enterprise workloads
