What To Know
- AMD EPYC Genoa is based on the Zen 4 architecture, featuring up to 96 cores per socket and a maximum frequency of 4.
- Intel Milan is based on the Ice Lake-SP architecture, featuring up to 40 cores per socket and a maximum frequency of 4.
- However, if you prioritize single-threaded performance or are on a tighter budget, Milan may be a better option.
The server market is a highly competitive landscape, with AMD and Intel vying for market dominance. The latest battleground in this rivalry is the server processor market, where AMD’s EPYC Genoa and Intel’s Milan processors are the current frontrunners. In this blog post, we will compare these two processors head-to-head, examining their features, performance, and value proposition to help you make an informed decision for your next server deployment.
Architecture
AMD EPYC Genoa
AMD EPYC Genoa is based on the Zen 4 architecture, featuring up to 96 cores per socket and a maximum frequency of 4.4 GHz. It supports up to 12 channels of DDR5 memory and offers PCIe 5.0 connectivity. Additionally, Genoa incorporates AMD‘s Infinity Fabric technology for enhanced inter-socket communication.
Intel Milan
Intel Milan is based on the Ice Lake-SP architecture, featuring up to 40 cores per socket and a maximum frequency of 4.3 GHz. It supports up to 8 channels of DDR4 memory and offers PCIe 4.0 connectivity. Milan utilizes Intel’s Ultra Path Interconnect (UPI) for inter-socket communication.
Performance
Core Count
Genoa’s higher core count (up to 96 cores) gives it a significant advantage in multi-threaded workloads, such as virtualization, cloud computing, and database applications.
Clock Speed
Milan’s slightly higher clock speed (4.3 GHz vs. 4.4 GHz) provides a slight edge in single-threaded performance, but the difference is negligible in most real-world scenarios.
Memory Bandwidth
Genoa’s support for DDR5 memory provides significantly higher memory bandwidth than Milan’s DDR4 support. This advantage is particularly beneficial for memory-intensive applications, such as in-memory databases and analytics.
PCIe Connectivity
Genoa’s PCIe 5.0 connectivity offers twice the bandwidth of Milan’s PCIe 4.0 connectivity. This increased bandwidth is essential for applications that require high-speed data transfer, such as artificial intelligence (AI) and machine learning (ML).
Value Proposition
Cost
Genoa processors are typically priced lower than comparable Milan processors, making them a more cost-effective option for budget-conscious organizations.
Performance per Dollar
Genoa offers superior performance per dollar compared to Milan, especially in multi-threaded workloads. This makes it an excellent choice for organizations that prioritize performance and value.
Use Cases
Genoa
- Virtualization and cloud computing
- Database applications
- High-performance computing (HPC)
- AI and ML
Milan
- Single-threaded applications
- Web hosting
- Enterprise resource planning (ERP)
- Email servers
Takeaways: The Verdict
The choice between AMD EPYC Genoa and Intel Milan depends on your specific workload requirements and budget. If you need a processor with high core counts, memory bandwidth, and PCIe connectivity for multi-threaded workloads, Genoa is the clear winner. However, if you prioritize single-threaded performance or are on a tighter budget, Milan may be a better option.
