What To Know

  • The EPYC 9654, for example, has a TDP of 360W, while the Intel Xeon Platinum 8490H has a TDP of 400W.
  • In general, EPYC Genoa CPUs tend to excel in multi-threaded workloads, while Sapphire Rapids CPUs may have an advantage in single-threaded performance.
  • On the other hand, if single-threaded performance or a lower price point is more important, then Intel Sapphire Rapids may be a better choice.

The server market is constantly evolving, with new technologies emerging to meet the ever-increasing demands of modern workloads. Two of the leading players in this space are AMD and Intel, who have recently released their latest server CPU generations: AMD EPYC Genoa and Intel Sapphire Rapids. In this comprehensive guide, we will delve into the key differences between these two formidable CPUs, providing you with the insights to make an informed decision for your server needs.

Architecture and Core Count

AMD EPYC Genoa is built on the Zen 4 architecture, featuring up to 96 cores per socket. Intel Sapphire Rapids, on the other hand, utilizes the Golden Cove architecture and supports up to 60 cores per socket. Both CPUs offer significant core density, enabling them to handle demanding multi-threaded workloads efficiently.

Clock Speeds and Cache

AMD EPYC Genoa boasts higher base and boost clock speeds compared to Intel Sapphire Rapids. The EPYC 9654, for instance, has a base clock of 2.0 GHz and a boost clock of 3.7 GHz. In contrast, the Intel Xeon Platinum 8490H has a base clock of 2.0 GHz and a boost clock of 3.5 GHz. Additionally, EPYC Genoa CPUs feature a larger L3 cache size, providing faster access to frequently used data.

Memory Support

AMD EPYC Genoa supports DDR5 memory with speeds up to 5200 MT/s, while Intel Sapphire Rapids supports DDR5 memory with speeds up to 4800 MT/s. Both CPUs offer significant memory bandwidth, crucial for applications that require large amounts of memory access.

I/O Connectivity

AMD EPYC Genoa and Intel Sapphire Rapids provide a wide range of I/O connectivity options. EPYC Genoa supports up to 128 PCIe 5.0 lanes, while Sapphire Rapids supports up to 80 PCIe 5.0 lanes. Additionally, both CPUs offer multiple USB ports, SATA ports, and Ethernet controllers for flexible connectivity.

Power Consumption and Efficiency

Power consumption is a critical factor for server environments. AMD EPYC Genoa CPUs are designed to be more power-efficient than their Intel counterparts. The EPYC 9654, for example, has a TDP of 360W, while the Intel Xeon Platinum 8490H has a TDP of 400W. This lower power consumption can lead to significant cost savings over time.

Performance Benchmarks

In terms of performance, both AMD EPYC Genoa and Intel Sapphire Rapids deliver impressive results. However, the specific performance will vary depending on the workload and application. In general, EPYC Genoa CPUs tend to excel in multi-threaded workloads, while Sapphire Rapids CPUs may have an advantage in single-threaded performance.

Pricing and Availability

AMD EPYC Genoa CPUs are currently available for purchase, while Intel Sapphire Rapids CPUs are expected to be released in the coming months. Pricing for both CPUs will vary depending on the specific model and configuration.

Final Thoughts

Choosing between AMD EPYC Genoa and Intel Sapphire Rapids depends on the specific requirements of your server environment. If you prioritize core count, clock speeds, and power efficiency, then AMD EPYC Genoa is a compelling option. On the other hand, if single-threaded performance or a lower price point is more important, then Intel Sapphire Rapids may be a better choice. Ultimately, the best decision will depend on a careful evaluation of your workload and budget.
