Amd Epyc 7571 Vs Intel Skylake E5 2686 V5

In the realm of server computing, the competition between AMD and Intel has been heating up in recent years. With the advent of AMD’s EPYC processors, the company has made significant strides in challenging Intel’s dominance in the server market. This blog post will delve into a detailed comparison between two server CPUs, the AMD EPYC 7571 and the Intel Skylake E5-2686 v5, to help you make an informed decision about which CPU is right for your specific needs.

Architecture and Specifications

The AMD EPYC 7571 is based on the Zen 2 microarchitecture, while the Intel Skylake E5-2686 v5 is based on the Skylake microarchitecture. The EPYC 7571 features 32 cores and 64 threads, while the Skylake E5-2686 v5 has 24 cores and 48 threads. Both CPUs have a base clock speed of 2.2 GHz, but the EPYC 7571 has a higher boost clock speed of 3.6 GHz compared to the Skylake E5-2686 v5’s 3.3 GHz.

Performance

When it comes to performance, both CPUs offer impressive capabilities. The EPYC 7571 excels in multi-threaded workloads due to its higher core count and larger cache. It delivers a substantial performance advantage over the Skylake E5-2686 v5 in tasks such as virtualization, database processing, and cloud computing.

Power Consumption and Efficiency

Power consumption is a critical factor to consider when choosing a server CPU. The EPYC 7571 has a TDP (Thermal Design Power) of 225W, while the Skylake E5-2686 v5 has a TDP of 165W. This means that the EPYC 7571 consumes more power than the Skylake E5-2686 v5. However, the EPYC 7571’s higher performance often compensates for the increased power consumption.

Memory Support

Both the EPYC 7571 and the Skylake E5-2686 v5 support DDR4 memory. The EPYC 7571 supports up to 2 TB of memory with a maximum speed of DDR4-3200, while the Skylake E5-2686 v5 supports up to 1 TB of memory with a maximum speed of DDR4-2400. The EPYC 7571’s larger memory capacity and faster memory support give it an advantage in memory-intensive applications.

Features and Technologies

The EPYC 7571 and the Skylake E5-2686 v5 offer a range of features and technologies to enhance their performance and efficiency. The EPYC 7571 supports AMD’s Infinity Fabric technology, which provides high-speed interconnects between the CPU cores and other components. It also supports AMD’s Secure Encrypted Virtualization (SEV) technology, which enhances security by encrypting virtual machines (VMs). The Skylake E5-2686 v5 supports Intel‘s VT-d virtualization technology and Intel’s Trusted Execution Technology (TXT), which provides additional security features.

Price and Availability

The AMD EPYC 7571 is priced at around $2,000, while the Intel Skylake E5-2686 v5 is priced at around $1,500. Both CPUs are widely available from major retailers and distributors.

Choosing the Right CPU for Your Needs

The choice between the AMD EPYC 7571 and the Intel Skylake E5-2686 v5 ultimately depends on your specific requirements. If you need a high-performance CPU for multi-threaded workloads, the EPYC 7571 is the better choice. If power consumption is a primary concern, the Skylake E5-2686 v5 may be a more suitable option.

The Verdict

In this battle of server CPUs, the AMD EPYC 7571 emerges as the winner. It offers superior performance, memory support, and features compared to the Intel Skylake E5-2686 v5. While the Skylake E5-2686 v5 has a lower price and lower power consumption, the EPYC 7571’s advantages in performance and scalability make it the more compelling choice for most demanding server applications.
