Both chips boast impressive specifications and cutting-edge technologies, making them ideal for demanding workloads such as virtualization, database management, and cloud computing. In this blog post, we will delve into an in-depth comparison of the AMD EPYC 7313 vs. Intel Xeon Gold 6326, examining their key features, performance benchmarks, and suitability for different applications.
Core Count and Architecture
The AMD EPYC 7313 is a 32-core processor based on the Zen 2 microarchitecture, while the Intel Xeon Gold 6326 packs 24 cores based on the Skylake-SP architecture. The EPYC 7313’s higher core count gives it an advantage in highly threaded workloads that can leverage multiple cores simultaneously. On the other hand, the Xeon Gold 6326’s Skylake-SP architecture offers optimizations for single-threaded performance, making it suitable for applications that require high clock speeds.
Clock Speed and Cache
The AMD EPYC 7313 has a base clock speed of 3.0 GHz and a turbo boost speed of up to 3.7 GHz. The Intel Xeon Gold 6326 operates at a higher base clock speed of 3.4 GHz and a turbo boost speed of up to 4.4 GHz. However, the EPYC 7313 compensates for its lower clock speed with a larger cache size. It features 256 MB of L3 cache, while the Xeon Gold 6326 has only 38.5 MB of L3 cache. The larger cache size on the EPYC 7313 can improve performance for applications that require frequent access to large datasets.
Memory Support
Both the AMD EPYC 7313 and Intel Xeon Gold 6326 support up to 2 TB of DDR4 memory. However, the EPYC 7313 offers a wider memory bandwidth of 256 GB/s compared to the Xeon Gold 6326’s 170 GB/s. The higher memory bandwidth on the EPYC 7313 can enhance performance in memory-intensive applications such as databases and virtual machines.
I/O and Connectivity
The AMD EPYC 7313 and Intel Xeon Gold 6326 provide a range of I/O and connectivity options. Both processors support PCIe 4.0, which offers double the bandwidth of PCIe 3.0. The EPYC 7313 has 128 PCIe 4.0 lanes, while the Xeon Gold 6326 has 64 PCIe 4.0 lanes. The additional PCIe lanes on the EPYC 7313 allow for more flexible expansion options and increased I/O performance.
Power Consumption and Efficiency
The AMD EPYC 7313 has a TDP of 280W, while the Intel Xeon Gold 6326 has a TDP of 205W. The lower TDP on the Xeon Gold 6326 makes it more energy-efficient, resulting in lower operating costs for data centers. However, the EPYC 7313’s higher core count and larger cache size may outweigh its higher power consumption in certain workloads.
Performance Benchmarks
In real-world performance benchmarks, the AMD EPYC 7313 and Intel Xeon Gold 6326 exhibit similar performance in single-threaded applications. However, the EPYC 7313’s higher core count and larger cache size give it a significant advantage in multi-threaded workloads. For example, in the SPECint2017 integer benchmark, the EPYC 7313 outperforms the Xeon Gold 6326 by up to 30%.
Suitability for Different Applications
The AMD EPYC 7313 is an excellent choice for applications that require high core counts, large cache sizes, and high memory bandwidth. These applications include virtualization, database management, cloud computing, and big data analytics. The Intel Xeon Gold 6326 is better suited for applications that prioritize single-threaded performance and energy efficiency. These applications include web hosting, email servers, and small-scale virtual machines.
Key Points: A Balanced Choice
Both the AMD EPYC 7313 and Intel Xeon Gold 6326 are exceptional server processors that offer unique advantages for different applications. The EPYC 7313 excels in highly threaded workloads and memory-intensive applications, while the Xeon Gold 6326 provides higher single-threaded performance and energy efficiency. Ultimately, the best choice depends on the specific requirements of your workload and your budget.
