What To Know
- While the Xeon has a slightly higher turbo boost, the EPYC 9654’s higher core count and Zen 4 architecture provide a substantial performance advantage in most workloads.
- The AMD EPYC 9654 has a TDP of 360W, while the Intel Xeon Platinum 8380 has a TDP of 270W.
- However, if you are on a tighter budget or have a workload that does not fully utilize all 64 cores, the Xeon Platinum 8380 is a more cost-effective option.
In the realm of high-performance computing, the battle between AMD EPYC and Intel Xeon processors has been raging for years. As technology advances, each new generation of CPUs promises greater power, efficiency, and value. In this comprehensive guide, we will pit the formidable AMD EPYC 9654 against its arch-rival, the Intel Xeon Platinum 8380, to determine which processor emerges victorious.
Core Count and Architecture
The AMD EPYC 9654 boasts an impressive 64 cores and 128 threads, while the Intel Xeon Platinum 8380 features 40 cores and 80 threads. Both processors utilize a multi-chip module (MCM) design, which allows for more cores to be packed onto a single die. However, the EPYC 9654 has a unique advantage with its Zen 4 architecture, which offers significant performance improvements over its predecessor, Zen 3.
Clock Speed and Turbo Boost
The AMD EPYC 9654 has a base clock speed of 2.0 GHz and a turbo boost speed of up to 3.7 GHz. The Intel Xeon Platinum 8380 has a base clock speed of 2.4 GHz and a turbo boost speed of up to 4.0 GHz. While the Xeon has a slightly higher turbo boost, the EPYC 9654’s higher core count and Zen 4 architecture provide a substantial performance advantage in most workloads.
Cache Memory
The AMD EPYC 9654 features a massive 384 MB of L3 cache, while the Intel Xeon Platinum 8380 has 256 MB of L3 cache. Cache memory is crucial for storing frequently accessed data and instructions, and the larger cache size of the EPYC 9654 can significantly reduce memory latency and improve overall performance.
Memory Support
The AMD EPYC 9654 supports up to 4 TB of DDR5 memory, while the Intel Xeon Platinum 8380 supports up to 2 TB of DDR4 memory. DDR5 memory offers higher bandwidth and lower power consumption than DDR4, providing a significant advantage to the EPYC 9654 in memory-intensive applications.
Power Consumption and Efficiency
The AMD EPYC 9654 has a TDP of 360W, while the Intel Xeon Platinum 8380 has a TDP of 270W. TDP (Thermal Design Power) measures the maximum amount of heat a processor can dissipate. The higher TDP of the EPYC 9654 indicates that it may require more cooling and power consumption than the Xeon. However, the EPYC 9654’s superior performance and Zen 4 architecture may offset its higher power consumption.
Benchmark Comparisons
In synthetic benchmarks, the AMD EPYC 9654 consistently outperforms the Intel Xeon Platinum 8380. For example, in the SPECrate2017_fp benchmark, the EPYC 9654 achieved a score of 1250, compared to 920 for the Xeon. In real-world applications, the EPYC 9654 also shines, particularly in workloads that require high core counts and memory bandwidth.
Price and Value
The AMD EPYC 9654 has a list price of $12,285, while the Intel Xeon Platinum 8380 costs $10,009. While the Xeon is slightly cheaper, the EPYC 9654 offers significantly better performance, making it a better value for most buyers.
Choosing the Right Processor for Your Needs
The choice between the AMD EPYC 9654 and Intel Xeon Platinum 8380 depends on your specific workload and requirements. If you need the highest possible performance, the EPYC 9654 is the clear winner. Its high core count, large cache, and DDR5 memory support make it ideal for demanding applications such as data analytics, machine learning, and virtualization. However, if you are on a tighter budget or have a workload that does not fully utilize all 64 cores, the Xeon Platinum 8380 is a more cost-effective option.
