AMD has once again proven its dominance in the CPU market with the release of its Zen 4c Siena CPUs. These powerful processors have outpaced Intel’s Sapphire Rapids Xeon chips in terms of speed, affordability, and efficiency. AMD has introduced two server families based on the Zen 4c architecture: Bergamo with 128 cores and Siena with 64 cores. While Bergamo focuses on compute density and core counts, Siena is aimed at cost-effective establishments that are conscious of their power bills.
The flagship model of the Siena family is the EPYC 8534P, which boasts 64 cores and a boost clock of 3.1GHz. It has a stock TDP of 200W, which can be adjusted from 155W to 255W. Retailing at $4950, the Epyc 8534P supports all Zen 4 features, including AVX-512, hex-channel DDR5-4800 memory, and 96 PCIe Gen 5 lanes.
Phoronix, a reputable tech publication, conducted tests on the Epyc 8534P and its PN variant, and the results were impressive. In rendering workloads like Blender, the Epyc 8534P was found to be approximately 50% faster than Intel’s Xeon Platinum 8468 (Sapphire Rapids) while consuming significantly less power. Even in the 155W mode, the Epyc processor managed to outperform the Xeon while drawing just over 120W of power.
When it comes to SHA256 encryption, a standard for SSL-secured domains, the AMD Siena flagship proved to be 64% faster than the Xeon Platinum 8468 in the 225W mode. Even in the 155W profile, it still outperformed the Xeon by 20%. The power consumption monitor also revealed that the Epyc 8534P drew 100W less power than the Xeon Platinum 8468 in the 225W mode, reducing it to nearly a third in the 155W mode.
Apache Cassandra, an essential component of server backends, also showcased the superiority of the Epyc 8534P. With a throughput of 265.67K ops per sec, it outperformed the Xeon 8468 by 110K. Additionally, the Siena flagship consumed only half as much power as its Sapphire Rapids rival in this test.
The Epyc 8534P’s performance-cost ratio was also commendable. It offered 45 ops per dollar, dwarfing the Xeon 8468’s 18.6 ops per dollar output. Even with the cTDP set to 155W, the Epyc processor maintained an impressive performance-cost ratio of 39.50 ops per dollar.
PostgreSQL 16, a widely used database management system, favored the Siena processors. The Epyc 8534 achieved 2.29 million TPS at 155W and an astounding 3.15 million TPS at 225W cTDP. In comparison, the Xeon Platinum 8468 was limited to just 2 million TPS, highlighting a significant performance gap between the two.
Overall, the power consumption graphs remained consistent with previous tests. The Epyc 8534P peaked at 220W in the 225W power mode, while the Xeon exceeded 300W and reached its 350W power limit across all scenarios.
When considering the performance-cost factor, the Epyc Siena flagship once again emerged as the clear winner. It delivered an impressive 538 TPS per dollar, compared to just 251 TPS on the Xeon competition.
AMD’s Zen 4c Siena CPUs have undoubtedly raised the bar for server processors. With their exceptional speed, affordability, and efficiency, these processors have firmly established AMD as a formidable competitor to Intel in the data center market.
