With the EPYC Siena focus on telco and edge computing, Apache IoTDB was one of the databases used for testing. With the EPYC 8324P and 8324PN processors we see these 32 Zen 4C cores are capable of performing very competitively to Intel Xeon Scalable Sapphire Rapids at the same core count. The Xeon Gold 6421N did have a slight lead in the raw IotDB performance to not much surprise considering the 6421N has a turbo frequency up to 3.6GHz compared to the 8324P at 3.1GHz. But when the Xeon Gold 6421N was running with just six memory channels, the EPYC 8324P did manage to outperform it.

The EPYC 8424P / 8324PN processors really come out ahead when it comes to the performance-per-dollar based on the CPU pricing and the number of used DDR5 memory modules.

While the EPYC 8324P was pulling just around 69 Watts on average during this IotDB benchmark, the Xeon Gold 6421N was pulling around 114 Watts, 65% higher power consumption while delivering similar raw performance.

ClickHouse benchmark with settings of 100M Rows Hits Dataset, First Run / Cold Cache. Xeon Gold 6421N was the fastest.
ClickHouse benchmark with settings of 100M Rows Hits Dataset, Third Run. Xeon Gold 6421N was the fastest.

The ClickHouse database was similar in that the Xeon Gold 6421N with eight memory channels was coming in just ahead of the EPYC Siena 32-core competition but at six memory channels, both the EPYC 8324PN and 8324P parts came out ahead.

Where EPYC Siena proved very compelling was in delivering significantly better performance-per-Watt than the 32-core Xeon Scalable Sapphire Rapids server.

The TiDB database performance leaned in favor of the Xeon Gold 6421N with its higher turbo frequency but when it comes to value and power efficiency, the AMD EPYC Siena processors were easily commanding the top spot.
