Intel Xeon 6780E / Xeon 6766E 144-Core Performance Benchmarks
Ignore the 1P vs. 2P difference due to NUMA behavior in this database workload, but what was most interesting here was the power efficiency. While the Xeon 6766E/6780E were slower than the Intel Xeon Sapphire Rapids and Emerald Rapids processors, it did lead in the best performance-per-Watt across any of the processors tested for ClickHouse. The generational uplift in power efficiency was huge and the Xeon 6700E series proved to be very capable for energy efficient database workloads.
With the PostgreSQL 16 database server, the Xeon 6780E outperformed the AMD EPYC 9654 / 9754 / 9684X flagship processors in higher throughput and lower latency.
And the PostgreSQL numbers became all the more exciting when pulling up the CPU power consumption numbers... The Xeon 6780E was consuming 172 Watts on average for its 144 cores and a peak of 191 Watts while the EPYC 9654 had a 254 Watt average and 305 Watt peak. The Xeon 6780E was running at 67% the power consumption of that flagship EPYC Genoa SKU while delivering better performance. Even two of the Xeon 6780E processors were less on average than a single EPYC 9654.
With the Meta/Facebook RocksDB persistent key-value store, the Xeon 6766E and Xeon 6780E were delivering great raw performance and big wins for performance-per-Watt over the current AMD 4th Gen EPYC processors and remarkable generational power efficiency compared to prior Xeon Scalable processors.
