"small increase in clock speed"
First and foremost, a CPU must run reliably. Only if that is true, you can fiddle with runtime.
The homebrew Yitian 710 CPU developed in 2021 and deployed by Alibaba Cloud is the fastest Arm server processor for rent in hyperscale clouds when handling database-related tasks, according to research published this week in the Institute of Electrical and Electronics Engineers journal Transactions on Cloud Computing. A paper …
Interesting article and paper! From Loghin's abstract one sees that the study covered: "in-memory key-value stores, relational databases, enterprise blockchains, and Machine Learning inference" and for some of those at least, the DDR5 of the Yitian 710 (Neoverse N2) really helps, along with the higher clock (3.2 GHz). Those two combined may explain the better perf compared to Altra (Neoverse N1, DDR4, 3.0 GHz), and the clock gives it a 20% advantage over Graviton 3 (Neoverse V1, DDR5, 2.6 GHz). A nice chip, and it will be interesting to compare it to Graviton 4 and Ampere Siryn when they become available.
Also, the abstract notes that "performance of OLAP, ML inference, and blockchain on ARM-based servers is below that of Xeon" suggesting room for improvements (work cut-out for ARM) as nicely explained in the article (clock speed, software optimization, ...). Riveting competition!
