The Skylake has 48 hardware threads vs. Centriq’s 46. In terms of CPU cores, Skylake has 24 (the test was conducted on a dual-socket system) vs. Centriq’s 46 (single-socket). So one may justify Centriq’s higher throughput by its higher core count. But when power efficiency is taken into consideration, that justification is no longer sufficient:
On the NGINX web server, …the [Centriq] chip did 214 requests per second per watt, compared to 99 for the Skylake chip….
Of course, higher count of less powerful cores has always been a strategy of many of Intel’s competitors (witness the more recent SPARC processors), but they are suitable mostly for embarrassingly parallelizable software. Unfortunately, many mission-critical software systems are not like that. For example, banking, ERP, and CRM systems are ultimately bottlenecked by their need to maintain accurate state information (in databases).
