My impression is that RDBMS workloads are generally far more IO-intensive than CPU-intensive.

Looking at my own Azure SQL CPU vs IO vs Log charts right now, even with some CPU-heavy OLAP queries barely passes 25% CPU in the 2 vCore-sized database used in my current main project.

Wouldn't a DB benefit enormously from faster memory access? Perhaps you're only getting 25% CPU usage because the CPU is stalled waiting for main memory to reply...
