PMU data indicates X925 is able to maintain higher IPC relative to the competition. Unfortunately for X925, several tests require many more instructions to complete with the aarch64 instruction set compared to x86-64. Arm needs a large enough IPC advantage to overcome both a clock speed deficit and a less efficient representation of the work. Cortex X925 does achieve high IPC, but it’s not high enough.
