Diving deeper into individual workloads shows a complex picture. X925 trades blows with the higher clocked Intel and AMD cores in core-bound workloads. 548.exchange2 and 500.perlbench both show the advantages of clock speed scaling, with Intel and AMD’s higher clocking 8-wide cores easily outpacing Arm’s 4 GHz 10-wide one. But 525.x264 turns things around. Cortex X925 is able to finish that workload with fewer instructions than its x86-64 peers, while maintaining a large IPC advantage. X925 continues to do well in workloads that challenge the branch predictor, like 541.leela and 505.mcf. Finally, memory bound tests like 520.omnetpp are heavily influenced by factors outside the core.
