X925’s frontend can sustain 10 instructions per cycle, but strangely has lower throughput when using 4 KB pages. Using 2 MB pages lets it achieve 10 instructions per cycle as long as the test fits within the 64 KB instruction cache. Cortex X925 can fuse NOP pairs into a single MOP, but that fusion doesn’t bring throughput above 10 instructions per cycle. Details aside, X925 has high per-cycle frontend throughput compared to its x86-64 peer, but slightly lower actual throughput when considering Zen 5 and Lion Cove’s much higher clock speed. With larger code footprints, Cortex X925 continues to perform well until test sizes exceed L2 capacity. Compared to X925, AMD’s Zen 5 relies on its op cache to deliver high throughput for a single thread.
