Cortex X925’s branch target caching compares well too. Arm has a large first level BTB capable of handling two taken branches per cycle. Capacity for this first level BTB varies with branch spacing, but it seems capable of tracking up to 2048 branches. This large capacity brings X925’s branch target caching strategy closer to Zen 5’s, rather than prior Arm cores that used small micro-BTBs with 32 to 64 entries. For larger branch footprints, X925 has slower BTB levels that can track up to 16384 branches and deliver targets with 2-3 cycle latency. There may be a mid-level BTB with 4096 to 8192 entries, though it’s hard to tell.
