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.

但这场辩论本身可能就问错了问题。正如未来学家托马斯·弗雷所指出的，根本不存在"完美"的机器人形态，就像不存在"完美"的交通工具一样——摩托车、轿车、卡车、坦克各有其用，没人会争论哪一种universally superior（普遍更优）。机器人的形态应该服务于场景，而非相反。
The chip that runs the Neo is significantly less powerful than the M5 you'll find in the MacBook Air too. The Neo uses an A18 Pro, which is the chip that debuted in the iPhone 16 Pro and iPhone 16 Pro Max. It has a 6-core CPU (two performance, four efficiency), 5-core GPU and 16-core Neural Engine. Measure that against the Air's M5, the base version of which has a 10-core CPU (four super cores, six efficiency cores) and 8-core GPU, though that too has a 16-core Neural Engine.
