而拿下 Meta 这个全球最贪婪的算力吞噬兽，无疑是谷歌向英伟达下达的最强战书。同时，谷歌在底层软件生态上的妥协也立了大功——TPU 近期大幅优化了对 PyTorch（Meta 主导的 AI 框架）的原生支持，这让 Meta 的研发团队终于可以顺滑地将模型迁移到谷歌的硬件上。

Arm offers 2 MB 8-way and 3 MB 12-way L2 cache options. Mediatek and Nvidia chose the 2 MB option, and testing shows it has 12 cycles of latency. THis low cycle count latency lets Arm remain competitive against Intel and AMD’s L2 caches, despite running at lower clock speeds. L2 bandwidth comes in at 32 bytes per cycle for reads, and increases to approximately 45 bytes per cycle with a read-modify-write pattern.
