Google pairing TPUs with a Marvell-built memory processing unit is an admission that the bottleneck is now memory bandwidth and locality, not raw flops. If you're designing AI workloads, architecture decisions around parameter sharding, KV cache, and sequence length are about to be constrained — or unlocked — by how fast your memory fabric evolves, not your GPU count.
