🚀 Say hello to TPU v7 — Ironwood! Google just dropped their latest TPU generation, matching Blackwell vibes. We're talking 4.6 dense petaflops per chip — a smidge more than the B200. 💪
With 192GB of video memory, it falls slightly short on bandwidth (7.4TB/s vs. 8TB/s for B200). But hey, energy efficiency? It's twice as good as Trillium (v6e) and a tad better than Blackwell! 🌱
These new TPUs can jam together into pods with over 9000 chips! Instead of Infiniband/Ethernet, there’s custom networking that’s kinda like what Nvidia does in NVL72. Unlike Nvidia's promise of scaling only up to 576 chips by 2027 via NVLink, these bad boys can scale to thousands! 🙌
But let’s keep it real — they’re giving only 1.2TB/s per chip, while NVLink 5 in Blackwell GPUs hits 1.8TB/s. 😬
The big question is: can they snag enough HBM for mass deployments? Even if they do, with all those impressive specs, it won't outshine Nvidia just yet. Why? Google isn’t selling TPUs; they’re renting them out in the cloud! And don’t forget — they’re still stacking up on GPUs too; they dropped $10 billion on Blackwells primarily for Google Cloud! 💰💻 #TPUv7 #Google #AIRevolution
