Why it matters
Running an AI model after it is trained — the step called inference — is becoming the main hardware fight in enterprise AI. Google and Nvidia used 2025 product launches to pitch cheaper, more efficient ways to serve models in production. (blog.google) (nvidia.com) Google introduced Ironwood on April 9, 2025, calling it its seventh-generation Tensor Processing Unit and its first chip designed specifically for inference. Google said Ironwood scales to 9,216 chips per pod and reaches 42.5 exaflops at that size. (blog.google) In plain terms, inference is the part customers pay for every time a model answers a prompt, summarizes a document, or runs an agent step. Google’s TPU7x documentation says Ironwood is aimed at dense models, mixture-of-experts models, sampling, and decode-heavy inference, with 192 gigabytes of high-bandwidth memory per chip and 4,614 teraFLOPS of FP8 peak compute per chip. (docs.cloud.google.com) Nvidia took a different angle in March 2026 with the RTX PRO 4500 Blackwell Server Edition, a lower-power server GPU aimed at enterprise and edge deployments. Nvidia says the card uses a 165-watt power envelope and a single-slot form factor, which lets it fit into more standard server designs than larger AI accelerators. (nvidia.com) (pny.com) That packaging matters because many companies are no longer shopping only for the fastest training cluster. Nvidia’s Blackwell inference blog says production AI now depends on compute, networking, storage, power, cooling, and software working as one system, while Google positions Ironwood as part of its AI Hypercomputer stack with Pathways software and Google Kubernetes Engine support. (blogs.nvidia.com) (blog.google) (docs.cloud.google.com) The shift reflects how enterprise AI spending has changed over the last year. Training a model is a one-time or occasional cost, but inference repeats every time employees query a chatbot, a search engine rewrites results, or a customer-service agent calls multiple models in sequence. (blogs.nvidia.com) (blog.google) Google’s pitch is scale and vertical integration. The company says Ironwood is liquid-cooled, linked by its Inter-Chip Interconnect network, spans nearly 10 megawatts at full pod scale, and plugs into Google Cloud services and software tuned around its own silicon. (blog.google) (cloud.google.com) Nvidia’s pitch is breadth. The RTX PRO 4500 Blackwell Server Edition is available through server partners and marketplaces, and partner datasheets list 32 gigabytes of GDDR7 memory on a PCI Express Gen5 card built for cloud, data center, and edge systems. (nvidia.com) (lenovopress.lenovo.com) (techpowerup.com) Both companies are arguing, in different ways, that AI buyers should judge infrastructure by the cost of useful output, not just peak chip speed. The next test is whether enterprises buying copilots, search, and agent software decide that the cheapest token comes from the tightest stack or the most flexible one.
