Google reported that its TPU v4 delivered an average 2.1 times the per-chip performance of TPU v3 and 2.7 times the performance per watt. Those are Google’s 2023 averages, not guarantees for every model. The “more than doubles” headline also refers to a separate 2021 announcement: a TPU v4 pod capable of more than one exaflop of machine-learning computing power.
What Google meant by “more than doubles”
Google announced TPU v4 at Google I/O on May 18, 2021. The announcement described a pod with more than one exaflop of machine-learning computing power. That was a pod-level peak claim, not a statement that an individual TPU v4 chip was twice as fast as a TPU v3 chip.
In 2023, Google Cloud gave a more direct generation-to-generation comparison: TPU v4 averaged 2.1 times TPU v3’s performance per chip and 2.7 times its performance per watt. Google’s technical paper also said its TPU v4 supercomputer was nearly 10 times faster overall than its TPU v3 system, but the v4 system had four times as many chips—4,096—so that is a system-scale comparison, not a per-chip speedup. These figures are Google-reported results, not independent validation or a promise of the same improvement on every workload. Google Cloud’s 2023 TPU v4 report
What the pod’s exaflop figure describes
Google Cloud documentation specifies 4,096 TPU v4 chips per pod and a peak of 1.1 exaflops at BF16 or INT8 precision. The same reference lists a peak of 275 TFLOPS per chip at either of those precisions. These are peak arithmetic figures for specified low-precision formats; they are not application benchmarks, a general-purpose computing score, or evidence that a model will run at peak speed.

Google’s 2021 announcement compared one pod’s computing power to that of 10 million laptops. That is an illustrative analogy, not a standardized benchmark against a defined set of laptops. Google’s May 18, 2021 announcement
Why workloads can see different gains
Chip performance and power efficiency
The 2.1x performance and 2.7x performance-per-watt figures are averages reported by Google in 2023. A workload’s actual result depends on its model, precision, software, and system configuration; the averages should not be read as a guaranteed uplift for an individual job. Google Cloud’s TPU v4 reference lists 32 GiB of HBM2 memory per chip and 1,200 GB/s of memory bandwidth. It records measured minimum, mean, and maximum power of 90 W, 170 W, and 192 W, respectively. Google’s 2023 blog separately characterizes typical mean chip power as about 200 W; the two descriptions use different reporting contexts and should not be treated as identical measurements.

Embedding-heavy models
The TPU v4 paper describes SparseCores for work involving large embedding tables and reports 5x–7x acceleration for models that rely on embeddings, while using 5% of the die area and power. This is a paper-author claim for embedding-dependent models, not a general TPU v4 speedup for all machine-learning workloads. Jouppi et al., 2023 TPU v4 paper
Interconnect and system configuration
The paper also describes optical circuit switches that dynamically reconfigure the TPU pod’s interconnect. Performance at pod scale therefore reflects more than arithmetic units on a chip: networking, compiler behavior, and the overall system configuration matter. Google’s comparisons with other accelerator systems are likewise workload- and system-specific; they should not be treated as universal chip rankings.

How to interpret benchmark claims
Google’s MLPerf Training v1.0 post described submissions using TPU v4 pods, XLA compiler features, and configurations of up to 4,096 chips. A benchmark result is meaningful only with its version, model, chip count, software stack, and submission configuration attached. The post includes comparisons with earlier submissions and notes an exception for DLRM, so its reported speedups should not be generalized into one across-the-board TPU v4 multiplier.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Can you use TPU v4 through Google Cloud?
Google Cloud documents TPU v4 access through Google Kubernetes Engine (GKE) and the Cloud TPU API. The documentation says the Cloud TPU API is no longer under active development and receives bug fixes and security updates only; for Compute Engine, Google recommends managing TPUs with GKE or migrating to a newer TPU version. It also lists manually approved quota in us-central2-b and no default quota there. That is a region-specific note, not a statement of availability or quota in every location; check the documentation for the target region and current access requirements before planning deployment.
