There is no source-backed universal winner: first check whether the model, runtime, and KV cache fit in usable memory, then benchmark the same workload for latency, throughput, and total cost.
For Gemma 4 specifically, Google estimates Q4_0 loading memory at 6.7 GB for 12B, 14.4 GB for 26B A4B, and 17.5 GB for 31B. One TPU v5e chip has 16 GB HBM, so those figures are a memory screen—not a guarantee of serving fit or performance.

What fits on one TPU v5e chip?
A single Cloud TPU v5e chip has 16 GB of HBM. Google’s Gemma 4 overview publishes approximate accelerator-memory estimates for Q4_0 models, including 20% overhead for loading additional things. The estimates exclude software runtime and context-window/KV-cache memory, and Google cautions that actual numbers may vary with inference tool and environment. See Google’s Gemma 4 overview and Cloud TPU v5e specifications.

| Gemma 4 model | Q4_0 approximate load memory | Comparison with 16 GB on one v5e chip |
|---|---|---|
| E2B | 2.9 GB | Nominal room remains for runtime and context; actual fit depends on the serving stack and workload. |
| E4B | 4.5 GB | Nominal room remains for runtime and context; actual fit depends on the serving stack and workload. |
| 12B | 6.7 GB | Nominal room remains for runtime and context; actual fit depends on the serving stack and workload. |
| 26B A4B | 14.4 GB | Tight before adding excluded runtime and context memory. |
| 31B | 17.5 GB | Above one chip’s nominal HBM capacity. |
These are Google’s approximate Gemma 4 Q4_0 loading estimates, not measured serving results. In particular, 26B A4B is a mixture-of-experts model, but its 4B active-per-token count does not reduce its loading footprint to that of a 4B model: Google says all 26 billion parameters must be loaded for fast routing and inference. Longer context increases KV-cache memory. The figures apply to this Gemma 4 table; for another Gemma generation, quantization format, or artifact, use that model’s own estimate and test it in the intended runtime.

Hardware alternatives to evaluate
The alternatives below differ in memory, deployment model, and software route. The cited Google Cloud recommendations are not head-to-head Gemma benchmarks, so use them to shortlist candidates rather than predict speed or cost.
NVIDIA L4 cloud GPU
Google Cloud’s GKE accelerator guidance identifies the L4 in the G2 machine series as a cost-effective option for small-model inference and lists 24 GB per GPU. That is more nominal accelerator memory than one v5e chip, but the cited guidance does not establish that L4 runs quantized Gemma faster or cheaper. It is worth evaluating when the model fits its memory budget and a GPU-based cloud deployment suits the application. See Google Cloud’s GKE GPU guidance.
NVIDIA RTX Pro 6000 cloud GPU
The same guidance lists RTX Pro 6000 in the G4 machine series with 96 GB per GPU, describing it as a cost-effective option for models under 30B parameters. It also notes direct GPU peer-to-peer communication for single-host multi-GPU inference. This makes it a candidate when additional per-GPU memory or multi-GPU expansion matters; the guidance does not provide a Gemma-specific comparison or establish retail price and availability.

NVIDIA A100 or H100 cloud configurations
Google Cloud categorizes A100 and H100 for single-host large-model inference. Its guidance describes A100 as suitable for most models that fit on one node and gives a node-level ceiling of up to 640 GB total memory; it gives the same stated node-level ceiling for H100. Those are machine-level figures, not memory on one card, and do not show that a particular Gemma artifact will achieve a particular speed.
Local CPU, consumer GPU, or Apple Silicon
Google’s Gemma inference guide lists llama.cpp as a local option for CPU and Apple Silicon, alongside desktop and local runners such as LM Studio and Ollama, and Apple’s MLX framework. These routes can suit experimentation or local inference, but whether a model is practical depends on host RAM or VRAM, artifact, context length, and runtime. Google names Keras format, Safetensors, and GGUF as examples of Gemma formats; check that the selected engine supports the specific artifact before choosing hardware. See Google’s Gemma inference guide.
More TPU chips or another TPU generation
If staying with TPU is preferable, Google documents single-host v5e serving on 1-, 4-, and 8-chip slices. A 4- or 8-chip slice changes the one-chip constraint, but the appropriate configuration still depends on model placement, runtime, and workload. Google’s GKE guidance describes v6e as offering high value for transformer and text-to-image models; it does not provide a Gemma-specific v6e-versus-single-v5e benchmark.

Match the model artifact to the inference software
Hardware capacity is useful only if the selected serving stack can load and run the chosen quantized artifact. Google lists local choices including llama.cpp, LM Studio, Ollama, and MLX, and cloud or development frameworks including vLLM, Transformers, and Keras. Their presence in Google’s guidance does not mean every framework supports every Gemma quantization format in the same way. Confirm the exact model format, accelerator backend, and required features—such as the intended context length—before reserving capacity.
Recommended Free Tools
For TPU v5e, Google documents vLLM integration through its tpu-inference plugin for JAX and PyTorch models. Google’s v5e documentation also states: “The Cloud TPU API is no longer under active development and will receive bug fixes and security updates only.” It points users to Google Kubernetes Engine support. Check the current deployment route, quota, and location availability before planning a production service. See Cloud TPU v5e documentation and Google’s vLLM TPU integration guidance.
Benchmark alternatives on the workload you will run
Memory capacity alone cannot tell you which option is faster or cheaper. A fair comparison holds the model and serving conditions constant, then measures both performance and the complete deployment cost.
- Fix the workload. Use the same Gemma checkpoint, quantization format, prompts, output lengths, context limit, and batch or concurrency target on each candidate.
- Validate software support. Load the same artifact in the intended inference engine and confirm that required model features work; do not assume a format or backend is interchangeable.
- Measure memory under serving conditions. Record peak accelerator memory with the target context and KV cache, not just the model-loading estimate. Test the concurrency you expect to serve.
- Record performance. Measure time to first token, steady-state generation throughput, and throughput across concurrent requests. Keep quality checks consistent so a speed comparison does not conceal a changed output configuration.
- Calculate deployment cost. For cloud options, include the machine shape, region, utilization, orchestration, and idle capacity required to meet the same service target.
Google’s documentation supplies accelerator categories, specifications, and model-loading estimates, but not a controlled quantized-Gemma benchmark comparing one v5e chip with these alternatives. A claim that one option is faster or cheaper therefore needs measurements for the intended deployment rather than an inference from peak compute or memory alone.
TPU v5e planning details
Google documents the one-chip v5e machine type as ct5lp-hightpu-1t. Its published per-chip specifications are 16 GB HBM, 197 TFLOPs peak BF16 compute, and 393 TOPs peak Int8 compute. These are peak specifications, not measured Gemma throughput. Serving requires a Google Cloud account and project, plus sufficient serving quota; v5e serving quota is separate from training quota. Verify location availability and quota for the intended deployment before relying on a specific TPU shape.
