Llama 3 70B on TPU v5p (per-chip, 95GB): Does It Fit, How Fast, What It Costs

Llama 3 70B at FP8 (E4M3) needs 70.6 GB for its weights and 92.1 GB in total at 8K context with 8 concurrent users. That means it fits on a single TPU v5p (per-chip, 95GB). Every figure is computed by tokcalc's open-source capacity model.

What changes as you add TPU v5p (per-chip, 95GB)s
Tensor-parallel degree vs VRAM, throughput, and cost. Cost scales linearly with GPU count; decode throughput scales near-linearly too, so cost per token stays roughly flat.

Frequently asked questions

Can Llama 3 70B run on TPU v5p (per-chip, 95GB)?

Yes. Llama 3 70B at FP8 (E4M3) needs 92.1 GB including the KV cache, and TPU v5p (per-chip, 95GB) has 95 GB — so it fits on a single GPU.

How fast is Llama 3 70B on TPU v5p (per-chip, 95GB)?

11.31 tokens/sec per stream and 135.7 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 5.16 s, and inter-token latency is 88.4 ms.

What does Llama 3 70B on TPU v5p (per-chip, 95GB) cost per million tokens?

$8.60 per 1M output tokens at 1× TPU v5p (per-chip, 95GB) ($4.20/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Llama 3 70B need on TPU v5p (per-chip, 95GB)?

70.6 GB for the weights at FP8 (E4M3), plus 21.5 GB of KV cache for 8 concurrent requests at 8K context — 92.1 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is TPU v5p (per-chip, 95GB) the right choice for Llama 3 70B?

It works. Compare $8.60 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 4080 16GB at $0.1031, and the fastest is 4× Cerebras CS-3 (WSE-3) at 45076 tok/s.
