Llama 4 Maverick 17B-128E (MoE, VLM) on L40S 48GB: Does It Fit, How Fast, What It Costs

Llama 4 Maverick 17B-128E (MoE, VLM) at AWQ 4-bit needs 220.0 GB for its weights and 232.9 GB in total at 8K context with 8 concurrent users. That means it needs 8× L40S 48GB. Every figure is computed by tokcalc's open-source capacity model.

8× L40S 48GB

L40S 48GB has no NVLink, so 8-way tensor parallelism runs over PCIe. tokcalc applies a flat 0.85× multi-GPU efficiency factor for this, which is realistic for NVLink-equipped datacenter cards but optimistic for PCIe scale-out — treat the throughput and cost figures for this configuration as an upper bound, and measure before committing.

What changes as you add L40S 48GBs
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 4 Maverick 17B-128E (MoE, VLM) run on L40S 48GB?

Yes, but it needs 8× L40S 48GB. At AWQ 4-bit the total footprint is 232.9 GB (220.0 GB of weights plus 12.9 GB of KV cache at 8K × 8 concurrent users), against 384 GB of available VRAM across 8 GPUs.

How fast is Llama 4 Maverick 17B-128E (MoE, VLM) on L40S 48GB?

359.4 tokens/sec per stream and 34505 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 793.0 ms, and inter-token latency is 2.8 ms.

What does Llama 4 Maverick 17B-128E (MoE, VLM) on L40S 48GB cost per million tokens?

$0.0451 per 1M output tokens at 8× L40S 48GB ($0.7000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Llama 4 Maverick 17B-128E (MoE, VLM) need on L40S 48GB?

220.0 GB for the weights at AWQ 4-bit, plus 12.9 GB of KV cache for 8 concurrent requests at 8K context — 232.9 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is L40S 48GB the right choice for Llama 4 Maverick 17B-128E (MoE, VLM)?

It works. Compare $0.0451 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 5090 32GB at $0.0155, and the fastest is 8× Cerebras CS-3 (WSE-3) at 798720 tok/s.
