Qwen 3 30B A3B Instruct: GPU energy per million output tokens

Qwen 3 30B A3B Instruct serves a million output tokens for 15.7 Wh/M on 1 × B200 (running batch 1,023, median inter-token latency 89 ms) and 24.7 Wh/M on 2 × H100 (running batch 1,019, median inter-token latency 75 ms), GPU energy only, at the most energy-efficient configuration the ML.ENERGY Leaderboard measured. That is the floor: a lightly loaded server sits above it.

Model Qwen/Qwen3-30B-A3B-Instruct-2507, a mixture-of-experts model (3 B of 30 B parameters active per token), weights in BF16. Measured 31 configurations on B200 and H100. Data models/qwen-3-30b-a3b-instruct.json. Updated 27 September 2026.

Index row, B20015.7Wh/M1 × B200, BF16. Running batch 1,023, median ITL 89 ms, 601 W across the cards, 10,648 tokens a second.
Index row, H10024.7Wh/M2 × H100, BF16. Running batch 1,019, median ITL 75 ms, 1,123 W across the cards, 12,640 tokens a second.

GPU only, busy server. Every row is a floor. The number a buyer should ask for is the one measured on their own server at their own load. Unit: watt-hours per million output tokens (Wh/M); one Wh/M is 0.0036 joules per token.

Every configuration

Qwen 3 30B A3B Instruct at every measured load

On 2 × H100, Qwen 3 30B A3B Instruct runs from 228.6 Wh/M at a running batch of 8 to 24.7 Wh/M at 1,019, a fall of 9.3×, while the cards' draw rises 64 percent (from 684 to 1,123 W) and throughput rises 15.2× (from 831 to 12,640 tokens a second). Median inter-token latency stays at 75 ms or under up to the best row.

Cap is the configured maximum batch (vLLM's max_num_seqs). Running batch (avg) is the average number of requests the server was decoding at once over the steady-state window (vLLM's num_requests_running); queued requests are not counted. The highlighted row is the index row for that GPU. Wh/M is derived from the source's joules per output token; prompt processing is included.

Two generations

H100 against B200

On the index rows, the H100 configuration uses 1.58× the energy per token of the B200 configuration: 24.7 Wh/M on 2 × H100 against 15.7 Wh/M on 1 × B200. The two rows were not swept alike: the H100 row holds a running batch of 1,019 on 2 cards and the B200 row 1,023 on 1, so part of the gap is the sweep, not the silicon. The full comparison across 14 models is on the index.

Carbon

Same tokens, different grid

A billion output tokens of Qwen 3 30B A3B Instruct on 1 × B200 at its index row carries about 10.8 kg CO2e of GPU-side emissions on the Saudi grid (692 gCO2e per kWh, Ember 2024) and 0.5 kg on the Norwegian grid (30). Energy per token does not change with geography; carbon per token does.

Wh/M × gCO2e per kWh ÷ 1,000. Lifecycle emissions intensity: CO2e per kWh of net generation, built from per-technology lifecycle factors (IPCC AR5 WG3 Annex III midpoints, all gases at GWP-100), so upstream methane, supply chains and plant manufacture are included. Production-based: imports and grid losses are excluded. A location-based figure for comparing places, not a Scope 2 combustion factor to file as reported.

Questions

Asked about Qwen 3 30B A3B Instruct

How much energy does Qwen 3 30B A3B Instruct use per million output tokens?

Qwen 3 30B A3B Instruct uses 15.7 Wh of GPU energy per million output tokens on 1 × B200 and 24.7 Wh of GPU energy per million output tokens on 2 × H100 at the most energy-efficient configuration measured (ML.ENERGY Leaderboard v3.0, Text Conversation, data compiled 16 February 2026). Host, network, cooling and idle time are not counted, so it is a floor.

Is Qwen 3 30B A3B Instruct more energy-efficient on B200 or H100?

On the index rows, the H100 configuration uses 1.58× the energy per token of the B200 configuration: 24.7 Wh/M on 2 × H100 against 15.7 Wh/M on 1 × B200. Both are floors at high load.

How much does load change the energy per token of Qwen 3 30B A3B Instruct?

On 2 × H100, energy per token falls 9.3× between a running batch of 8 (228.6 Wh/M) and 1,019 (24.7 Wh/M), because the cards' power rises only 64 percent while throughput rises 15.2×. A server holding a handful of requests at a time sits at the top of that range.

What is the carbon footprint of a billion tokens of Qwen 3 30B A3B Instruct?

A billion output tokens of Qwen 3 30B A3B Instruct on 1 × B200 at its index row carries about 10.8 kg CO2e of GPU-side emissions on the Saudi grid (692 gCO2e per kWh, Ember 2024) and 0.5 kg on the Norwegian grid (30). Multiply the Wh/M figure by your own grid's intensity and divide by 1,000 for kilograms per billion tokens.

Is this the energy my Qwen 3 30B A3B Instruct deployment will use?

No. Every figure here is the lowest-energy configuration under the leaderboard's 500 ms median inter-token latency ceiling, on a busy server, GPU only. Your deployment sits above it, often several times above it; the configuration table shows how far. To get your own figure, follow the measurement protocol on the contribute page.

Where do these figures come from?

The ML.ENERGY Leaderboard v3.0 (The ML.ENERGY Initiative), released 1 December 2025, data compiled 16 February 2026, retrieved 26 September 2026: 31 stable configurations of Qwen 3 30B A3B Instruct measured with Zeus under vLLM on H100 80GB and B200 servers. Grid intensities are Ember's 2024 yearly figures. Lead Green recomputes every number from dated snapshots.

Where every figure came from

ML.ENERGY Leaderboard version 3.0 (released 1 December 2025; data compiled 16 February 2026; retrieved 26 September 2026), The ML.ENERGY Initiative, started at SymbioticLab, University of Michigan. Text Conversation task, 328 stable configurations. Energy per token is steady-state GPU energy divided by the output tokens generated in the window, measured with Zeus under vLLM 0.11.1 on H100 80GB HBM3 and B200 servers; energy per request is that figure times the average output length. Each index row is the lowest-energy configuration for its model and GPU at or under a 500 ms median inter-token latency, the leaderboard's own default ceiling, which no configuration reaches.
