Qwen 3 235B A22B Instruct vs DeepSeek V3.1: GPU energy per million output tokens
On the index rows, DeepSeek V3.1 uses 2.52× the GPU energy per output token of Qwen 3 235B A22B Instruct on the B200 (168.4 against 66.7 Wh/M, on eight cards and four cards at running batches of 3,008 and 3,765), GPU only, each at the most energy-efficient configuration the ML.ENERGY Leaderboard v3.0 measured for it (data compiled 16 February 2026). Qwen 3 235B A22B Instruct has 235 B parameters, 22 B active per token; DeepSeek V3.1 has 671 B parameters, 37 B active per token. Part of each gap is the sweep rather than the model: the two rows of a pair differ in card count and running batch, and the table states both.

Each ratio compares the two models' index rows on the same GPU: the lowest-energy configuration the leaderboard measured for each, at or under 500 ms median inter-token latency. The ratio is the second model's energy per token over the first's, so a figure under 1 means the second model's row is the lower one. Card count and running batch differ between the rows and are shown in the table.
The rows
Index rows on every GPU both models share
| GPU | Model | Cards | Precision | Running batch | GPU W | Tokens / s | Wh / M | Output tokens | Wh per answer | kg CO2e / bn tokens, world grid |
|---|---|---|---|---|---|---|---|---|---|---|
| B200 | Qwen 3 235B A22B Instruct | 4 × B200 | BF16 | 3,765 | 3,196 | 13,303 | 66.7 | 874 | 0.058 | 31.6 |
| B200 | DeepSeek V3.1 | 8 × B200 | FP8 | 3,008 | 5,470 | 9,021 | 168.4 | 842 | 0.142 | 79.7 |
Running batch is the average number of requests the server was decoding at once over the steady-state window (vLLM's num_requests_running). GPU W is the measured average power summed across the cards. Wh per answer is Wh/M times the row's own average output length. Carbon uses the world average grid, 473 gCO2e per kWh (Ember, 2024); the grid pages price every model on each listed grid. Model names link to every measured configuration.
What explains it
Two mixture-of-experts sizes
Two mixture-of-experts models of different total size: Qwen 3 235B A22B Instruct activates 22 B of 235 B parameters per token, DeepSeek V3.1 37 B of 671 B. Weights read per token scale with the active parameters (1.7× here), memory with the total (2.9×), so the larger model needs more cards to hold its experts and spreads each token's work across them. On the B200 the rows sit on four cards (Qwen 3 235B A22B Instruct) and eight cards (DeepSeek V3.1), at running batches of 3,765 (Qwen 3 235B A22B Instruct) and 3,008 (DeepSeek V3.1). The index row ratio on the B200 is 2.52×, between the active-parameter gap and the total-parameter gap.
Load still moves the number more than either model does: Qwen 3 32B on 2 × H100 spans 7.1× between a running batch of 8 and 256 on the same cards, which is wider than the gap on this page. Pick the model for the task, then run it busy. The running batch and floor entries define the terms.
Questions
Asked about Qwen 3 235B A22B Instruct against DeepSeek V3.1
Is Qwen 3 235B A22B Instruct more energy-efficient than DeepSeek V3.1?
Yes, on these rows: on the ML.ENERGY Leaderboard's index rows, DeepSeek V3.1 uses 2.52× the GPU energy per output token of Qwen 3 235B A22B Instruct on the B200 (168.4 against 66.7 Wh per million output tokens). These are floors at high load, GPU only, and the two rows of a pair differ in card count and running batch.
How much more energy does DeepSeek V3.1 use per million tokens than Qwen 3 235B A22B Instruct?
The index rows differ by 101.7 Wh/M on the B200 (101.7 kWh per billion tokens). Per answer, at each row's own average output length, Qwen 3 235B A22B Instruct costs 0.058 Wh on the B200 and DeepSeek V3.1 0.142 Wh on the B200.
Does the larger mixture-of-experts model cost more energy per token?
On the B200 index rows, yes: DeepSeek V3.1 (37 B active of 671 B) uses 2.52× the GPU energy per output token of Qwen 3 235B A22B Instruct (22 B active of 235 B), 168.4 against 66.7 Wh/M, on 8 and 4 cards at running batches of 3,008 and 3,765. Active parameters set the work per token; total parameters set the cards.
Why are the two rows not like for like?
The leaderboard sweeps each model separately: card count, the cap on requests in flight and the precision are chosen per model, and the running batch actually reached differs. On the B200 the rows here ran on 4 and 8 cards at running batches of 3,765 and 3,008. The ratio compares the best measured row on each side, not a matched run; every configuration is on the model pages and in the API, so any pair can be re-cut at a matched cap or running batch.
Where do these figures come from?
The ML.ENERGY Leaderboard v3.0 (data compiled 16 February 2026, retrieved 26 September 2026), Text Conversation task, GPU energy measured with Zeus under vLLM on H100 80GB HBM3 and B200 servers; each row is the lowest-energy configuration for its model and GPU at or under 500 ms median inter-token latency. Carbon per billion tokens multiplies the row by the world average grid intensity, 473 gCO2e per kWh (Ember, 2024).

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.
