Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

The extremes

The ten fastest GPUs that run Nemotron 3.5 Lightning

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run Nemotron 3.5 Lightning

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

The hardware side

Minimum card

Xeon Phi 7120P

Memory needed

13.7 GB

Fastest

627 tok/s

Nemotron 3.5 Lightning reaches a parameter count of 30B. That lands in the range a serious desktop card can handle once the weights are compressed. The number of cards we track that can run it: 241.

At the low end it is handled by Xeon Phi 7120P, with a memory capacity of 16 GB, running it at a compression of Q3_K_M and producing around 48.4 tokens per second.

The quickest result comes from B200, generating roughly 627 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

Nemotron 3.5 Lightning was published by NVIDIA, in the country recorded as United States of America, during August 2026. The publishing organisation is categorised as industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded. On Hugging Face it is published under the organisation nvidia.

Reading the throughput figures

Across every card that can run it, the middle of the range sits at 95.1 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 239 of them.

This is a mixture-of-experts model, which routes each token through only part of itself. It therefore generates far faster than its total size suggests — while still needing every parameter resident in memory, so it is quick without being cheap to hold.

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

What went into building it

It was trained on a corpus of about 20,000,000,000,000 tokens of text.

Step by step

How to choose a GPU for Nemotron 3.5 Lightning

The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.

01

Start from the memory column

Start from what it actually needs, which is the requirement of Nemotron 3.5 Lightning, needing around 13.7 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
02

Decide how long your conversations run

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Nemotron 3.5 Lightning.
03

Set a quality floor

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of Q3_K_M on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Compare tokens per second, not specifications

Sort by speed to see how cards rank for Nemotron 3.5 Lightning. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 627 tok/s.
05

Check the fit verdict before buying

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of Nemotron 3.5 Lightning. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
06

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Nemotron 3.5 Lightning.

Answers

Nemotron 3.5 Lightning — common questions

Nemotron 3.5 Lightning— why does the quantisation differ between cards?

Each card is shown running the least-compressed copy it can hold. The number of distinct compression levels across the cards that fit it: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Nemotron 3.5 Lightning— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 376–1,004 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Nemotron 3.5 Lightning— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Xeon Phi 7120P, with a memory capacity of 16 GB. It runs the model at a compression of Q3_K_M using about 13.7 GB, and produces roughly 48.4 tokens per second. The number of cards able to run it in total: 241.

Nemotron 3.5 Lightning— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 627 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 239.

Nemotron 3.5 Lightning— how much VRAM does it need?

It needs about 13.7 GB at a compression of Q3_K_M, which is what the smallest card that runs it uses. Less compression needs more: the figures in the memory column above are recalculated for each card, because each one holds the least-compressed version it can.

Nemotron 3.5 Lightning— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q3_K_M, using about 13.7 GB and generating roughly 239 tokens per second. The fit is tight.

Nemotron 3.5 Lightning— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q5_K_M, using about 20.7 GB and generating roughly 188 tokens per second. The fit is tight.

Nemotron 3.5 Lightning— is it open source?

Its weights are published, so it can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

Nemotron 3.5 Lightning— how many parameters does it have?

It has a parameter count of 30B. 30B total, 3B active. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

Nemotron 3.5 Lightning— who created it?

It was published by NVIDIA, based in United States of America, an organisation categorised as industry.

Nemotron 3.5 Lightning— when was it released?

It was published in August 2026.

Nemotron 3.5 Lightning— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

Nemotron 3.5 Lightning— where can I download it?

Its weights are published on Hugging Face, under the organisation nvidia. We do not host model files — this site calculates what hardware is needed to run them.

Nemotron 3.5 Lightning— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. The nearest miss we calculate falls short by 6.4 GB. Every figure here assumes the whole model is resident on the card.

Nemotron 3.5 Lightning— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 241. So a second card is rarely the answer here.
