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.

What the numbers mean
What the memory subsystem means for AI
Memory
4 GB
Bandwidth
26 GB/s
Largest model
DeciLM 6B
At 4 GB of LPDDR4 the Jetson Nano is limited to the smaller end of the catalogue. About 3.6 GB is actually available to a runtime, and a model has to fit entirely inside it before generating anything at all.
At 26 GB/s across a 64-bit bus, bandwidth is this card's real constraint. Every token requires reading the entire model out of memory, so a large model will feel slow here even when it fits.
The figure is the memory clock — 1.6 GHz here — multiplied by the bus width. It is why core counts predict generation speed so poorly.
Put together, the largest model that fits is DeciLM 6B at 5.7B, running Q3_K_M and producing around 4.4 tokens per second.
The chip and how it was built
The Jetson Nano is built on the GM20B graphics processor, using NVIDIA's Maxwell 2.0 architecture, as part of the Tegra(Maxwell) generation.
The chip is manufactured by TSMC, on a 20 nm process, with a die measuring 118 mm², holding 2 billion transistors. A smaller process generally means more performance for the same power, though for language models it matters far less than the memory subsystem.
It was released in March 2019, roughly 7 years ago. Inference software support tends to follow hardware by a year or two, so a card of this age generally has mature, well-optimised code paths available to it.
Compute throughput, and why it matters less than it looks
FP16
471.6 GFLOPS
FP64
7.4 GFLOPS
On paper the Jetson Nano reaches 471.6 GFLOPS at half precision and 235.8 GFLOPS at single precision. These are peak figures no real workload sustains, and generating text reaches only a small fraction of them — decoding is limited by memory rather than arithmetic, which is why a card can look enormously powerful here and still produce tokens at an ordinary rate.
Double-precision throughput is 7.4 GFLOPS. It has no bearing on running a language model — no inference runtime uses it — but it separates datacentre parts from consumer ones, since the latter deliberately restrict it.
Clocks run from 640 MHz at base to 921 MHz boosted. Worth far less here than on a gaming benchmark: raising the clock speeds up the arithmetic, and the arithmetic is not what generation is waiting on.
Cache and processing units
The Jetson Nano has 48 KB of L1 cache, backed by 0.25 MB of L2. Cache absorbs a share of the memory traffic that would otherwise hit the main bus, which is the one place on this page where a number other than bandwidth quietly affects generation speed — a large L2 lets more of the working set stay close to the cores.
There are 128 shading units, 16 texture mapping units, and 16 render output units. These drive graphics workloads and contribute to prompt processing, but they sit idle for much of the time a model spends generating a reply.
Power, size and installation
Power draw
10 W
The Jetson Nano is rated at 10 W. Running a language model keeps a card busy in bursts rather than continuously — it draws hard while generating and idles between requests — so sustained draw over a working day is usually well below the rated figure.
The board occupies a igp, measuring 70 mm long. Worth checking against the case and power supply already in the machine, since the largest cards need considerably more of both than a typical desktop provides.
It connects over PCIe 2.0 x4. The interface governs how quickly a model is loaded from disk into the card, not how fast it runs once there, so a narrower link costs a few seconds at startup and nothing thereafter.

Step by step
How to work out the tokens per second of a Jetson Nano
You do not have to calculate anything by hand — the gputps.com calculator on this page has already worked it out for every model this card can hold. Reading off the answer takes six steps.
-
01
Search for the model you want
The table lists 97 models this Jetson Nano can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Match the context to your work
Longer conversations cost memory on top of the weights. With 4 GB to work in, that is frequently the difference between a model fitting and not.
-
03
Pin the comparison to one quality level
Each model is shown at the best compression this card can hold. A minimum quality hides the ones that only fit by being squeezed further than you would accept.
-
04
Read the speed and the range
Each speed is an estimate for a single conversation, with a range beneath it — 9.2 tok/s on Gemma 3 QAT 1B at the top end here. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Read the fit verdict last
The fit column separates models that just fit from those with room to spare — worth checking against the card's 4 GB before settling on one.
-
06
Open the model to compare cards
Every model name in the table links to its own page, which runs the same calculation across every card we hold. That is where you see whether the Jetson Nano is the right buy for it or merely a card that fits.
Answers
Jetson Nano — common questions
Is the Jetson Nano good for running local AI models?
Its memory limits it to smaller models though its bandwidth means generation will feel slow on larger models. In total it runs 97 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a Jetson Nano run a model that does not fit in its memory?
It can be split, with the overflow held in system memory — but that part drags the whole thing down, and none of the 4 GB figures on this page assume it.
Would two Jetson Nano cards be twice as fast?
Pairing Jetson Nano cards buys headroom rather than pace: 8 GB of combined memory, at roughly the same generation speed as one.
What AI models can a Jetson Nano run?
97 of the 679 open-weight language models we track fit on a Jetson Nano and can be run locally on it. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.
What is the largest AI model a Jetson Nano can run?
The largest model in our catalogue that fits on a Jetson Nano is DeciLM 6B at 5.7B parameters, compressed to Q3_K_M. It generates roughly 4.4 tokens per second and needs about 3.5 GB of the card's memory.
How many tokens per second does a Jetson Nano produce?
It depends on the model. On a Jetson Nano the fastest model we track is Gemma 3 QAT 1B at about 9.2 tokens per second, while larger models run proportionally slower because each token requires reading the whole model out of memory once. Speeds are estimates for a single conversation at a time.
How much memory does a Jetson Nano have?
A Jetson Nano has 4 GB of LPDDR4 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 3.6 GB available for a model and its conversation.
What is the memory bandwidth of a Jetson Nano?
The Jetson Nano has 26 GB/s of memory bandwidth, across a 64-bit memory bus. This is the single best predictor of how fast it generates text, because producing each token means reading the entire model out of memory once.
What type of memory does a Jetson Nano use?
It uses LPDDR4 clocked at 1.6 GHz. HBM types are found on datacentre accelerators and carry far more bandwidth than the GDDR used on desktop cards, which is why they generate tokens considerably faster at the same capacity.
Who makes the Jetson Nano?
The Jetson Nano is a NVIDIA product, with the chip manufactured by TSMC, on a 20 nm process.
When was the Jetson Nano released?
The Jetson Nano was released in March 2019.
How much power does a Jetson Nano use?
The Jetson Nano has a rated board power of 10 W. Generating text draws hard in bursts and idles between requests, so average consumption over a working session is normally well below the rated figure.
How much cache does a Jetson Nano have?
The Jetson Nano has 48 KB of L1 cache, and 0.25 MB of L2 cache. Cache absorbs part of the memory traffic that would otherwise reach the main bus, so a larger L2 gives a modest lift to generation speed beyond what bandwidth alone predicts.
What are the TFLOPS of a Jetson Nano?
The Jetson Nano is rated at 471.6 GFLOPS at half precision and 235.8 GFLOPS at single precision. These are peak arithmetic ceilings rather than achievable rates, and text generation reaches only a small fraction of them because it is limited by memory bandwidth instead.
Does the Jetson Nano support CUDA?
Yes. The Jetson Nano reports CUDA compute capability 5.3, which predates tensor cores. Capability 7.0 and above has tensor cores, which modern inference software uses; below that it falls back to slower code paths for quantised models.
What bus interface does the Jetson Nano use?
It uses PCIe 2.0 x4. This governs how fast a model is loaded onto the card rather than how fast it runs once loaded, so it costs a few seconds at startup and nothing during generation.
The other direction
Looking at it from the other side?
This page starts from the hardware. If you already know which model you want and need to know what it takes to run it, start from the model instead.
