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
Capacity and bandwidth
Memory
8 GB
Bandwidth
60 GB/s
Largest model
Baichuan 1-13B
Jetson Xavier NX 8 GB carries only 8 GB of LPDDR4X. That limits it to the smaller end of the catalogue, and a model has to fit entirely inside before it generates anything at all. A runtime actually gets about 7.2 GB.
Memory bandwidth reaches 60 GB/s across a bus of 128 bits. 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.
That comes from a memory clock of 1.87 GHz. Widening the bus and raising the clock are the two levers a manufacturer has, which is why a card with unremarkable cores can still generate quickly.
Put together, the largest model that fits is Baichuan 1-13B, 13.3B, compressed to Q3_K_M and generating around 5.1 tokens per second.
The chip and how it was built
Jetson Xavier NX 8 GB is built on the graphics processor GV10B, using the architecture Volta from NVIDIA, as part of the generation Tegra(Volta).
The chip is manufactured by TSMC, on a process of 12 nm, with a die measuring 350 mm², holding 9 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 May 2020, roughly 6.3361393111919 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
1.7 TFLOPS
FP64
422.4 GFLOPS
Tensor cores
48
On paper Jetson Xavier NX 8 GB reaches 1.7 TFLOPS at half precision, and 844.8 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 reaches 422.4 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.
The card carries 48 tensor cores across 6 streaming multiprocessors. These accelerate the matrix arithmetic at the heart of a transformer, and they are what make prompt processing — reading a long document before answering — dramatically faster than it would otherwise be.
Clocks run from a base of 854 MHz to a boost of 1.1 GHz. 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
Jetson Xavier NX 8 GB has an L1 cache of 128 KB, backed by an L2 cache of 0.25 MB. 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 384 shading units, 24 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
15 W
Jetson Xavier NX 8 GB is rated at 15 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 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 4.0 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.

Where this card produces tokens quickest. Smaller models dominate here, because generating each token means reading the whole model out of memory once.
Step by step
How to work out the tokens per second of a Jetson Xavier NX 8 GB
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
Start with the model, not the specification
The table lists 351 models this card 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. Against 8 GB that is frequently the difference between a model fitting and not.
-
03
Choose how far you will compress
By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.
-
04
Take the range as the answer
Each speed is an estimate for a single conversation, with a range beneath it. The top end here is 25.3 tok/s on Gemma 3 QAT 1B. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Check the headroom before you decide
The fit column separates models that just fit from those with room to spare — worth checking before settling on one, against an available 8 GB.
-
06
Open the model to compare cards
Each model page repeats this calculation for the whole catalogue. Worth a look before deciding: it shows what else runs the same model, alongside Jetson Xavier NX 8 GB.
Answers
Jetson Xavier NX 8 GB — common questions
Jetson Xavier NX 8 GB— is it 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 351 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Jetson Xavier NX 8 GB— can it run a model that does not fit in its memory?
It can be split, with the overflow held in system memory beyond the card's 8 GB sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. Every figure here assumes it is fully resident on the card.
Would two Jetson Xavier NX 8 GB cards be twice as fast?
Pairing them buys headroom rather than pace: 16 GB which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.
Jetson Xavier NX 8 GB— which AI models can it run?
351 of the 721 open-weight language models we track fit on this card and can be run locally. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.
Jetson Xavier NX 8 GB— what is the largest AI model it can run?
The largest model in our catalogue that fits is Baichuan 1-13B at 13.3B parameters, compressed to Q3_K_M. It generates roughly 5.1 tokens per second and needs about 7.2 GB of the card's memory.
Jetson Xavier NX 8 GB— how many tokens per second does it produce?
It depends on the model. The fastest model we track here is Gemma 3 QAT 1B at about 25.3 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.
Jetson Xavier NX 8 GB— can it run 7B models?
Yes. For example it runs Gemma 4 E4B at Q5_K_M, using about 7.0 GB of memory and generating around 10.0 tokens per second.
Jetson Xavier NX 8 GB— can it run 13B models?
Yes. For example it runs Gemma 4 12B at Q3_K_M, using about 6.5 GB of memory and generating around 5.7 tokens per second.
Jetson Xavier NX 8 GB— how much memory does it have?
This card has 8 GB of LPDDR4X. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 7.2 GB available for a model and its conversation.
Jetson Xavier NX 8 GB— what is its memory bandwidth?
Memory bandwidth reaches 60 GB/s across a bus of 128 bits. 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.
Jetson Xavier NX 8 GB— what type of memory does it use?
It uses LPDDR4X clocked at 1.87 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.
Jetson Xavier NX 8 GB— who makes it?
This is a product of NVIDIA, with the chip manufactured by TSMC, on a process of 12 nm.
Jetson Xavier NX 8 GB— when was it released?
It was released in May 2020.
Jetson Xavier NX 8 GB— how much power does it use?
Rated board power is 15 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.
Jetson Xavier NX 8 GB— how much cache does it have?
The L1 cache is 128 KB, and the L2 cache is 0.25 MB. 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.
Jetson Xavier NX 8 GB— what are its TFLOPS?
It is rated at 1.7 TFLOPS at half precision and 844.8 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.
Jetson Xavier NX 8 GB— how many tensor cores does it have?
It has 48 tensor cores across 6 streaming multiprocessors. They accelerate the matrix arithmetic a transformer is built from, which mainly speeds up processing a long prompt rather than producing the reply.
Jetson Xavier NX 8 GB— does it support CUDA?
Yes. It reports CUDA compute capability 7.2. 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.
Jetson Xavier NX 8 GB— what bus interface does it use?
It uses PCIe 4.0 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.
