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.

Fastest

NVIDIA Isaac GR00T N1.5 3B is small enough at 3B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.
The entry point is the Tesla C1080: 4 GB of memory, Q6_K compression, roughly 17.9 tokens per second.
A B200 is the fastest we calculate for it: about 1,129 tokens per second, from 8,000 GB/s of memory bandwidth.
What this model is
NVIDIA Isaac GR00T N1.5 3B was published by NVIDIA, in United States of America, in May 2025. It comes out of industry.
It works in Robotics, Vision, Language, and is recorded as doing robotic manipulation, Animal (human/non-human) imitation, Instruction interpretation.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold. It is published under the nvidia organisation on Hugging Face.
What decides the speed
The median result is around 35.8 tokens per second; 780 cards produce text faster than most people read it.
It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.
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.
Step by step
How to choose a GPU for NVIDIA Isaac GR00T N1.5 3B
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
Look at what NVIDIA Isaac GR00T N1.5 3B actually needs — around 3.2 GB at Q6_K. No amount of processing power compensates for a card that cannot hold it.
-
02
Decide how long your conversations run
Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason NVIDIA Isaac GR00T N1.5 3B stops fitting a card that seemed fine.
-
03
Decide how much compression you will accept
Each card runs the least-compressed copy it can hold — Q6_K on the smallest card that fits. Setting a floor drops the cards that only manage NVIDIA Isaac GR00T N1.5 3B by squeezing it further than you would want.
-
04
Sort by speed
The speed ordering for NVIDIA Isaac GR00T N1.5 3B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 1,129 tok/s.
-
05
Look at the headroom, not just the fit
A tight fit runs NVIDIA Isaac GR00T N1.5 3B but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
-
06
Check the card from the other side
Following a card through to its own page shows every other model it can hold, which is the question that follows once NVIDIA Isaac GR00T N1.5 3B is settled.
Answers
NVIDIA Isaac GR00T N1.5 3B — common questions
When was NVIDIA Isaac GR00T N1.5 3B released?
NVIDIA Isaac GR00T N1.5 3B was published in May 2025.
What is NVIDIA Isaac GR00T N1.5 3B used for?
NVIDIA Isaac GR00T N1.5 3B works in Robotics, Vision, Language, and is recorded as handling robotic manipulation, Animal (human/non-human) imitation, Instruction interpretation. These are the areas it was designed around; they describe intent rather than a hard boundary.
Where can I download NVIDIA Isaac GR00T N1.5 3B?
Its weights are published under the nvidia organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.
Can I run NVIDIA Isaac GR00T N1.5 3B if it does not fit in my GPU?
Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down. Our figures for NVIDIA Isaac GR00T N1.5 3B assume it is fully resident.
Would two GPUs run NVIDIA Isaac GR00T N1.5 3B faster?
A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run NVIDIA Isaac GR00T N1.5 3B alone, the case for pairing is weak.
Why does the quantisation differ between cards for NVIDIA Isaac GR00T N1.5 3B?
Because capacity varies, so does how hard NVIDIA Isaac GR00T N1.5 3B has to be squeezed — 2 distinct levels appear in the table above. Set a minimum quality to compare at one.
How accurate are these NVIDIA Isaac GR00T N1.5 3B speed estimates?
These are estimates with real error bars. The fastest result here, 678–1,807 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.
What GPU do I need to run NVIDIA Isaac GR00T N1.5 3B?
The smallest card in our catalogue that holds NVIDIA Isaac GR00T N1.5 3B is the Tesla C1080, with 4 GB of memory. It runs the model at Q6_K using about 3.2 GB, and produces roughly 17.9 tokens per second. 818 cards in total can run it.
How fast is NVIDIA Isaac GR00T N1.5 3B on a GPU?
It depends on the card. The quickest we calculate is a B200 at about 1,129 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 780 of the cards that can run NVIDIA Isaac GR00T N1.5 3B clear that.
How much VRAM does NVIDIA Isaac GR00T N1.5 3B need?
About 3.2 GB at Q6_K compression, 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.
Can I run NVIDIA Isaac GR00T N1.5 3B on a 8 GB GPU?
Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 3.9 GB and generating roughly 210 tokens per second — a comfortable fit.
Can I run NVIDIA Isaac GR00T N1.5 3B on a 12 GB GPU?
Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 3.9 GB and generating roughly 129 tokens per second — a comfortable fit.
Can I run NVIDIA Isaac GR00T N1.5 3B on a 16 GB GPU?
Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 3.9 GB and generating roughly 160 tokens per second — a comfortable fit.
Can I run NVIDIA Isaac GR00T N1.5 3B on a 24 GB GPU?
Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 3.9 GB and generating roughly 189 tokens per second — a comfortable fit.
Is NVIDIA Isaac GR00T N1.5 3B open source?
Its weights are published, so NVIDIA Isaac GR00T N1.5 3B 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.
How many parameters does NVIDIA Isaac GR00T N1.5 3B have?
NVIDIA Isaac GR00T N1.5 3B has 3B parameters. 3B. 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.
Who created NVIDIA Isaac GR00T N1.5 3B?
NVIDIA Isaac GR00T N1.5 3B was published by NVIDIA, based in United States of America, categorised as industry.
