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.

Memory
94 GB
Bandwidth
3,940 GB/s
Largest model
dots.llm1
With 94 GB of HBM3, the H100 NVL 94 GB is in the class of hardware that holds the largest open-weight models without splitting them across machines. Roughly 84.6 GB of that is reachable by an inference runtime once the driver takes its share.
Its 3,940 GB/s across a 6,016-bit bus is at the top of what exists. Since each token means reading the whole model out of memory once, that translates almost directly into generation speed — this card is bandwidth-rich enough that model size stops being the limiting factor long before the bus does.
That comes from a 1.31 GHz memory clock across the bus width above. 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 dots.llm1 at 142B, running IQ4_XS and producing around 28.9 tokens per second.
The chip and how it was built
The H100 NVL 94 GB is built on the GH100 graphics processor, using NVIDIA's Hopper architecture, as part of the Server Hopper(Hxx) generation.
The chip is manufactured by TSMC, on a 5 nm process, with a die measuring 814 mm², holding 80 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 2023, roughly 3 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

241.3 TFLOPS
FP64
30.2 TFLOPS
Tensor cores
528
On paper the H100 NVL 94 GB reaches 241.3 TFLOPS at half precision and 60.3 TFLOPS 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 30.2 TFLOPS. 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 528 tensor cores across 132 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 1.08 GHz at base to 1.79 GHz 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 H100 NVL 94 GB has 250 KB of L1 cache, backed by 50 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 16,896 shading units, 528 texture mapping units, and 24 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
400 W
The H100 NVL 94 GB is rated at 400 W, with a 800 W power supply suggested for the whole system. 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 dual-slot, measuring 267 mm long, and needs 8-pin EPS. 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 5.0 x16. 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 H100 NVL 94 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
Find the model in the table
The table lists 609 models this H100 NVL 94 GB 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
Set the context to your real working length. Short questions cost almost nothing; a long document can consume a large share of the card's 94 GB.
-
03
Choose how far you will compress
Compression is what lets bigger models fit. The quality control drops any model that needs more of it than you are willing to give.
-
04
Take the range as the answer
The figures are calculated, not measured. 1,669 tok/s on Gemma 3 QAT 1B is the fastest result on this card, and like every row it carries a range that reflects how much the runtime matters.

Answers
H100 NVL 94 GB — common questions
How much cache does a H100 NVL 94 GB have?
The H100 NVL 94 GB has 250 KB of L1 cache, and 50 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 H100 NVL 94 GB?
The H100 NVL 94 GB is rated at 241.3 TFLOPS at half precision and 60.3 TFLOPS 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.
How many tensor cores does a H100 NVL 94 GB have?
The H100 NVL 94 GB has 528 tensor cores across 132 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.
Does the H100 NVL 94 GB support CUDA?
Yes. The H100 NVL 94 GB reports CUDA compute capability 9.0. 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 H100 NVL 94 GB use?
It uses PCIe 5.0 x16. 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.
Is the H100 NVL 94 GB good for running local AI models?
Its memory is large enough for models most desktop hardware cannot touch and its bandwidth puts it among the fastest hardware available for generation. In total it runs 609 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a H100 NVL 94 GB run a model that does not fit in its memory?
Only partly. Layers beyond the 94 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 H100 NVL 94 GB cards be twice as fast?
Pairing H100 NVL 94 GB cards buys headroom rather than pace: 188 GB of combined memory, at roughly the same generation speed as one.
What AI models can a H100 NVL 94 GB run?
609 of the 679 open-weight language models we track fit on a H100 NVL 94 GB 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 H100 NVL 94 GB can run?
The largest model in our catalogue that fits on a H100 NVL 94 GB is dots.llm1 at 142B parameters, compressed to IQ4_XS. It generates roughly 28.9 tokens per second and needs about 78.3 GB of the card's memory.
How many tokens per second does a H100 NVL 94 GB produce?
It depends on the model. On a H100 NVL 94 GB the fastest model we track is Gemma 3 QAT 1B at about 1,669 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.
Can a H100 NVL 94 GB run a 7B model?
Yes. For example a H100 NVL 94 GB runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 249 tokens per second.
Can a H100 NVL 94 GB run a 13B model?
Yes. For example a H100 NVL 94 GB runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 579 tokens per second.
Can a H100 NVL 94 GB run a 30B model?
Yes. For example a H100 NVL 94 GB runs ERNIE-4.5-VL-28B-A3B at Q8_0, using about 29.2 GB of memory and generating around 331 tokens per second.
Can a H100 NVL 94 GB run a 70B model?
Yes. For example a H100 NVL 94 GB runs Qwen3-Coder-Next at Q8_0, using about 80.7 GB of memory and generating around 116 tokens per second.
How much memory does a H100 NVL 94 GB have?
A H100 NVL 94 GB has 94 GB of HBM3 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 84.6 GB available for a model and its conversation.
What is the memory bandwidth of a H100 NVL 94 GB?
The H100 NVL 94 GB has 3,940 GB/s of memory bandwidth, across a 6,016-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 H100 NVL 94 GB use?
It uses HBM3 clocked at 1.31 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 H100 NVL 94 GB?
The H100 NVL 94 GB is a NVIDIA product, with the chip manufactured by TSMC, on a 5 nm process.
When was the H100 NVL 94 GB released?
The H100 NVL 94 GB was released in March 2023.
How much power does a H100 NVL 94 GB use?
The H100 NVL 94 GB has a rated board power of 400 W, and a 800 W system power supply is suggested. Generating text draws hard in bursts and idles between requests, so average consumption over a working session is normally well below the rated figure.
