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
128 GB
Bandwidth
273 GB/s
Largest model
Solar Open2 250B
With 128 GB of LPDDR5X, the GB10 is in the class of hardware that holds the largest open-weight models without splitting them across machines. Roughly 115.2 GB of that is reachable by an inference runtime once the driver takes its share.
At 273 GB/s across a 256-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.
That comes from a 1.07 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.
The biggest thing it holds is Solar Open2 250B (250.3B) at Q3_K_M compression, for about 6.9 tokens per second.
The chip and how it was built
The GB10 is built on the GB20B graphics processor, using NVIDIA's Blackwell 2.0 architecture, as part of the Server Blackwell(Bxx) generation.
The chip is manufactured by TSMC, on a 5 nm process. 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 October 2025. 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
29.7 TFLOPS
FP64
464.3 GFLOPS
Tensor cores
384
On paper the GB10 reaches 29.7 TFLOPS at half precision and 29.7 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 464.3 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 384 tensor cores across 48 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 1.67 GHz at base to 2.42 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 GB10 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 6,144 shading units, 384 texture mapping units, and 48 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
140 W
The GB10 is rated at 140 W, with a 300 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 igp, measuring 150 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 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.

The fastest AI models on a GB10
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 GB10
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
All 624 models the GB10 handles are already listed. The search box takes a name or a size such as 27b, which matches on parameter count.
-
02
Match the context to your work
Drag the slider to the conversation length you plan to work at. The cache grows with the conversation, and on 128 GB it is often what pushes a large model over the edge.
-
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
Look at the range, not just the number
The figures are calculated, not measured. 116 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.
-
05
Check the headroom before you decide
The fit column separates models that just fit from those with room to spare — worth checking against the card's 128 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 GB10 is the right buy for it or merely a card that fits.
Answers
GB10 — common questions
How much memory does a GB10 have?
A GB10 has 128 GB of LPDDR5X memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 115.2 GB available for a model and its conversation.
What is the memory bandwidth of a GB10?
The GB10 has 273 GB/s of memory bandwidth, across a 256-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 GB10 use?
It uses LPDDR5X clocked at 1.07 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 GB10?
The GB10 is a NVIDIA product, with the chip manufactured by TSMC, on a 5 nm process.
When was the GB10 released?
The GB10 was released in October 2025.
How much power does a GB10 use?
The GB10 has a rated board power of 140 W, and a 300 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.
How much cache does a GB10 have?
The GB10 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 GB10?
The GB10 is rated at 29.7 TFLOPS at half precision and 29.7 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 GB10 have?
The GB10 has 384 tensor cores across 48 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 GB10 support CUDA?
Yes. The GB10 reports CUDA compute capability 12.1. 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 GB10 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 GB10 good for running local AI models?
Its memory is large enough for models most desktop hardware cannot touch though its bandwidth means generation will feel slow on larger models. In total it runs 624 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a GB10 run a model that does not fit in its memory?
Offloading past the card's 128 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
Would two GB10 cards be twice as fast?
Pairing GB10 cards buys headroom rather than pace: 256 GB of combined memory, at roughly the same generation speed as one.
What AI models can a GB10 run?
624 of the 679 open-weight language models we track fit on a GB10 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 GB10 can run?
The largest model in our catalogue that fits on a GB10 is Solar Open2 250B at 250.3B parameters, compressed to Q3_K_M. It generates roughly 6.9 tokens per second and needs about 106.6 GB of the card's memory.
How many tokens per second does a GB10 produce?
It depends on the model. On a GB10 the fastest model we track is Gemma 3 QAT 1B at about 116 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 GB10 run a 7B model?
Yes. For example a GB10 runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 17.3 tokens per second.
Can a GB10 run a 13B model?
Yes. For example a GB10 runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 40.2 tokens per second.
Can a GB10 run a 30B model?
Yes. For example a GB10 runs ERNIE-4.5-VL-28B-A3B at Q8_0, using about 29.2 GB of memory and generating around 23.0 tokens per second.
Can a GB10 run a 70B model?
Yes. For example a GB10 runs Qwen3-Coder-Next at Q8_0, using about 80.7 GB of memory and generating around 8.0 tokens per second.
