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.

The extremes

The ten fastest GPUs that run MPT-30B

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run MPT-30B

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

What you need to run it

Minimum card

RTX A4500

Memory needed

17.1 GB

Fastest

113 tok/s

MPT-30B reaches a parameter count of 30B. That lands in the range a serious desktop card can handle once the weights are compressed. The number of cards we track that can run it: 132.

The least hardware that works is RTX A4500, with a memory capacity of 20 GB, running it at a compression of IQ4_XS and producing around 22.2 tokens per second.

Top of the range is B200, generating roughly 113 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

What this model is

MPT-30B was published by MosaicML, in the country recorded as United States of America, during June 2023. It comes out of an organisation categorised as industry.

It works in the domain of Language, and is recorded as performing the task of language generation, Code generation.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. On Hugging Face it is published under the organisation mosaicml.

What decides the speed

Across every card that can run it, the middle of the range sits at 22.0 tokens per second. Exceeding reading speed outright: 104 of them.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

Training and provenance

The training run consumed about 1.9 × 10²³ FLOP, on hardware recorded as NVIDIA H100 SXM5 80GB. That figure measures what producing the model cost, and has no bearing on how fast it answers.

It was trained on a corpus of about 1,050,000,000,000 tokens of text.

Step by step

How to choose a GPU for MPT-30B

The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.

01

Check what it needs before anything else

Start from what it actually needs, which is the requirement of MPT-30B, needing around 17.1 GB at a compression of IQ4_XS. No amount of processing power compensates for a card that cannot hold it.
02

Set the context length you will work at

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for MPT-30B.
03

Decide how much compression you will accept

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of IQ4_XS on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Sort by speed

Sort by speed to see how cards rank for MPT-30B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 113 tok/s.
05

Read the fit column last

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of MPT-30B. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
06

See what else that card runs

Following a card through to its own page shows every other model it can hold, which is the question that follows once you have settled on MPT-30B.

Answers

MPT-30B — common questions

MPT-30B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 68–181 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

MPT-30B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is RTX A4500, with a memory capacity of 20 GB. It runs the model at a compression of IQ4_XS using about 17.1 GB, and produces roughly 22.2 tokens per second. The number of cards able to run it in total: 132.

MPT-30B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 113 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 104.

MPT-30B— how much VRAM does it need?

It needs about 17.1 GB at a compression of IQ4_XS, 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.

MPT-30B— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q4_K_M, using about 18.8 GB and generating roughly 43.7 tokens per second. The fit is tight.

MPT-30B— is it open source?

Its weights are published, so it 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.

MPT-30B— how many parameters does it have?

It has a parameter count of 30B. 30B. 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.

MPT-30B— who created it?

It was published by MosaicML, based in United States of America, an organisation categorised as industry.

MPT-30B— when was it released?

It was published in June 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

MPT-30B— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language generation, Code generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

MPT-30B— where can I download it?

Its weights are published on Hugging Face, under the organisation mosaicml. We do not host model files — this site calculates what hardware is needed to run them.

MPT-30B— how much compute was used to train it?

Training consumed around 1.9 × 10²³ FLOP, on hardware recorded as NVIDIA H100 SXM5 80GB. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.

MPT-30B— can I run it if it does not fit in my GPU?

Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. The nearest miss we calculate falls short by 4.4 GB. Every figure here assumes the whole model is resident on the card.

MPT-30B— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 132. So a second card is rarely the answer here.

MPT-30B— why does the quantisation differ between cards?

Because capacity varies, so does how hard it has to be squeezed. The number of distinct levels in the table above: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.
