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

What the numbers mean

What it takes to run this model

Minimum card

FirePro S9170

Memory needed

27.2 GB

Fastest

310 tok/s

Phi-3.5-MoE sits at 60.8B parameters, which puts it above consumer hardware and into the range where a card is bought for this purpose rather than repurposed for it. 92 of the cards we track can hold it.

The smallest card that holds it is the FirePro S9170 with 32 GB, running it at Q3_K_M and producing around 26.1 tokens per second.

The quickest result comes from a B200 at around 310 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

About this model

Phi-3.5-MoE was published by Microsoft, in United States of America, in April 2024. The organisation is categorised as industry.

It works in Language, and is recorded as doing language modeling/generation, Translation, Question answering, Code generation, Quantitative reasoning.

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

How fast it runs, and why

Across every card that can run it, the middle of the range is about 79.0 tokens per second, and 92 of them clear the ten tokens per second that roughly matches reading speed.

This is a mixture-of-experts model, which routes each token through only part of itself. It therefore generates far faster than its total size suggests — while still needing every parameter resident in memory, so it is quick without being cheap to hold.

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

Producing it required around 3 × 10²³ FLOP of arithmetic, on NVIDIA H100 SXM5 80GB, which is a statement about the training budget rather than about inference.

Step by step

How to choose a GPU for Phi-3.5-MoE

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

  1. 01

    Start from the memory column

    Look at what Phi-3.5-MoE actually needs — around 27.2 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Decide how long your conversations run

    The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Phi-3.5-MoE can slip off a card that handles short questions easily.

  3. 03

    Set a quality floor

    Compression is what makes Phi-3.5-MoE fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.

  4. 04

    Compare tokens per second, not specifications

    Sort by speed to see how cards rank for Phi-3.5-MoE. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 310 tok/s.

  5. 05

    Look at the headroom, not just the fit

    Tight means Phi-3.5-MoE loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.

  6. 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 Phi-3.5-MoE is settled.

Answers

Phi-3.5-MoE — common questions

01

What is Phi-3.5-MoE used for?

Phi-3.5-MoE works in Language, and is recorded as handling language modeling/generation, Translation, Question answering, Code generation, Quantitative reasoning. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

02

Where can I download Phi-3.5-MoE?

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

03

How much compute was used to train Phi-3.5-MoE?

Around 3 × 10²³ FLOP, on 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.

04

Can I run Phi-3.5-MoE if it does not fit in my GPU?

It can be split between the card and system memory, but Phi-3.5-MoE generates painfully slowly that way — the nearest miss we calculate is short by 9.1 GB. Nothing on this page assumes offloading.

05

Would two GPUs run Phi-3.5-MoE faster?

Two cards buy memory rather than speed. That matters for Phi-3.5-MoE only if one card cannot hold it — 92 can, so a second adds little.

06

Why does the quantisation differ between cards for Phi-3.5-MoE?

A larger card holds a more accurate copy. Across the cards that run Phi-3.5-MoE, 5 compression levels are used; the floor control above pins it to one.

07

How accurate are these Phi-3.5-MoE speed estimates?

These are estimates with real error bars. The fastest result here, 186–495 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

08

What GPU do I need to run Phi-3.5-MoE?

The smallest card in our catalogue that holds Phi-3.5-MoE is the FirePro S9170, with 32 GB of memory. It runs the model at Q3_K_M using about 27.2 GB, and produces roughly 26.1 tokens per second. 92 cards in total can run it.

09

How fast is Phi-3.5-MoE on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 310 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 92 of the cards that can run Phi-3.5-MoE clear that.

10

How much VRAM does Phi-3.5-MoE need?

About 27.2 GB at Q3_K_M 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.

11

Is Phi-3.5-MoE open source?

Its weights are published, so Phi-3.5-MoE 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.

12

How many parameters does Phi-3.5-MoE have?

Phi-3.5-MoE has 60.8B parameters. "Phi-3.5-MoE has 16x3.8B parameters with 6.6B active parameters when using 2 experts. The model is a mixture-of-expert decoder-only Transformer model using the tokenizer with vocabulary size of 32,064.". 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.

13

Who created Phi-3.5-MoE?

Phi-3.5-MoE was published by Microsoft, based in United States of America, categorised as industry.

14

When was Phi-3.5-MoE released?

Phi-3.5-MoE was published in April 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
