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

Why memory is the number that matters here

Memory

16 GB

Bandwidth

436 GB/s

Largest model

Nemotron 3-Nano-30B-A3B

16 GB of HBM2 puts the Radeon Instinct MI25 comfortably into small and mid-sized models, with roughly 14.4 GB usable once the driver overhead is taken out. The largest models are out of reach without splitting them.

The memory bus moves 436 GB/s across a 2,048-bit bus. That is the number that governs generation speed — arithmetic per byte read is small enough that the bus, not the cores, is what everything waits on.

That comes from a 852 MHz 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 practical ceiling is Nemotron 3-Nano-30B-A3B at 31.6B, held at Q3_K_M and running at roughly 68.4 tokens per second.

The chip and how it was built

The Radeon Instinct MI25 is built on the Vega 10 graphics processor, using AMD's GCN 5.0 architecture, as part of the Radeon Instinct(MIx) generation.

The chip is manufactured by GlobalFoundries, on a 14 nm process, with a die measuring 495 mm², holding 12.5 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 June 2017, roughly 9 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

FP16

24.6 TFLOPS

FP64

768 GFLOPS

On paper the Radeon Instinct MI25 reaches 24.6 TFLOPS at half precision and 12.3 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 768 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.

Clocks run from 1.4 GHz at base to 1.5 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 Radeon Instinct MI25 has 16 KB of L1 cache, backed by 4 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 4,096 shading units, 256 texture mapping units, and 64 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

300 W

The Radeon Instinct MI25 is rated at 300 W, with a 700 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 2x 8-pin. 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 3.0 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 Radeon Instinct MI25

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.

  1. 01

    Search for the model you want

    Every one of the 432 models this Radeon Instinct MI25 runs is in the table above. Search narrows it by name or by size.

  2. 02

    Decide how long your conversations run

    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 16 GB.

  3. 03

    Choose how far you will compress

    Each model is shown at the best compression this card can hold. A minimum quality hides the ones that only fit by being squeezed further than you would accept.

  4. 04

    Look at the range, not just the number

    The figures are calculated, not measured. 144 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.

  5. 05

    Read the fit verdict last

    The fit column separates models that just fit from those with room to spare — worth checking against the card's 16 GB before settling on one.

  6. 06

    Cross-check against other hardware

    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 Radeon Instinct MI25 is the right buy for it or merely a card that fits.

Answers

Radeon Instinct MI25 — common questions

01

What bus interface does the Radeon Instinct MI25 use?

It uses PCIe 3.0 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.

02

Is the Radeon Instinct MI25 good for running local AI models?

Its memory covers small and mid-sized models, though the largest are out of reach and its bandwidth gives usable, if unspectacular, generation speeds. In total it runs 432 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

03

Can a Radeon Instinct MI25 run a model that does not fit in its memory?

It can be split, with the overflow held in system memory — but that part drags the whole thing down, and none of the 16 GB figures on this page assume it.

04

Would two Radeon Instinct MI25 cards be twice as fast?

No. A second Radeon Instinct MI25 doubles the memory to 32 GB, which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.

05

What AI models can a Radeon Instinct MI25 run?

432 of the 679 open-weight language models we track fit on a Radeon Instinct MI25 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.

06

What is the largest AI model a Radeon Instinct MI25 can run?

The largest model in our catalogue that fits on a Radeon Instinct MI25 is Nemotron 3-Nano-30B-A3B at 31.6B parameters, compressed to Q3_K_M. It generates roughly 68.4 tokens per second and needs about 14.4 GB of the card's memory.

07

How many tokens per second does a Radeon Instinct MI25 produce?

It depends on the model. On a Radeon Instinct MI25 the fastest model we track is Gemma 3 QAT 1B at about 144 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.

08

Can a Radeon Instinct MI25 run a 7B model?

Yes. For example a Radeon Instinct MI25 runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 21.5 tokens per second.

09

Can a Radeon Instinct MI25 run a 13B model?

Yes. For example a Radeon Instinct MI25 runs DeepSeekMoE-16B at Q6_K, using about 13.7 GB of memory and generating around 72.7 tokens per second.

10

Can a Radeon Instinct MI25 run a 30B model?

Yes. For example a Radeon Instinct MI25 runs ERNIE-4.5-VL-28B-A3B at Q3_K_M, using about 12.9 GB of memory and generating around 77.2 tokens per second.

11

How much memory does a Radeon Instinct MI25 have?

A Radeon Instinct MI25 has 16 GB of HBM2 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 14.4 GB available for a model and its conversation.

12

What is the memory bandwidth of a Radeon Instinct MI25?

The Radeon Instinct MI25 has 436 GB/s of memory bandwidth, across a 2,048-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.

13

What type of memory does a Radeon Instinct MI25 use?

It uses HBM2 clocked at 852 MHz. 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.

14

Who makes the Radeon Instinct MI25?

The Radeon Instinct MI25 is a AMD product, with the chip manufactured by GlobalFoundries, on a 14 nm process.

15

When was the Radeon Instinct MI25 released?

The Radeon Instinct MI25 was released in June 2017.

16

How much power does a Radeon Instinct MI25 use?

The Radeon Instinct MI25 has a rated board power of 300 W, and a 700 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.

17

How much cache does a Radeon Instinct MI25 have?

The Radeon Instinct MI25 has 16 KB of L1 cache, and 4 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.

18

What are the TFLOPS of a Radeon Instinct MI25?

The Radeon Instinct MI25 is rated at 24.6 TFLOPS at half precision and 12.3 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.

19

Does the Radeon Instinct MI25 support CUDA?

No. CUDA is NVIDIA-only, and the Radeon Instinct MI25 is a AMD card. It runs language models through ROCm, Vulkan or Metal depending on the software, which are less mature than the CUDA path — our estimates apply a penalty for that.
