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 Viking

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 Viking

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

16.8 GB

Fastest

103 tok/s

Viking reaches a parameter count of 33B. 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 Q3_K_M and producing around 22.2 tokens per second.

The fastest we calculate for it is B200, generating roughly 103 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

Viking was published by Silo AI,University of Turku, in the country recorded as Finland, during April 2024. It comes out of an organisation categorised as industry,Academia.

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

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all.

How fast it runs, and why

Across every card that can run it, the middle of the range sits at 20.3 tokens per second. Producing text faster than most people read it: 101 of them.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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 2.6 × 10²³ FLOP, on hardware recorded as AMD Radeon Instinct MI250X. That figure measures what producing the model cost, and has no bearing on how fast it answers.

The training set ran to roughly 2,000,000,000,000 tokens of text.

Step by step

How to choose a GPU for Viking

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

The table lists every card able to hold Viking, needing around 16.8 GB at a compression of Q3_K_M. That figure, not the headline performance of a card, is what decides whether it runs.
02

Match the context to your actual use

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect, because at long context a card that handles short questions easily can be dropped by Viking.
03

Choose how far you will compress it

Compression is what makes a model fit smaller cards, at some cost in accuracy, reaching a compression of Q3_K_M 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

Compare tokens per second, not specifications

Sort by speed to see how cards rank for Viking. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 103 tok/s.
05

Check the fit verdict before buying

Tight means it loads and works with no room to raise the context later, in the case of Viking. 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

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Viking.

Answers

Viking — common questions

Viking— how accurate are these speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked, which is why each is published as a range rather than a single number. One example: 62–164 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Viking— 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 Q3_K_M using about 16.8 GB, and produces roughly 22.2 tokens per second. The number of cards able to run it in total: 132.

Viking— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 103 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: 101.

Viking— how much VRAM does it need?

It needs about 16.8 GB at a compression of Q3_K_M, 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.

Viking— 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 20.7 GB and generating roughly 39.7 tokens per second. The fit is tight.

Viking— 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.

Viking— how many parameters does it have?

It has a parameter count of 33B. 33B. 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.

Viking— who created it?

It was published by Silo AI,University of Turku, based in Finland, an organisation categorised as industry,Academia.

Viking— when was it released?

It 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.

Viking— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Language generation, Translation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

Viking— where can I download it?

The weights are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

Viking— how much compute was used to train it?

Training consumed around 2.6 × 10²³ FLOP, on hardware recorded as AMD Radeon Instinct MI250X. 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.

Viking— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. The nearest miss we calculate falls short by 6.3 GB. Every figure here assumes the whole model is resident on the card.

Viking— would two GPUs run it faster?

A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 132. So a second card is rarely the answer here.

Viking— why does the quantisation differ between cards?

Each card is shown running the least-compressed copy it can hold. The number of distinct compression levels across the cards that fit it: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.
