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 WizardLM-2 8x22B

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 WizardLM-2 8x22B

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

Memory needed

Fastest

29.1 tok/s

WizardLM-2 8x22B reaches a parameter count of 141B. That puts it above consumer hardware, into the range where a card is bought for this purpose rather than repurposed for it. The number of cards we track that can hold it: 37.

The least hardware that works is A100 SXM4 80 GB, with a memory capacity of 80 GB, running it at a compression of Q3_K_M and producing around 16.5 tokens per second.

The quickest result comes from H100 NVL 94 GB, generating roughly 29.1 tokens per second on the strength of a memory bandwidth of 3,940 GB/s.

Where it came from

WizardLM-2 8x22B was published by Microsoft, in the country recorded as United States of America, during April 2024. The publishing organisation is categorised as industry.

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

Rather than being trained from scratch, it is derived from Mixtral 8x22B. That is the usual way a specialised model is produced.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded. On Hugging Face it is published under the organisation alpindale.

Understanding the speeds

The median result is around 16.5 tokens per second. Exceeding reading speed outright: 35 of them.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

Memory here is estimated from size rather than computed from the architecture, which is not recorded for this model — the numbers are indicative rather than exact.

Step by step

How to choose a GPU for WizardLM-2 8x22B

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

01

Read the memory figure first

The table lists every card able to hold WizardLM-2 8x22B, needing around 69.6 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
02

Match the context to your actual use

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason a card that seemed fine stops fitting WizardLM-2 8x22B.
03

Set a quality floor

Each card runs the least-compressed copy it can hold, 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

Sort by speed

The speed ordering is effectively an ordering by memory bandwidth, for WizardLM-2 8x22B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is H100 NVL 94 GB, at 29.1 tok/s.
05

Read the fit column last

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of WizardLM-2 8x22B. 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 WizardLM-2 8x22B.

Answers

WizardLM-2 8x22B — common questions

WizardLM-2 8x22B— 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.

WizardLM-2 8x22B— what is it used for?

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

WizardLM-2 8x22B— where can I download it?

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

WizardLM-2 8x22B— 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 21.2 GB. Every figure here assumes the whole model is resident on the card.

WizardLM-2 8x22B— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 37. So a second card is rarely the answer here.

WizardLM-2 8x22B— 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: 6. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

WizardLM-2 8x22B— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 17–47 tok/s on H100 NVL 94 GB. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

WizardLM-2 8x22B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is A100 SXM4 80 GB, with a memory capacity of 80 GB. It runs the model at a compression of Q3_K_M using about 69.6 GB, and produces roughly 16.5 tokens per second. The number of cards able to run it in total: 37.

WizardLM-2 8x22B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is H100 NVL 94 GB, at about 29.1 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: 35.

WizardLM-2 8x22B— how much VRAM does it need?

It needs about 69.6 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.

WizardLM-2 8x22B— 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.

WizardLM-2 8x22B— how many parameters does it have?

It has a parameter count of 141B. Parameters: 141B. 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.

WizardLM-2 8x22B— who created it?

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