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.

Memory needed

With 46.7B parameters, GRITLM 8x7B lands in the range a serious desktop card can handle once the weights are compressed. 93 of the cards we track can run it.
The least hardware that works is a Radeon PRO V710. Its 28 GB is enough at Q3_K_M compression, giving roughly 9.6 tokens per second.
At the other end, a B200 generates roughly 72.6 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.
About this model
GRITLM 8x7B was published by Contextual AI,The University of Hong Kong,Microsoft, in United States of America, in April 2024. The organisation is categorised as industry,Academia,Industry.
It works in Language, and is recorded as doing language modeling/generation, Question answering, Quantitative reasoning.
It is derived from Mixtral 8x7B rather than trained from scratch, which is the usual way a specialised model is produced.
The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold.
How fast it runs, and why
Half the cards that hold it manage more than 18.3 tokens per second, and 74 exceed reading speed outright.
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 GRITLM 8x7B
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
Look at what GRITLM 8x7B actually needs — around 23.5 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
-
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 GRITLM 8x7B can slip off a card that handles short questions easily.
-
03
Decide how much compression you will accept
The quantisation column varies by card, because a bigger card holds a more accurate copy of GRITLM 8x7B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.
-
04
Sort by speed
Ranking by tokens per second for GRITLM 8x7B follows memory bandwidth, not core counts, which is why the B200 tops it at 72.6 tok/s.
-
05
Read the fit column last
Tight means GRITLM 8x7B 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.
-
06
Open the card you have settled on
Following a card through to its own page shows every other model it can hold, which is the question that follows once GRITLM 8x7B is settled.
Answers
GRITLM 8x7B — common questions
When was GRITLM 8x7B released?
GRITLM 8x7B 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.
What is GRITLM 8x7B used for?
GRITLM 8x7B works in Language, and is recorded as handling language modeling/generation, Question answering, Quantitative reasoning. These are the areas it was designed around; they describe intent rather than a hard boundary.
Where can I download GRITLM 8x7B?
The weights for GRITLM 8x7B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.
Can I run GRITLM 8x7B if it does not fit in my GPU?
Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down — the nearest miss we calculate is short by 7.4 GB. Our figures for GRITLM 8x7B assume it is fully resident.
Would two GPUs run GRITLM 8x7B faster?
Two cards buy memory rather than speed. That matters for GRITLM 8x7B only if one card cannot hold it — 93 can, so a second adds little.
Why does the quantisation differ between cards for GRITLM 8x7B?
A larger card holds a more accurate copy. Across the cards that run GRITLM 8x7B, 5 compression levels are used; the floor control above pins it to one.
How accurate are these GRITLM 8x7B speed estimates?
Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 44–116 tok/s on the B200 rather than a single number.
What GPU do I need to run GRITLM 8x7B?
The smallest card in our catalogue that holds GRITLM 8x7B is the Radeon PRO V710, with 28 GB of memory. It runs the model at Q3_K_M using about 23.5 GB, and produces roughly 9.6 tokens per second. 93 cards in total can run it.
How fast is GRITLM 8x7B on a GPU?
It depends on the card. The quickest we calculate is a B200 at about 72.6 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 74 of the cards that can run GRITLM 8x7B clear that.
How much VRAM does GRITLM 8x7B need?
About 23.5 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.
Is GRITLM 8x7B open source?
Its weights are published, so GRITLM 8x7B 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.
How many parameters does GRITLM 8x7B have?
GRITLM 8x7B has 46.7B parameters. 46.7B. 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.
Who created GRITLM 8x7B?
GRITLM 8x7B was published by Contextual AI,The University of Hong Kong,Microsoft, based in United States of America, categorised as industry,Academia,Industry.
