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 SambaLingo-Thai-Chat-70B

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 SambaLingo-Thai-Chat-70B

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

The hardware side

Minimum card

A100 PCIe 40 GB

Memory needed

34.9 GB

Fastest

48.4 tok/s

SambaLingo-Thai-Chat-70B reaches a parameter count of 70B. 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: 61.

At the low end it is handled by A100 PCIe 40 GB, with a memory capacity of 40 GB, running it at a compression of Q3_K_M and producing around 25.5 tokens per second.

The quickest result comes from B200, generating roughly 48.4 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

SambaLingo-Thai-Chat-70B was published by SambaNova Systems, Inc, 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 chat.

Rather than being trained from scratch, it is derived from Llama 2-70B. That is why it shares the base model's general shape and size.

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

How fast it runs, and why

The median result is around 17.1 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 50 of them.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

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.

What went into building it

Producing it required arithmetic totalling around 8.1 × 10²³ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Step by step

How to choose a GPU for SambaLingo-Thai-Chat-70B

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

Start from what it actually needs, which is the requirement of SambaLingo-Thai-Chat-70B, needing around 34.9 GB at a compression of Q3_K_M. That figure, not the headline performance of a card, is what decides whether it runs.
02

Set the context length you will work at

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 SambaLingo-Thai-Chat-70B.
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

Sort by speed

Ranking by tokens per second follows memory bandwidth rather than core counts, for SambaLingo-Thai-Chat-70B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 48.4 tok/s.
05

Check the fit verdict before buying

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of SambaLingo-Thai-Chat-70B. 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

Check the card from the other side

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 SambaLingo-Thai-Chat-70B.

Answers

SambaLingo-Thai-Chat-70B — common questions

SambaLingo-Thai-Chat-70B— 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.

SambaLingo-Thai-Chat-70B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 29–77 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

SambaLingo-Thai-Chat-70B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is A100 PCIe 40 GB, with a memory capacity of 40 GB. It runs the model at a compression of Q3_K_M using about 34.9 GB, and produces roughly 25.5 tokens per second. The number of cards able to run it in total: 61.

SambaLingo-Thai-Chat-70B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 48.4 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: 50.

SambaLingo-Thai-Chat-70B— how much VRAM does it need?

It needs about 34.9 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.

SambaLingo-Thai-Chat-70B— 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.

SambaLingo-Thai-Chat-70B— how many parameters does it have?

It has a parameter count of 70B. https://huggingface.co/sambanovasystems/SambaLingo-Thai-Chat-70B. 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.

SambaLingo-Thai-Chat-70B— who created it?

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

SambaLingo-Thai-Chat-70B— 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.

SambaLingo-Thai-Chat-70B— what is it used for?

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

SambaLingo-Thai-Chat-70B— where can I download it?

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

SambaLingo-Thai-Chat-70B— how much compute was used to train it?

Training consumed around 8.1 × 10²³ FLOP. 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.

SambaLingo-Thai-Chat-70B— 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 14.2 GB. Every figure here assumes the whole model is resident on the card.

SambaLingo-Thai-Chat-70B— would two GPUs run it faster?

Two cards buy memory rather than speed, which matters only if one card cannot hold it. The number that can: 61. So a second card is rarely the answer here.
