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 TeleChat2-35B

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 TeleChat2-35B

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

TeleChat2-35B reaches a parameter count of 35B. 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.

At the low end it is handled by RTX A4500, with a memory capacity of 20 GB, running it at a compression of Q3_K_M and producing around 20.9 tokens per second.

At the other end sits B200, generating roughly 96.8 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

TeleChat2-35B was published by China Telecom, in the country recorded as China, during October 2024. The category the publisher falls under is industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering, Quantitative reasoning, Chat, Text summarization, Code generation.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.

How fast it runs, and why

Half the cards that hold it manage more than 20.6 tokens per second. Producing text faster than most people read it: 103 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.

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.

Step by step

How to choose a GPU for TeleChat2-35B

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

01

Start from the memory column

Every card here has been checked against TeleChat2-35B, needing around 17.8 GB at a compression of Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
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 TeleChat2-35B.
03

Decide how much compression you will accept

The quantisation column varies by card, because a bigger card holds a more accurate copy, 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

Ranking by tokens per second follows memory bandwidth rather than core counts, for TeleChat2-35B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 96.8 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of TeleChat2-35B. 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

Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond TeleChat2-35B.

Answers

TeleChat2-35B — common questions

TeleChat2-35B— how much VRAM does it need?

It needs about 17.8 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.

TeleChat2-35B— 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 IQ4_XS, using about 19.8 GB and generating roughly 39.8 tokens per second. The fit is tight.

TeleChat2-35B— 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.

TeleChat2-35B— how many parameters does it have?

It has a parameter count of 35B. 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.

TeleChat2-35B— who created it?

It was published by China Telecom, based in China, an organisation categorised as industry.

TeleChat2-35B— when was it released?

It was published in October 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.

TeleChat2-35B— 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, Quantitative reasoning, Chat, Text summarization, Code generation. 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.

TeleChat2-35B— 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.

TeleChat2-35B— 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 7.5 GB. Every figure here assumes the whole model is resident on the card.

TeleChat2-35B— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 132. So a second card is rarely the answer here.

TeleChat2-35B— 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.

TeleChat2-35B— 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: 58–155 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

TeleChat2-35B— 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 17.8 GB, and produces roughly 20.9 tokens per second. The number of cards able to run it in total: 132.

TeleChat2-35B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 96.8 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: 103.
