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 CodeGeeX

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 CodeGeeX

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 it takes to run this model

Minimum card

Xeon Phi 5110P

Memory needed

7.1 GB

Fastest

261 tok/s

CodeGeeX is small enough at 13B parameters that hardware is rarely the obstacle — 509 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the Xeon Phi 5110P with 8 GB, running it at Q3_K_M and producing around 18.3 tokens per second.

Top of the range is the B200, at roughly 261 tokens per second thanks to 8,000 GB/s of bandwidth.

Where it came from

CodeGeeX was published by Z.ai (Zhipu AI),Tsinghua University, in China, in June 2022. The organisation is categorised as industry,Academia.

It works in Language, and is recorded as doing code generation.

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.

Understanding the speeds

The median result is around 21.2 tokens per second; 459 cards produce text faster than most people read it.

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

The training run consumed about 6.6 × 10²² FLOP, on Huawei Ascend 910. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Around 850,000,000,000 tokens went into training it.

Step by step

How to choose a GPU for CodeGeeX

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

The table lists every card that can hold CodeGeeX — around 7.1 GB at Q3_K_M. That figure, not the card's headline performance, 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 CodeGeeX stops fitting a card that seemed fine.
03

Set a quality floor

Compression is what makes CodeGeeX fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Compare tokens per second, not specifications

Ranking by tokens per second for CodeGeeX follows memory bandwidth, not core counts, which is why the B200 tops it at 261 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs CodeGeeX but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
06

See what else that card runs

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond CodeGeeX.

Answers

CodeGeeX — common questions

How much VRAM does CodeGeeX need?

About 7.1 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.

Can I run CodeGeeX on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q3_K_M, using about 7.1 GB and generating roughly 131 tokens per second — a tight fit.

Can I run CodeGeeX on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 10.1 GB and generating roughly 53.1 tokens per second — a tight fit.

Can I run CodeGeeX on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q6_K, using about 11.6 GB and generating roughly 53.5 tokens per second — a comfortable fit.

Can I run CodeGeeX on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 14.6 GB and generating roughly 43.7 tokens per second — a comfortable fit.

Is CodeGeeX open source?

Its weights are published, so CodeGeeX 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 CodeGeeX have?

CodeGeeX has 13B parameters. "We introduce CodeGeeX, a large-scale multilingual code generation model with 13 billion parameters". 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 CodeGeeX?

CodeGeeX was published by Z.ai (Zhipu AI),Tsinghua University, based in China, categorised as industry,Academia.

When was CodeGeeX released?

CodeGeeX was published in June 2022. 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 CodeGeeX used for?

CodeGeeX works in Language, and is recorded as handling code generation. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download CodeGeeX?

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

How much compute was used to train CodeGeeX?

Around 6.6 × 10²² FLOP, on Huawei Ascend 910. 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.

Can I run CodeGeeX 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 3.2 GB. Our figures for CodeGeeX assume it is fully resident.

Would two GPUs run CodeGeeX faster?

Two cards buy memory rather than speed. That matters for CodeGeeX only if one card cannot hold it — 509 can, so a second adds little.

Why does the quantisation differ between cards for CodeGeeX?

Because capacity varies, so does how hard CodeGeeX has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

How accurate are these CodeGeeX speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 156–417 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

What GPU do I need to run CodeGeeX?

The smallest card in our catalogue that holds CodeGeeX is the Xeon Phi 5110P, with 8 GB of memory. It runs the model at Q3_K_M using about 7.1 GB, and produces roughly 18.3 tokens per second. 509 cards in total can run it.

How fast is CodeGeeX on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 261 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 459 of the cards that can run CodeGeeX clear that.
