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 CodeT5+

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 CodeT5+

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

Hardware requirements in practice

Minimum card

P102-101

Memory needed

8.5 GB

Fastest

212 tok/s

CodeT5+ reaches a parameter count of 16B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 306.

The entry point is P102-101, with a memory capacity of 10 GB, running it at a compression of Q3_K_M and producing around 19.5 tokens per second.

The quickest result comes from B200, generating roughly 212 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

CodeT5+ was published by Salesforce, in the country recorded as United States of America, during May 2023. It comes out of an organisation categorised as industry.

It works in the domain of Language, and is recorded as performing the task of code generation, Code autocompletion.

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 Salesforce.

Reading the throughput figures

The median result is around 19.8 tokens per second. Exceeding reading speed outright: 259 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

The training set ran to roughly 51,500,000,000 tokens of text.

Its inclusion criterion: sOTA improvement.

Step by step

How to choose a GPU for CodeT5+

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

Every card here has been checked against CodeT5+, needing around 8.5 GB at a compression of Q3_K_M. Capacity is the gate — a card either holds it or it does not.
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, because at long context a card that handles short questions easily can be dropped by CodeT5+.
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

Rank by throughput rather than spec sheet

Sort by speed to see how cards rank for CodeT5+. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 212 tok/s.
05

Read the fit column last

A tight fit runs, but leaves nothing spare for a longer conversation, in the case of CodeT5+. 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

Following a card through to its own page shows every other model it can hold, which is the question that follows once you have settled on CodeT5+.

Answers

CodeT5+ — common questions

CodeT5+— 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 Q8_0, using about 17.8 GB and generating roughly 35.5 tokens per second. The fit is comfortable.

CodeT5+— 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.

CodeT5+— how many parameters does it have?

It has a parameter count of 16B. "We implemented a family of CodeT5+ models, with model sizes ranging from 220M to 16B". 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.

CodeT5+— who created it?

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

CodeT5+— when was it released?

It was published in May 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

CodeT5+— what is it used for?

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

CodeT5+— where can I download it?

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

CodeT5+— can I run it if it does not fit in my GPU?

Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. The nearest miss we calculate falls short by 3.2 GB. Every figure here assumes the whole model is resident on the card.

CodeT5+— 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: 306. So a second card is rarely the answer here.

CodeT5+— why does the quantisation differ between cards?

Because capacity varies, so does how hard it has to be squeezed. The number of distinct levels in the table above: 5. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

CodeT5+— 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: 127–339 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

CodeT5+— what GPU do I need to run it?

The smallest card in our catalogue that holds it is P102-101, with a memory capacity of 10 GB. It runs the model at a compression of Q3_K_M using about 8.5 GB, and produces roughly 19.5 tokens per second. The number of cards able to run it in total: 306.

CodeT5+— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 212 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: 259.

CodeT5+— how much VRAM does it need?

It needs about 8.5 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.

CodeT5+— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q4_K_M, using about 10.4 GB and generating roughly 55.8 tokens per second. The fit is tight.

CodeT5+— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q6_K, using about 14.1 GB and generating roughly 43.5 tokens per second. The fit is tight.
