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.

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

0.9 GB

Fastest

15,401 tok/s

CodeT5-base reaches a parameter count of 220M. 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: 818.

The entry point is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 168 tokens per second.

At the other end sits B200, generating roughly 15,401 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

What this model is

CodeT5-base was published by Salesforce,Nanyang Technological University, in the country recorded as United States of America, during November 2021. The category the publisher falls under is industry,Academia.

It works in the domain of Language, and is recorded as performing the task of 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.

What decides the speed

The median result is around 432.5 tokens per second. Exceeding reading speed outright: 818 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.

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Training and provenance

The training run consumed about 1.6 × 10²¹ FLOP, on hardware recorded as NVIDIA A100. That figure measures what producing the model cost, and has no bearing on how fast it answers.

The reason it appears in this catalogue at all: sOTA improvement.

Step by step

How to choose a GPU for CodeT5-base

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

  1. 01

    Read the memory figure first

    Start from what it actually needs, which is the requirement of CodeT5-base, needing around 0.9 GB at a compression of Q8_0. Capacity is the gate — a card either holds it or it does not.

  2. 02

    Match the context to your actual use

    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 CodeT5-base.

  3. 03

    Decide how much compression you will accept

    Each card runs the least-compressed copy it can hold, reaching a compression of Q8_0 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.

  4. 04

    Rank by throughput rather than spec sheet

    The speed ordering is effectively an ordering by memory bandwidth, for CodeT5-base. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 15,401 tok/s.

  5. 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 CodeT5-base. 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.

  6. 06

    See what else that card runs

    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-base.

Answers

CodeT5-base — common questions

01

CodeT5-base— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q8_0, using about 0.9 GB and generating roughly 2,868 tokens per second. The fit is comfortable.

02

CodeT5-base— 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 Q8_0, using about 0.9 GB and generating roughly 1,756 tokens per second. The fit is comfortable.

03

CodeT5-base— 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 Q8_0, using about 0.9 GB and generating roughly 2,175 tokens per second. The fit is comfortable.

04

CodeT5-base— 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 0.9 GB and generating roughly 2,580 tokens per second. The fit is comfortable.

05

CodeT5-base— 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.

06

CodeT5-base— how many parameters does it have?

It has a parameter count of 220M. "We build CodeT5 based on Huggingface’s T5 (Raffel et al., 2020) PyTorch implementation and employ two sizes of CodeT5-small (60M) and CodeT5-base (220M)". 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.

07

CodeT5-base— who created it?

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

08

CodeT5-base— when was it released?

It was published in November 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

09

CodeT5-base— what is it used for?

It works in the domain of Language, and is recorded as handling the task of 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.

10

CodeT5-base— 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.

11

CodeT5-base— how much compute was used to train it?

Training consumed around 1.6 × 10²¹ FLOP, on hardware recorded as NVIDIA A100. 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.

12

CodeT5-base— 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. Every figure here assumes the whole model is resident on the card.

13

CodeT5-base— would two GPUs run it faster?

A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 818. So a second card is rarely the answer here.

14

CodeT5-base— 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: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

15

CodeT5-base— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 9,241–24,642 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

16

CodeT5-base— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q8_0 using about 0.9 GB, and produces roughly 168 tokens per second. The number of cards able to run it in total: 818.

17

CodeT5-base— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 15,401 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: 818.

18

CodeT5-base— how much VRAM does it need?

It needs about 0.9 GB at a compression of Q8_0, 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.
