Fastest

13,235 tok/s

Denoising Diffusion Probabilistic Models (LSUN Bedroom) is small enough at 256M parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The entry point is the Tesla C1080: 4 GB of memory, Q8_0 compression, roughly 144 tokens per second.

A B200 is the fastest we calculate for it: about 13,235 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

Denoising Diffusion Probabilistic Models (LSUN Bedroom) was published by University of California (UC) Berkeley, in United States of America, in June 2021. The organisation is categorised as academia.

It works in Vision, and is recorded as doing image generation.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all.

How fast it runs, and why

The median result is around 371.7 tokens per second; 818 cards produce text faster than most people read it.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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.

How it was trained

Producing it required around 7.8 × 10¹⁹ FLOP of arithmetic, on Google TPU v3, which is a statement about the training budget rather than about inference.

It was trained on about 596,320,321,536 tokens of text.

Its inclusion criterion is highly cited,SOTA improvement.

Step by step

How to choose a GPU for Denoising Diffusion Probabilistic Models (LSUN Bedroom)

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

    Every card here has been checked against Denoising Diffusion Probabilistic Models (LSUN Bedroom) — around 1.0 GB at Q8_0. Capacity is the gate — a card either holds it or it does not.

  2. 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 Denoising Diffusion Probabilistic Models (LSUN Bedroom) stops fitting a card that seemed fine.

  3. 03

    Decide how much compression you will accept

    The quantisation column varies by card, because a bigger card holds a more accurate copy of Denoising Diffusion Probabilistic Models (LSUN Bedroom) — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Sort by speed

    Sort by speed to see how cards rank for Denoising Diffusion Probabilistic Models (LSUN Bedroom). It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 13,235 tok/s.

  5. 05

    Look at the headroom, not just the fit

    Tight means Denoising Diffusion Probabilistic Models (LSUN Bedroom) loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.

  6. 06

    Open the card you have settled on

    Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Denoising Diffusion Probabilistic Models (LSUN Bedroom).

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 1.0 GB and generating roughly 2,217 tokens per second — a comfortable fit.

07

Is Denoising Diffusion Probabilistic Models (LSUN Bedroom) open source?

Its weights are published, so Denoising Diffusion Probabilistic Models (LSUN Bedroom) 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.

08

How many parameters does Denoising Diffusion Probabilistic Models (LSUN Bedroom) have?

Denoising Diffusion Probabilistic Models (LSUN Bedroom) has 256M parameters. Appendix B: " Our CIFAR10 model has 35.7 million parameters, and our LSUN and CelebA-HQ models have 114 million parameters. We also trained a larger variant of the LSUN Bedroom model with approximately 256 million parameters by increasing filter count.". 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.

09

Who created Denoising Diffusion Probabilistic Models (LSUN Bedroom)?

Denoising Diffusion Probabilistic Models (LSUN Bedroom) was published by University of California (UC) Berkeley, based in United States of America, categorised as academia.

10

When was Denoising Diffusion Probabilistic Models (LSUN Bedroom) released?

Denoising Diffusion Probabilistic Models (LSUN Bedroom) was published in June 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.
