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 SimCLRv2

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 SimCLRv2

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

The hardware side

Minimum card

Tesla C1080

Memory needed

1.6 GB

Fastest

4,262 tok/s

SimCLRv2 reaches a parameter count of 795M. 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.

At the low end it is handled by Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 46.4 tokens per second.

The quickest result comes from B200, generating roughly 4,262 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

What this model is

SimCLRv2 was published by Google Brain, in the country recorded as United States of America, during October 2020. It comes out of an organisation categorised as industry.

It works in the domain of Vision, and is recorded as performing the task of image classification.

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.

What decides the speed

The median result is around 119.7 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 809 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 set ran to roughly 20,937,965,568 tokens of text.

Step by step

How to choose a GPU for SimCLRv2

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

01

Read the memory figure first

The table lists every card able to hold SimCLRv2, needing around 1.6 GB at a compression of Q8_0. Capacity is the gate — a card either holds it or it does not.
02

Set the context length you will work at

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for SimCLRv2.
03

Choose how far you will compress it

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.
04

Rank by throughput rather than spec sheet

The speed ordering is effectively an ordering by memory bandwidth, for SimCLRv2. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 4,262 tok/s.
05

Look at the headroom, not just the fit

Tight means it loads and works with no room to raise the context later, in the case of SimCLRv2. 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

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for SimCLRv2.

Answers

SimCLRv2 — common questions

SimCLRv2— 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.

SimCLRv2— how many parameters does it have?

It has a parameter count of 795M. From author communication We trained different model sizes (from 24M to 795M), and they're summarized in Table 1 of the paper (https://arxiv.org/pdf/2006.10029.pdf). 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.

SimCLRv2— who created it?

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

SimCLRv2— when was it released?

It was published in October 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

SimCLRv2— what is it used for?

It works in the domain of Vision, and is recorded as handling the task of image classification. These are the areas it was designed around; they describe intent rather than a hard boundary.

SimCLRv2— 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.

SimCLRv2— can I run it if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part held in system memory drags the whole thing down. Every figure here assumes the whole model is resident on the card.

SimCLRv2— 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.

SimCLRv2— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

SimCLRv2— 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: 2,557–6,819 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

SimCLRv2— 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 1.6 GB, and produces roughly 46.4 tokens per second. The number of cards able to run it in total: 818.

SimCLRv2— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 4,262 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: 809.

SimCLRv2— how much VRAM does it need?

It needs about 1.6 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.

SimCLRv2— 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 1.6 GB and generating roughly 794 tokens per second. The fit is comfortable.

SimCLRv2— 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 1.6 GB and generating roughly 486 tokens per second. The fit is comfortable.

SimCLRv2— 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 1.6 GB and generating roughly 602 tokens per second. The fit is comfortable.

SimCLRv2— 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 1.6 GB and generating roughly 714 tokens per second. The fit is comfortable.
