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 for NexusRaven-V2

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 NexusRaven-V2

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

Xeon Phi 5110P

Memory needed

7.1 GB

Fastest

261 tok/s

NexusRaven-V2 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 entry point is the Xeon Phi 5110P: 8 GB of memory, Q3_K_M compression, roughly 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.

Background

NexusRaven-V2 was published by Nexusflow, in United States of America, in December 2023. industry is the category the publisher falls under.

It works in Language, and is recorded as doing language modeling/generation, Code generation.

It builds on Code Llama-13B, which is why it shares that model's general shape and size.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.

Reading the throughput figures

Across every card that can run it, the middle of the range is about 21.2 tokens per second, and 459 of them clear the ten tokens per second that roughly matches reading speed.

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.

Step by step

How to choose a GPU for NexusRaven-V2

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

Look at what NexusRaven-V2 actually needs — around 7.1 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
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 NexusRaven-V2 stops fitting a card that seemed fine.
03

Decide how much compression you will accept

Compression is what makes NexusRaven-V2 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 NexusRaven-V2 follows memory bandwidth, not core counts, which is why the B200 tops it at 261 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage NexusRaven-V2 from those with room to spare. Buy for the second if the context might grow.
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 NexusRaven-V2 is settled.

Answers

NexusRaven-V2 — common questions

Who created NexusRaven-V2?

NexusRaven-V2 was published by Nexusflow, based in United States of America, categorised as industry.

When was NexusRaven-V2 released?

NexusRaven-V2 was published in December 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.

What is NexusRaven-V2 used for?

NexusRaven-V2 works in Language, and is recorded as handling language modeling/generation, 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.

Where can I download NexusRaven-V2?

The weights for NexusRaven-V2 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

Can I run NexusRaven-V2 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 NexusRaven-V2 is rarely worth using — the nearest miss we calculate is short by 3.2 GB. Every figure here assumes the whole model is on the card.

Would two GPUs run NexusRaven-V2 faster?

Capacity adds across cards; throughput does not. Since 509 of the cards we track already hold NexusRaven-V2 on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for NexusRaven-V2?

Each card is shown running the least-compressed copy it can hold, and NexusRaven-V2 appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these NexusRaven-V2 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 NexusRaven-V2?

The smallest card in our catalogue that holds NexusRaven-V2 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 NexusRaven-V2 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 NexusRaven-V2 clear that.

How much VRAM does NexusRaven-V2 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 NexusRaven-V2 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 NexusRaven-V2 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 NexusRaven-V2 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 NexusRaven-V2 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 NexusRaven-V2 open source?

Its weights are published, so NexusRaven-V2 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 NexusRaven-V2 have?

NexusRaven-V2 has 13B parameters. 13B. 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.
