>If the GPU has 16GB of VRAM, and the model is 70GB, can it still run well? Also, does it run considerably better than on a GPU with 12GB of VRAM?

No, it can't run at all.

>I run Ollama locally, mixtral works well (7B, 3.4GB) on a 1080ti, but the 24.6GB version is a bit slow (still usable, but has a noticeable start-up time).

That is not mixtral, that is mistral 7b. The 1080ti is slower than running inference on current generation threadripper cpus.

EDIT: This was ran on a 1080ti + 5900x. Initial generation takes around 10-30seconds (like it has to upload the model to GPU), but then it starts answering immediately, at around 3 words per second.


Did you check your GPU utilization?

Typically when it runs that way it runs on the CPU, not the GPU.

Are you sure you're actually offloading any work to the GPU?

At least with llama.cpp, there is no 'partially put a layer' into the GPU. Either you do, or you don't. You pick the number of layers. If the model is too big, the layers won't fit and it can't run at all.

The llama.cpp `main` executable will tell you in it's debug information when you use the -ngl flag; see https://github.com/ggerganov/llama.cpp/blob/master/examples/...

It's also possible you're running (eg. if you're using ollama) and quantized version of the model which reduces the memory requirements and quality of the model outputs.


I have to check, something does indeed seem weird, especially with the PC freezing like that. Maybe it runs on the CPU.

> quantized version Yes, it is 4bit quantized, but still has 24.6GB


this is some new flex to debate online: copying and pasting the other sides argument and waiting for your local LLM to explain why they are wrong.

how much is your hardware at today's value? what are the specs? that is impressive even though its 3 words per second. if you want to bump it up to 30, do you then 10x your current hardware cost?


That question was just an example (Lorem ipsum), it was easy to copy paste to demo the local LLM, I didn't intend to provide more context to the discussion.

I ordered a 2nd 3090, which has 24GB VRAM. Funny how it was $2.6k 3 years ago and now is $600.

You can probuild a decent AI local machine for around $1000.


https://howmuch.one/product/average-nvidia-geforce-rtx-3090-... you are right there is a huge drop in price


New it's hard to find, but the 2nd hand market is filled with them.


Where are you seeing 24GB 3090s for $600?


2nd hand market


Congratulations on using CPU inference.


I have those:

dolphin-mixtral:latest (24.6GB) mistral:latest (3.8GB)

The CPU is 5900x.
