Not sure if this is the right place, if not please let me know.
GPU prices in the US have been a horrific bloodbath with the scalpers recently. So for this discussion, let’s keep it to MSRP and the lucky people who actually managed to afford those insane MSRPs + managed to actually find the GPU they wanted.
Which GPU are you using to run what LLMs? How is the performance of the LLMs you have selected? On an average, what size of LLMs are you able to run smoothly on your GPU (7B, 14B, 20-24B etc).
What GPU do you recommend for decent amount of VRAM vs price (MSRP)? If you’re using the TOTL RX 7900XTX/4090/5090 with 24+ GB of RAM, comment below with some performance estimations too.
My use-case: code assistants for Terraform + general shell and YAML, plain chat, some image generation. And to be able to still pay rent after spending all my savings on a GPU with a pathetic amount of VRAM (LOOKING AT BOTH OF YOU, BUT ESPECIALLY YOU NVIDIA YOU JERK). I would prefer to have GPUs for under $600 if possible, but I want to also run models like Mistral small so I suppose I don’t have a choice but spend a huge sum of money.
Thanks
You can probably tell that I’m not very happy with the current PC consumer market but I decided to post in case we find any gems in the wild.
Thank you. Are 14B models the biggest you can run comfortably?
The coder model has only that one. The ones bigger than that are like 20GB+, and my GPU has 16GB. I’ve only tried two models, but it looked like the size balloons after that, so that may be the biggest models that I can run.
Do you have any recommendations for running the Mistral small model? I’m very interested in it alongside CodeLlama, OogaBooga and others
I haven’t tried those, so not really, but with open web UI, you can download and run anything, just make sure it fits in your vram so it doesn’t run on the CPU. The deep seek one is decent. I find that i like chatgpt 4-o better, but it’s still good.
In general how much VRAM do I need for 14B and 24B models?
It really depends on how you quantize the model and the K/V cache as well. This is a useful calculator. https://smcleod.net/vram-estimator/ I can comfortably fit most 32b models quantized to 4-bit (usually KVM or IQ4XS) on my 3090’s 24 GB of VRAM with a reasonable context size. If you’re going to be needing a much larger context window to input large documents etc then you’d need to go smaller with the model size (14b, 27b etc) or get a multi GPU set up or something with unified memory and a lot of ram (like the Mac Minis others are mentioning).
Oh and I typically get 16-20 tok/s running a 32b model on Ollama using Open WebUI. Also I have experienced issues with 4-bit quantization for the K/V cache on some models myself so just FYI
