  • No, all the weights, all the “data” essentially has to be in RAM. If you “talk to” a LLM on your GPU, it is not making any calls to the internet, but making a pass through all the weights every time a word is generated.

    There are system to augment the prompt with external data (RAG is one word for this), but fundamentally the system is closed.


  • Oh I didn’t mean “should cost $4000” just “would cost $4000”

    Ah, yeah. Absolutely. The situation sucks though.

    I wish that the vram on video cards was modular, there’s so much ewaste generated by these bottlenecks.

    Not possible, the speeds are so high that GDDR physically has to be soldered. Future CPUs will be that way too, unfortunately. SO-DIMMs have already topped out at 5600, with tons of wasted power/voltage, and I believe desktop DIMMs are bumping against their limits too.

    But look into CAMM modules and LPCAMMS. My hope is that we will get modular LPDDR5X-8533 on AMD Strix Halo boards.


  • GDDR is actually super cheap! I think it would only be like another $75 on paper to double the 4090’s VRAM to 48GB (like they do for pro cards already).

    Nvidia just doesn’t do it for market segmentation. AMD doesn’t do it for… honestly I have no idea why? They basically have no pro market to lose, the only explanation I can come up with is that their CEOs are colluding because they are cousins. And Intel doesn’t do it because they didn’t make a (consumer) GPU that was eally worth it until the B580.


  • The issue with Macs is that Apple does price gouge for memory, your software stack is effectively limited to llama.cpp or MLX, and 70B class LLMs do start to chug, especially at high context.

    Diffusion is kinda a different duck. It’s more compute heavy, yes, but the “generally accessible” software stack is also much less optimized for Macs than it is for transformers LLMs.

    I view AMD Strix Halo as a solution to this, as its a big IGP with a wide memory bus like a Mac, but it can use the same CUDA software stacks that discrete GPUs use for that speed/feature advantage… albeit with some quirks. But I’m willing to put up with that if AMD doesn’t price gouge it.


  • second-hand TPU

    From where? I keep a look out for used Gaudi/TPU setups, but they’re like impossible to find, and usually in huge full-server configs. I can’t find Xeon Max GPUs or CPUs either.

    Also, Google’s software stack isn’t really accessible. TPUs are made for internal use at Google, not for resale.

    You can find used AMD MI100s or MI210s, sometimes, but the go-to used server card is still the venerable Tesla P40.


  • You can’t let it overflow if you’re using LLMs on windows. There’s a toggle for it in the Nvidia settings, and get llama.cpp to offload though its settings (or better yet, use exllama instead).

    But…. Yeah. Qwen 32B fits in 24GB perfectly, and it’s great, but 72B really feels like the intelligence tipping point where I can dump so many API models, and that won’t fit in 24GB.

    I’m self hosting LLMs for family use (cause screw OpenAI and corporate, closed AI), and I am dying for more VRAM and RAM now. Even if I had a 4090, it wouldn’t be nearly enough.

    My 3090 is sitting at 23.9GB/24GB because I keep Qwen 32B QwQ loaded and use it all the time. I even have my display hooked up to my IGP to save VRAM.

    Seriously looking at replacing my 7800X3D with Strix Halo when it comes out, maybe a 128GB board if they sell one. Or a 48GB Intel Arc if Intel is smart enough to sell that. And I would use every last megabyte, even if I had a 512GB board (which is the bare minimum to host Deepseek V3).


  • Truth is, with NuTrek, it doesn’t have a single progressive bone in its body, and the writers don’t have the skill to pull off any sort of commentary.

    It’s not that bad, though I don’t totally disagree.

    Also… I’d argue a problem is having their hands tied. Ironically, anything that would hit really hard couldn’t be aired in this day and age. The whole franchise would probably be mothballed if they pushed the envelope as hard as TOS.
