Earlier quoted context omitted.

Yeah especially since what is happening in the memory market

Feast and famine. In three years we will be swimming in more ram than we know what to do with.

Kind of feel that's already the case today... 4GB I find is still plenty for even business workloads.

I feel like there's no point to get a graphics card nowadays. Clearly, graphics cards are optimized for graphics; they just happened to be good for AI but based on the increased significance of AI, I'd be surprised if we don't get more specialized chips and specialized machines just for LLMs. One for LLMs, a different one for stable diffusion.

With graphics processing, you need a lot of bandwidth to get stuff in and out of the graphics card for rendering on a high-resolution screen, lots of pixels, lots of refreshes, lots of bandwidth... With LLMs, a relatively small amount of text goes in and a relatively small amount of text comes out over a reasonably long amount of time. The amount of internal processing is huge relative to the size of input and output. I think NVIDIA and a few other companies already started going down that route.

But probably graphics cards will still be useful for stable diffusion; especially AI-generated videos as the inputs and output bandwidth is much higher.

Seems like wishful thinking.

> How many TOPS do you need to run state-of-the-art models with hundreds of millions of parameters? No one knows exactly.

Why not extrapolate from open-source AIs which are available? The most powerful open-source AI (which I know of) is Kimi K2 and >600gb. Running this at acceptable speed requires 600+gb GPU/NPU memory. Even $2000-3000 AI-focused PCs like the DGX spark or Strix Halo typically top out at 128gb. Frontier models will only run on something that costs many times a typical consumer PC, and only going to get worse with RAM pricing.

In 2010 the typical consumer PC had 2-4gb of RAM. Now the typical PC has 12-16gb. This suggests RAM size doubling perhaps every 5 years at best. If that's the case, we're 25-30 years away from the typical PC having enough RAM to run Kimi K2.

But the typical user will never need that much RAM for basic web browsing, etc. The typical computer RAM size is not going to keep growing indefinitely.

What about cheaper models? It may be possible to run a "good enough" model on consumer hardware eventually. But I suspect that for at least 10-15 years, typical consumers (HN readers may not be typical!) will prefer capability, cheapness, and especially reliability (not making mistakes) over being able to run the model locally. (Yes AI datacenters are being subsidized by investors; but they will remain cheaper, even if that ends, due to economies of scale.)

The economics dictate that AI PCs are going to remain a niche product, similar to gaming PCs. Useful AI capability is just too expensive to add to every PC by default. It's like saying flying is so important, everyone should own an airplane. For at least a decade, likely two, it's just not cost-effective.

I was in the market for a laptop this month. Many new laptops now advertise AI features like this "HP OmniBook 5 Next Gen AI PC" which advertises: "SNAPDRAGON X PLUS PROCESSOR - Achieve more everyday with responsive performance for seamless multitasking with AI tools that enhance productivity and connectivity while providing long battery life" I don't want this garbage on my laptop, especially when its running of its…

Laptop manufacturers are too desperate to cash on the AI craze. There's nothing special about an 'AI PC'. It's just a regular PC with Windows Copilot... which is a standard Windows feature anyway.

>I don't want this garbage on my laptop, especially when its running of its battery!

The one bit of good news is it's not going to impact your battery life because it doesn't do any on-device processing. It's just calling an LLM in the cloud.

This article is so dumb. It totally ignores the memory price explosion that will make large fast memory laptops unfeasible for years and states stuff like this: > How many TOPS do you need to run state-of-the-art models with hundreds of millions of parameters? No one knows exactly. It’s not possible to run these models on today’s consumer hardware, so real-world tests just can’t be done. We know exactly the performan…

also, state of the art models have hundreds of _billions_ of parameters.

It tells you about their ambitions..

LLMs are enormously bandwidth hungry. You have to shuffle your 800GB neural network in and out of memory for every token, which can take more time/energy than actually doing the matrix multiplies. GPUs are almost not high bandwidth enough.

AI PCs also have NPUs which I guess provide accelerated matmuls, albeit less accelerated than a good discrete GPU.

I’ve been running LLMs on my laptop (M3 Max 64GB) for a year now and I think they are ready, especially with how good mid sized models are getting. I’m pretty sure unified memory and energy efficient GPUs will be more than just a thing on Apple laptops in the next few years.

Only because of Apples unified memory architecture. The groundwork is there, we just need memory to be cheaper so we can fit 512+GB now ;)

Even collecting and sending all that data to the cloud is going to drain battery life. I'd really rather my devices only do what I ask them to than have AI running the background all the time trying to be helpful or just silently collecting data.
