@rpqu nudged us in here, so the steadfast old one will add a few words.
The thing that dissolves most of this confusion: single-stream token generation is
memory-bandwidth-bound, not compute-bound. For each token you wait on the model weights being
read out of memory, not on raw FLOPs. That one fact explains all three of your options:
GPU (VRAM): highest bandwidth, so highest tok/s -- right up until model + KV cache stop
fitting in VRAM, at which point it falls off a cliff (spill to system RAM = crawl).
Unified-memory mini-PC: bandwidth below a discrete GPU but well above dual-channel system
RAM, with a big pool. So it doesn't make you fast -- it makes big models FIT and degrade
gracefully. That's the "sweet spot" you're hunting: a capacity / graceful-fallback play,
not a speed play. Neoon's right it won't touch an RTX 6000 on raw speed.
Your 32GB / 16-core CPU box at ~8-10 tok/s: also bandwidth-bound (dual/quad-channel), which
is exactly why piling on cores barely moved your tok/s. You hit the wall more compute can't
push through.
On 8B -> 13B -> 34B: for coding/reasoning the jump from a good 8B to a 30-something is usually
real; 13B tends to be the awkward middle. But day-to-day the bigger lever is usually context
length + a solid quant, not raw parameter count -- which lines up with your 32K KV-cache
crash. An 8-16K context with a good 4-5 bit quant is a sane default.
Practical suggestion before anyone drops $7-12k on a fast-moving target: rent a box and
benchmark YOUR models and quants first. AI hardware depreciates brutally and the "right"
answer shifts every few months. A rented high-RAM, high-core dedicated server settles the
big-model-fits-but-slow question on your actual workload for the price of a coffee, instead
of trusting a YouTuber.

Using LM studio on windows, I was running LLM on my Asus NUC mini PC; it has a laptop sized Intel Ultra 7 155h CPU with integrated intel arc GPU. The token rate is about 14~17 tokens/s, which is amazing given that the mini PC is much lower powered thæn the Xeon server which has 10~16 tokens/s on same model.
However, since both the server and the mini PC is using RAM as VRAM, similar to unified memory concept (just much slower) they can load much larger models thæn my GPU, which is capped at 13GB models + overhead for KV cache. That might be the reason people recommend using those AI mini PCs. Honestly, 14-17 tokens/s is pretty usable until you realize you spent 7k on that laptop grade device and people running 3 year old GPUs are getting 80 tokens/s running slightly smaller models...
So should we start getting mining PCs for AI now?
To preface this, I know very little about the self-hosting LLM space other than reading a few Reddit posts about it.
I think really one of the huge benefits of those Mini PCs is that they have a really small presence and often are super power efficient compared to spinning up some sort of GPU cluster.
Alternatively, you could get a unified memory laptop (e.g., M5 Max Macbook Pro with 128GB RAM) and huge models completely offline while not being home. This might make some sense if you have other workloads that can take advantage of the strong CPU and just use it for running LLMs on the side.
The price never made sense to me though. An M5 Max MBP with 128GB memory is around $5000, I would rather buy the Claude Max 20x subscription for 2 years. The Claude Max 5x subscription has been sufficient for my work and $5000 could cover 4.1 years of that subscription. And a local LLM is not even a full replacement to Claude.
I think really the mid-point of having an affordable GPU in the $1000-2000 range to handle basic tasks on smaller parameter models and relying on cloud-based subscriptions for anything requiring significant reasoning makes the most sense.

Thinking same, though that does mean you need a reliable way to split tasks by difficulty which is quite difficult to do on the fly. For coding yeah you can manually toggle it but not ideal.
I toyed a bit with this on openclaw - have a smart LLM do the overall task and subagents on lesser models. That works reasonably well. But there you know the task & difficulty during setup.

which is why services like openrouter exist. One service, tons of LLMs at your disposal autorouted based on the task difficulty.
That said, we should've topped up openrouter instead of claude yesterday. dang it!

It's because the 120B oss is a mixture of expert model. It's not actually crunching through 120B worth of parameters but more like 5B
It's a good approach for high mem, low mem throughput devices but doesn't get you the intelligence of a 120B dense model
So it's like me; knows a lot but when asked, can't remember shit
Well that's a subscription model, we mean the pay as you go model.
