Hmmm... This was for work so it would go in the server racks. But I'm not getting much response to the thought of having our own local AI. So probably a dead project. The V620 have gone up a lot recently, if they were back down at $300-$350, I'd probably grab one and start fooling with it for personal use, but not at $600+.
At $600+, I'd be better off buying a newer mini PC with a decent igpu and a decent amount of ram, like an M3 or M4 mini, though I would prefer if it ran Linux natively (yes I know about Asahi). Probably be in for $1000 on a decent mini PC these days, and still probably slow. But for personal use, moving along at 10t/s seems like it would be fine, as long as I can load a big enough model to get my projects done accurately. Guess I'll stick with the T740 and see when it finally doesn't keep up with what I want it to do, and then decide on the next step.
Eh....if GPU is your thing, the V620s are listing for 5-600, but in actuality some vendors will take offers for 380-420, depending on interest. That being said, smart money always look for a plan-B instead of going for the same exits as the others. Have you
considered a
V340 or a
Tesla P40 instead? The good thing about the V340 is that it's a half-witted Instinct MI50, so ROCm support (gfx900) is still there but at a steep discount (50 bucks instead of the usual 300-400). It won't win any speed awards, 16GB is barely useful and you still need the blower setup of the V620, but if you want a quick and stupid cheap way to get a 16GB card working in ROCm, that's how you do it.
I am not sure how to get that t740 to work with the V340...yet.
As for that entire "600 bucks for a mini-PC" thing, you won't be buying too much modern with it. Why yes, you can get a Minisforum X1 or ThinkCentre 75q-5 MiniPC chassis then have the onboard Radon 780M to run your LLMs, and the chassis itself is not likely that expensive (probably around 250-350)...the issue is that the DDR5 SODIMM RAM that it needs is stupid expensive (2x16GB DDR5
SODIMMs sits at 450 as of mid '26...which is more than how much I paid in mid '25 for 2x64GB), and DDR5 really doesn't give you that much bandwidth to tokenwalk well after a certain point.
So if you got a machine with 16GB of DDR5 for 450 or so (the usual price) the most you can run is an 8-10GB LLM. For 600 USD and 32GB of DDR5 RAM you can run between a 18 to 24GB LLM but the performance will depend on whether it's MoE (mixture of experts), AxB (active with a subset of parameters, like a 35 A3B is 35 billion parameters with 3 billion active) or whether you are getting a dense, "compute everything" model, like the Gemma4-27b model that's well known for being slow-ish. Even for my N5 Air (with 128GB of DDR5) there comes a point where running a very large LLM ceased to make sense, and the only thing I can do is either deal with it, fire up the V620 and let it take some of the load/use some of its VRAM bandwidth and spill out the rest to main RAM via GTT, or just fire up Claude and hope that I am not helping Dario Amodei train up the next round of bullshit dispensers by sending him training data for free.
One major benefit of the t740/t755 is that they use DDR4 SODIMMs, which can be had relatively inexpensively. 2x32GB DDR4 (max capacity) is around 300-400, which is much cheaper than 900 for 2x32GB DDR5 (still quite elevated compared to the 120-150 I paid back in 2024). I don't even think most stores sell 2x64GB SODIMMs nowadays. A recurrent project of mine is to test machines with Oculink-to-PCIe adapters to see how they behave. I was honestly not surprised when it the Oculink adapter refused to work with the t740...but I am keen to see if the same also applies for the t755.
At some point you want to pay extra for capacity AND bandwidth, which is why I suggested Apple Pro silicon (since they have more memory channels and RAM bandwidth than the normal DDR5 stuff) - The Apple used hardware tax is often cheaper than the 4x markup on new DDR5 SODIMMs.. If you spot an M4 mini or an M5 MBP14 on sale, consider it...
even if they have lower memory bandwidth their GPU compute in metal is still quite solid.
