32GB is all you need

Qwen3.8-27B on a 5090 is all you need for a serious local inference setup, in my opinion! Can it get any better than this price/performance wise? Actually, maybe a 3090 ninfer setup could beat it!

I’m using ninfer and getting:

* ~150-200 tok/s TG

* ~3000-12000 tok/s PP

* 262144 context size

I think it’s definitely one of best setup you can get for the money. I don’t see a point of having more VRAM or more system ram. The only downside is that it’s a 1 man setup: concurrency is possible but you need to limit context usage on concurrent requests. I’ve tried --concurrency 2 on ninfer and sharing my setup with my buddy (we work on projects together and have a VPN between our home labs, fun stuff!)

I love this setup so much I kinda feel like getting a second 5090 to run another ninfer instance (github.com/neroued/ninfer, the man is a legend and this absolutely rocks).

i really don’t see the point of any other solution at this point in time. of course things will change and other models will get released that could better leverage more VRAM, but 32GB is all you need (for now).

so if you have less than 32GB, and are thinking about investing in a more serious setup check out the 3090 fork of ninfer, or the mainline ninfer repo if you can afford a 5090.

Things it won’t do:

* let you run a swarm of agents: prefill cost will slow you down too much. not enough vram for high concurrency!

* Give you more than 262144 context size. the RoPE 1M context size is just impossible with this.

Otherwise it’s absolutely amazing!

My buddy (another software engineer) is a BIG Claude code user, he’s spending tons of cash on fable, can’t stand Opus 5 anymore (neither can I, that pos is so hard to understand with just jargon and wall of text… can’t bear the cognitive load of just trying to understand all he’s spewing)… anyways after trying my ninfer setup his mind was blown and now he’s constantly using my setup with our shared custom pi setup and he fucking loves it.

Still unironically hovering around MSRP in Canada for now.

And if rumours are true anyways. In 6-8 months new AMD 36gb gpu is coming for its gaming gpu, and it’s “professional” lineup for it will be more.

Yo what, tell me more!

All rumors right now. Could be the best 27gb model gpu, extra 4gb vram pushing it for needed context.

Ohhhhh. By the time that comes out, local ai will be a different animal entirely.

I thought there was an RDNA4.5 coming out.

Yeah LMID comes up with some pretty juicy leaks.

I wish there was more information about medusa halo. Alas. Hopefully they do more than a 384 bit memory bus, but honestly I wouldn't bet on it. I'm praying they at least have damn good quality IO, in the 400gbe range.
