Getting stupidly good results on my 4x3060ti setup.

About a month ago I was having FOMO and was going to spend coin I don't really have on new graphics cards. Instead of doing that though I decided to spend the money on a new motherboard+cpu and try to utilize my 3060tis I had lying around from my old crypto miner. Yes, I probably could have just sold the cards, but that would have got me what, $1000 max? Not even enough for a single 3090. So I built my 4 gpu rig and have spent the past few weeks optimizing it, and found a pretty nice solution. The key is tensor parallel. Lllama.cpp does not support it, so that led me to Turboderp's wonderful work on Exl3. I was able to get about 70 t/s on this model with MTP+196k context, and it works very well: https://huggingface.co/erlidev/Swift-Qwen3.8-27B-EXL3/tree/SC_4.00bpw_H5_V6 Then I started getting greedy and was wondering if something better was out there. I found the HyperQwen repo which is meant for Ampere cards, and thankfully it supports TP=4 https://github.com/syv-ai/HyperQwen So with my new Vllm setup I then found this model which is "The syv-ai/qwen38-27b-rtx3090 fast-variant serving shape of ukisai/Swift-Qwen3.8-27b (the "reduced reasoning" finetune of Qwen3.8-27B), built entirely from Swift's own weights and outputs:" https://huggingface.co/liamwh/Swift-Qwen3.8-27B-W4A16-syv-fast The results? At bf16 I can get 150k context window with about 120t/s. If I quantize kv8 it opens up the context to full 262k, but the speeds drop to about what I was getting with Exl3, around 70ish. In summary, four 3060tis with a measly 8gb vram each, power-limited to 110w, and I can get either 1 agent blazing along at 120 t/s, or 2 concurrent agents with a big context window. Oh and concurrency has barely any slowdown at all. Thank you for coming to my Ted Talk.
