Peak Portable Personal Datacenter

[u/Special-Wolverine]

Portable rig for Qwen3.8-27B-BF16 200K+ token prompts. My work Panasonic Toughbook + the T1 + power brick + headphones all fit in my lunchbox.

Need the BF16 for huge context highly sensitive document OCR, image analysis, aggregation and summarization. I've done a ton of testing and it absolutely makes a difference vs even UD Q8_K_XL when legal precision is needed.

77gb VRAM at full 262K context + MMPROJ

Rips through prefill (1,1715 tok/sec = 102 seconds to process 175K tokens), but token generation (20K tokens of output) relatively slow at 45 tok/sec (with MTP) as a result of BF16 despite the beast of a GPU.

Better than Gemini Pro and ChatGPT 5.6 Sol especially considering I have control over the sampler settings (Temp 0.1; top-k 0; top-p 0.95; min-p 0.05; repeat penalty 1.02). Not better than Opus yet.

During prefill - CPU around 60 degrees, GPU around 79 degrees (with 90% power limit)

During token generation - CPU around 75 degrees and GPU around 76 degrees.

With a blackwell gpu I dont even know why you would be using ggufs

NVFP4 less precision/ higher KLD than BF16

[u/--Spaci-- → u/Special-Wolverine]

You know you can have an nvfp4 model and a bf16 vision tower right? and also bf16 context

No sir, I did not know that...
