Self-hosted Qwen3.8-27B on 2× RTX 4080 Super ( 2 x 32 GB VRAM) — 152 tok/s, ~1 EUR/hr

Just got Qwen3.8-27B (FP8) running on rented GPUs from Trooper AI. FP8 fits on 64 GB VRAM with decent results.

Stack:

- GPU: 2× RTX 4080 Super Pro (64 GB VRAM total)

- CPU: 12 P-cores, 76 GB RAM

- SSD: 900 GB NVMe

- Price: 1.06 EUR/h

Served it via vLLM → KServe → Envoy AI Gateway, TLS + token metering + rate limiting on top ( I already have a running Kubernetes cluster, I attached to trooper GPU node), or you can it serve it directly with compose if you are a single user.

Runned load tests: (10 concurrent requests, 32768 context)

- TTFT: ~0.9s

- Per-stream decode: ~28 tok/s

- Aggregate: 152 tok/s

Now, looking to deploy the full model FP16 on RTX 6000 Pro
