192GB pooled VRAM beats dual-tower split

Pooling 192GB VRAM in a single tower is the only viable path for running frontier models like Llama 3 405B or DeepSeek-V3 without massive networking overhead.

• –PCIe Gen 5 interconnects provide 128GB/s of bandwidth, enabling Tensor Parallelism that is impossible over 10GbE networking.
• –192GB allows running 400B+ parameter models at 4-bit precision fully in VRAM, which separate 96GB towers cannot achieve.
• –Massive VRAM headroom enables 128k+ context windows (KV cache) on 70B models, essential for agentic "vibe coding" and long-document analysis.
• –Consolidating into one machine eliminates the software complexity of managing distributed vLLM or Ray clusters across multiple operating systems.
