OMEGA Citadel E2 — Dual Forge

The Citadel E2 doubles the GPU power of the E1 through NVIDIA NVLink 4.0—the same high-speed interconnect used in NVIDIA's own DGX systems. Two RTX A6000 Ada GPUs share a 96GB unified VRAM pool at 1,800 GB/s aggregate inter-GPU bandwidth, enabling models that exceed a single card's capacity without tensor-parallelism overhead.

The 48-core AMD EPYC 9454 processor delivers enough PCIe lanes and memory bandwidth to fully saturate both GPUs simultaneously. 512GB of ECC registered memory ensures multi-tenant workloads never contend for system memory.

This machine runs 70B models at full BF16 precision across both GPUs simultaneously, or a single 120B model in the unified pool. It's the inflection point where one server starts doing the work of a small GPU cluster.
