Swap Alternatives
- GPU: NVIDIA RTX 6000 Ada Generation — Single-GPU alternative (no tensor split, simpler): NVIDIA RTX 6000 Ada Generation 48 GB at $6,799.
- RAM: Corsair Vengeance 64GB (2x32GB) DDR5-6000 C30 (AMD EXPO) — More headroom: 64 GB DDR5-6000.
- Aya Expanse 32B at Q8_0 needs more VRAM than any single consumer GPU, so this uses 2× AMD Radeon RX 7900 XT (40 GB pooled via tensor split) — cheaper than the single NVIDIA RTX 6000 Ada Generation (48 GB, $6,799) that would also fit.
- The AMD Radeon RX 7900 XT is a tight fit at Q8_0 — consider an upgrade alternative for KV-cache/context headroom.
