Standout
Nvidia GeForce RTX 5090 (32GB)
32GB GDDR7 — runs 70B-class models quantised on a single card
Nvidia GeForce RTX 5090 (32GB)
The fastest consumer card available, with 32GB of GDDR7 — and the power bill to match.
Where it wins, where it doesn't
Pros
- 32GB GDDR7 — runs 70B-class models quantised on a single card
- Fastest consumer silicon available
- Avoids the complexity of a multi-GPU build
Cons
- Roughly double the 5080's price for far less than double the performance
- 600W-class power delivery dictates case and PSU choices
- Poor value for anything that is not memory-bound

Threadripper Pro + Dual RTX 4090 Build
Professional-tier workstation: AMD Ryzen Threadripper Pro with two NVIDIA GeForce RTX 4090s (48 GB VRAM total) and 256 GB of RAM. Runs Llama 3.1 405B and gpt-oss-120b at roughly 10-20 tokens/s — the enterprise end of this index for on-premises inference.
Where it wins, where it doesn't
Pros
- 48GB total VRAM for heavy inference
- Massive PCIe lane bandwidth
- 64-core compute headroom
Cons
- Extreme power consumption (1500W+ peak)
- High noise levels under sustained load
