Where it wins, where it doesn't
Pros
- 128GB unified memory in a mini-PC chassis
- Runs models that would otherwise need multiple GPUs
- Low power draw for the capability
Cons
- Memory is soldered — no upgrade path
- Token generation well below a discrete GPU
- Pointless for models that already fit in consumer VRAM
Nvidia GeForce RTX 3090 (Usada)
The second-hand market's favourite: 24GB of VRAM around $600, and the basis of most cheap multi-GPU rigs.
Where it wins, where it doesn't
Pros
- 24GB VRAM at roughly $600 — unmatched cost per gigabyte
- Pairs well for multi-GPU rigs (72GB across three cards)
- Mature, well-understood CUDA support
Cons
- No warranty and unknown usage history
- High power draw that compounds across multiple cards
- Two generations behind on compute and efficiency
