Why warranty and after sales matters on the Zen 4

Consistency across batches matters more than peak performance for Zen 4, and warranty and after sales is where inconsistency first appears.
Spare parts availability matters more than warranty length in practice.

Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (90 units) | Tier 1 | 7-12 days |
| Pallet (851 units) | Tier 2 | 30-45 days |
| Container (15332 units) | Tier 3 | 21-30 days |
