Le coût d'un Kindle 4 ?
10 octobre 2011
Longtemps que j'essayais de regrouper des informations sur les différents composants avec leurs coûts respectifs. Le BlogKindle a été bien plus loin que moi avec un récapitulatif poste par poste du coût d'un Kindle:
"The component list is based on the disassembly I mentioned:
- 6″ E INK Display – ED060CF(LF)T1 REN60B7075(C62)
- ARM Cortex-A8 CPU – MCIMX508CVK8B N78A 8TFC1130E
- WLAN 802.11 b/g/n – Atheros AR6103T-BM2D 26AR0620.142D PAF284.1B 1126
- Flash – SanDisk SDIN502-2G
- Memory – Hynix H5MS2G22AFR E3M 129A
- E INK Controller(?) – Winbond W25Q40BV
- Power Management Chip – Texas Instruments SN92009 A4 TI 18IG2 AOR5 G4
- Battery Controller – Freescale MC13892AJ CQQD129D
- 30 Day Lithium Polymer Battery – 3.7V, 890mAh, MC-265360
- Aluminum Case
Some of this was hard to find. Other bits, like the Atheros AR6103T, don’t really seem to exist as far as the internet is concerned. Where necessary I’m using best guesses, product families, and superficially equivalent parts for comparison. After a bit of inquiry, here are the numbers I’m coming up with:
- Display: $48 (Based on similar 6″ E INK Displays, no bulk pricing calculations)
- CPU: $13
- WLAN: $6 (Based on Kindle Fire breakdown by iSuppli. May be cheaper here since performance matters less)
- Flash: $2.50 (Assuming similarity with previous models)
- Memory: $1 (Researched as low as $0.01 in bulk orders. Rounding up)
- E INK Controller: $9
- Power Management: $4 (Assuming similarity with previous models)
- Battery Controller $3.50 (Rounding up from $3.32/1000 units. Probably cheaper in batches of millions)
- Battery: $3
- Case: $5 (Assuming slightly more expensive than older Kindle models based on materials used)
- Manufacturing Costs: $8 (Based on iSuppli Kindle Fire breakdown)
- Other Materials: $10 (I’m sure I missed something)
- Total Costs: $113
