To summarize the article:
1.) Lower manufacturers cost
2.) Lower power consumption (Uknown significance)
a.) With lower power consumption generally comes lower temps
3.) Over engineering for the first models has been removed, as they are no longer needed
Article:
About the new model number CUH-1100 series of PS4 was released on October 9, I tried to examine the changes from the initial model CUH-1000 series.
Power consumption
Standby mode even when operating in the new model CUH-1100 and (retrofit already SSHD of 1TB) initial model CUH-1000, there was a difference of ± 1 ~ 2W in each state but power consumption was about the same.
Weight
CUH-1000 is 2.70kg 2.75kg, is CUH-1100 at scales that can not be measured only in 50g units.
Substrate
CUH-1000 is SAB-001 is CUH-1100 in the SAA-001 revision of the main board.
SAB-001 substrate A surface
SAB-001 board B surface
Board layout is almost the same.
Big difference in the power supply circuit part, a power supply circuit that was 4 phase to two-phase for GPU for the CPU in CUH-1000 is now the CPU for Phase 1 GPU for 3-Phase In CUH-1100.
It has become a "CXD90026AG" from "CXD90026G" is the model number of the APU.How would such as post-processing change or stepping change because there is no change to the numeric portion.
From "A01-COL" model number for booting the system controller (Renesas R32C / 118) is in "A02-COL". I think the change in the program that is masked.
It has become a "K4B2G1646Q-BCMA" from "K4B2G1646E-BCK0" is SDRAM that is connected to the sub-processor "CXD90025G".
It seems to be DDR3L corresponding to 1.35V to 1.5V except From a model number, but the operating voltage is unknown.
CUH-1000 (SAA-001) APU CXD90026G
CUH-1100 (SAB-001) APU CXD90026AG
CUH-1000 (SAA-001) SystemController A01-COL
CUH-1100 (SAB-001) SystemController A02-COL
8-bit MCU "STM8ED" of STMicroelectronics, which has been connected to the sub-processor "CXD90025G" in SAA-001 has not been implemented in SAB-001.
This MCU seems to pertain to the BD drive and from the wiring, but the same stone because it is also implemented to the substrate of the BD drive, stone of the main body side Maybe it was unnecessary originally.
STM8ED is unimplemented pattern while remaining
• Power supply unit
It is 24g lighter, rated output value has changed.
CUH-1000 ADP-240AR weight 472g
CUH-1100 ADP-240CR weight 448g
Heat-dissipating unit
Fin shape of the heat sink has been changed.
Shield weight 324g heatsink and CUH-1000
Shield weight 298g heatsink and CUH-1100
The CUH-1000, in order to cool efficiently at a flow rate of the wind varies depending on the location, it is a heat sink which employs a fin of different pitch at the high-speed range and the low speed range of the wind in that single it is omitted in the CUH-1100 It has become a fin pitch.
Other, there is no significant design changes gasket use part of the electromagnetic noise is or has decreased groove for hooking the internal antenna cable to the radio or have been improved but small improvements in order to enhance the workability and cost down is seen in various places You.
Even though with a model which aimed at the cost down to review the parts overkill feeling inherent in the initial model.
