I paid good money for this Dynex!
The design of the white CUH-1200 just looks amazing, so now that we have confirmation that it's quieter, I'll be swapping out my current PS4 for one of these.
No. It because the ps4 has to keep the ram powered. While they are likely some other changes that help. This is the biggest change.
50% ram chips almost 50% less power in standby.
Former process engineer/ current test/product engineer.
The power consumption reduction is likely not due to a process change. The leakage improvement is primarily due to more efficient chips using better clock and power gating techniques. Looks like Sony is getting rev01 chips from their suppliers who did minor redesigns to improve standby current.
Generally, high quality dc/dc converters will consume less than 1uA of current in standby mode. This means the internal references on these chips are "turned" off under some form of crude UVLO (undervoltage lockout) circuitry that is lower that the true UVLO for the chip.
As for package size, you can in fact put a smaller chip in a package (most of these are chip scale or quad flat no lead packages). The concern is that while the die gets smaller, the copper/gold wires from the chip bond pads increase in length in order to be correctly bonded to the leadframes. This can cause reliability issues if process is not carefully controlled (typically shorts between wires).
Sony must have not wanted to do a full blown fresh HTOL or characterization to get their hw to the market faster. I expect the next revision will be a pretty significant shrink.
This is an nice start, but I'll be waiting for the inevitable actual "Slim" model to release.
Yeah, this. Surprised some people are talking about swapping out their original model for this relatively minor update.This is an nice start, but I'll be waiting for the inevitable actual "Slim" model to release.
Much smaller board too

The move to 8 8Gb GDDR5 modules was expected, but the drop in power consumption was perhaps not.
Have they finally thrown in a 5Ghz WIFI chip in there yet?
If I remember vaguely the PS3 basically did not upgrade it's wireless module. So probably not.
Lack of 5ghz support is a big bummer. Was a bummer on Wii U too, but they have the excuse of the gamepad using that band. What's Sony's excuse.Nope, never did.
Be happy the PS4 has Wireless N. Because the PS3 still doesnt.

Nice improvements. Will be interesting with the next revision.
Has anyone tested load times with an SSD? They removed the usb3 to SATA 3 bridge right? Though I think the bottleneck is in the encryption and decryption process
I am still amazed that an ARM chip with 256MB Ram can't handle a HTTP(S) download. How far into the past do you have to go to find a chip that is that weak? Even the Cortex-M0 can do that.
64Gb GGDR5 MEGATON!!!!!=P

This seems like a pretty decent remodel, but not really any reason to 'upgrade' from the old PS4.
Might seem like an odd question but can you buy a new model and just switch hard drives around without having to re download everything?
(Having to format to the new system)
You will need to use the backup utility.
Has anyone tried restoring their PT backup/license when transferring between systems? Does it work still?
I have it still works.Has anyone tried restoring their PT backup/license when transferring between systems? Does it work still?
Thanks for the great insight.It shouldn't be hard to use an ARM chip as a programmable I/O controller that manages access to hard drive, blu-ray and network on a block level and lower network level respectively. However, in order to actually write files autonomously, the chip would have to be in charge of managing the file system. And here begin issues with OS design, since the Kernel on the APU would have to delegate the file system to the secondary chip.
This is what I thought would be the case if the secondary chip was to download / upload / install files in standby, what problems would this create? Security?since the Kernel on the APU would have to delegate the file system to the secondary chip.
Do we know the models of the new memory versus old? Going from 16 modules to 8 is not insignificant, especially if the new modules are running at lower voltage, 1.35v versus 1.5 for example (I don't know btw). Hoe many watts do ddr5 memory modules typically consume?There are many significant changes, the most important going from clamshell mode GDDR5 (16 modules, sharing address/data lines in pairs) to non-clamshell with 8 modules. Power consumption has also dropped 26W from the launch model while playing a game.
The move to 8 8Gb GDDR5 modules was expected, but the drop in power consumption was perhaps not, especially since the reports noted that the package/die measurements stayed constant. Both sites correctly theorize that the reduction in GDDR5 modules plays into it, but that alone cannot explain the 26W load drop.

I live in a condo complex with six billion 2.4 ghz networks in range, and only a couple 5 ghz. In my case, 5 ghz has cured ALL of my ills. (On devices that support it... which is everything I own other than WiiU/PS3, even devices several years old.)If you're really concerned about speed/latency you would use wired connection regardless of the wireless technology available today.

I'm fine through two walls. Ping/speed identical to wired. Not sure on the bridges. Possibly something to look into when I get a PS4.When I tried 5GHz I had to be so close to the router to get decent speeds that I might as well have wired them. Even just one wall killed the speed.
Do they do 5GHz wireless bridges? You could use one of those wired to the PS4?
Well, it's mostly because I really like the current design, particulary now that they've gotten rid of the gloss nonsense. They took care of the noise issue, so really, what's left for me to want from a Slim revision? This is the thing I want right here.
Much smaller board too
5db ain't nothin.
I think they were speculating around September for US.I was planning to go out today to get a PS4, but I imagine I need to hold out. Any info on when these revisions will hit the states?
5db ain't nothin.
Clearly Noticeable Change: 5dB
5db ain't nothin.
Does the changes count for the 'new' 500GB (CUH-12xxA) model and for the 1TB (CUH-12xxB) model?
I thought the first reports said only the new 500GB model will get the new tech specs.
Maybe not much, but 5db difference is considered:

-5dB is a 70% reduction.
dB is a logarithmic scale, they're not like normal units.
I don't really believe these sound numbers anyway, probably using using a smartphone app.
