Is it me or are ifixit teardowns becoming increasingly cheesy? They've become lame pun minefields instead of insightful info on the chips used.

According to the FCC filing for both PS4 dev kit & the retail PS4, the PS4 is supposed have Bluetooth 4.0 Low Energy in addition to Bluetooth 2.1 +EDR. So it's kind of disappointing this ifixit teardown didn't give us any info on the PS4's bluetooth radio to confirm.

well my intend for the thread was the teardown, hence the ddr3 isn't in the title. I don't remember reading anything that mentioned the secondary memory.

my booboo is complete.

I thought this was going to be about people who are playing porn on their PS4s.

I don't know, it just seems like one of the first things people would try.

Even when people know the difference they call everything by Bytes. Especially hardware. Why 2Gb? Just say it's 256MB as everyone will understand it better.

bits is mostly used for internet speeds.

PS4 has 64Gb of GDDR5 memory confirmed.

What's the point of optical audio out if your only video out is HDMI?

In addition to the other responses, there's also issues with some HDMI hubs (including the one in my receiver) where they won't pass certain HDMI signals, such as 3D video, through them. My PS3 routes video directly to my TV, and I use the optical audio to get sound from my receiver.

Surprised there doesn't appear to be any large quantity of Flash memory on board for OS use. PS4 was rumored to have 16GB on board for certain OS features. I guess the system will rely more on the HDD and keeping apps in RAM than I previously expected. Perhaps they had intended to rely on Flash when the system was going to have only 4GB of RAM, but when they went to 8GB they decided to save money on the Flash and reserve a lot more system memory.

PS4 slim:
20nm APU
8 8Gbit GDDR5 chips
Secondary chip + memory + ethernet controller + southbridge + usb controller all integrated into a single chip (memory stacked like Vita).
smaller Motherboard, Case and PSU

I read it first at chipworks but Marvell Avastar 88W8797 does support BT4.0 by itself. Why PS4 supports upto BT2.0 then...?

PS4 uses BT 2.1 because it is higher bandwidth than 4.0 (which is optimized for lower power usage), and PS4 needs the bandwidth to transmit game audio and chat to 4 controllers at the same time.

That's why it's surprising tbh.

Yeah, considering this entire last summer. But to be fair - PS4 is hot stuff, it's been hyped to the max, it's good hardware, and perhaps 2GB wouldn't have been out of the realm to get shoved in there.

Also people see what they want to see. :)

This should be pointed out, According to the FCC filing for both the PS4 Dev Kit (https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=435177&fcc_id=AK8DUTD1000) & the retail PS4 (https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=583848&fcc_id=AK8CUH100C1), the PS4 is supposed have Bluetooth 4.0 in addition to Bluetooth 2.1 +EDR. On both of those links, the info is in the last .pdf file called "FCC 15C Report". It should be on page 5.

Now that it's confirmed that the wireless radio in the PS4 is a "Marvell Wireless Avastar 88W8797", we can 100% confirm that the PS4 has Bluetooth 4.0. Here's a link for the .pdf file info on the Marvell Wireless Avastar 88W8797 SoC:

I wonder why Sony doesn't list Bluetooth 4.0 as a tech spec feature on the PS4.

Can someone PLEASE create a new thread for this WSJ article:

Sony May Gross About $100 Per Console, Teardown Shows
By DON CLARK

Sony is doing a lot of things differently with PlayStation 4 and there seems to be a payoff, as highlighted by an early analysis of the new device’s innards.

TechInsights, one of the first companies to take apart the console, estimates the cost to Sony of its components at about $296–indicating a gross profit of nearly $100 on the $399 product.

That’s quite a different picture than the firm painted after Sony came out with the PlayStation 3 in 2006, which then carried a list price of $599. A TechInsights teardown report at the time estimated the cost to Sony to build the console totaled more than $688, indicating it was losing about $88 per console shipped.

The contrast underscores changes in components and their cost as well as key design decisions Sony made this time around.

For example, Sony opted to use a Blu-ray drive in the PlayStation 3, a then-pricey component that TechInsights estimated cost Sony $81. The same kind of drive costs $20 now, the firm estimates.

But one of the biggest differences this time concerns processor chips. Sony with PlayStation 3 went with the nonstandard Cell chip, developed in collaboration with IBM and Toshiba, which required a separate chip for graphics. That combination, along with accessory chips and related memory, accounted for about $154 of the PlayStation 3′s total cost, according to TechInsights’ estimate at the time.

Making software for the Cell, by all accounts, also caused programmers to tear their hair out.

“The developers found it really tough to come to grips with,” recalled Dominic Mallinson, a vice president for research and development for Sony Computer Entertainment America, in a presentation Wednesday. Issues associated with programming the chip “caused the complexity and the cost to rise dramatically.”

Mallinson, who spoke at an event hosted by chip maker Advanced Micro Devices, said Sony listened to developers this time in a number of areas. For one thing, it went with an AMD chip based on the x86 design familiar to people who write PC programs.

That eight-brained chip, customized with input from Sony, also delivers the PlayStation 4′s graphics capability. TechInsights estimates the processor in the new console cost Sony $85.

But perhaps the thing programmers will be most excited about is the memory in the new console, Mallinson said. Not only is there a lot of it–eight gigabytes–but the chips used are a variety called GDDR5 that offers extremely high bandwidth in sending data to the processors.

In addition, where the PlayStation 3 had separate pools of memory for graphics and for the main processors, the memory in the successor device is one unified pool that can be used for either function, Mallinson noted. (The associated chips add about $62 to the cost of making the new system, TechInsights says).

The technology choices, overall, aid performance and cost at the same time.

“We selected components and semiconductor processes which are very mainstream which will allow us to hit those very aggressive cost targets and to cost reduce over time,” Mallinson said.

IFixit and TechInsights, in that order, both published heavily illustrated teardowns Friday. The former firm doesn’t provide cost estimates, but revealed some of the key chip suppliers in the system.

They are primarily known players. Samsung, for example, supplied the memory. A less familiar supplier, Macronix, provided some serial flash memory. The hard drive comes from HGST, a company based in Japan that is now part of Western Digital.
