The remaining major components found tonight include the DRAM used by the network co-processor and a Sony Computer Entertainment Inc. (SCEI) device marked only as "1327KM449." We also have Panasonic's MN86471A HDMI Communication LSI. Stay tuned as analysis continues to come out of our labs...

@anon5203197, Thanks. Will try this weekend. We approached Sony but looks like they just replace it with new one and dont repair the existing one, here in India. And for doing that they were asking for original bills, who will keep bills for 3 to 4 years :-)...and that too we bought international so they were very resistant about doing anything.
The photo of the processor shows a metal window frame around the die. This could be a stiffener, used to stiffen the organic substrate ( green ) on which the die is assembled. Such substrates are called Coreless substrates, w/o the usual PCB like Core that gives the Substrate its strength & rigidity but adds inductance to the power delivery and signal path thus slowing things down electrically. Coreless substrates are troublesome & expensive so used thus far only for high performance Servers etc. If this is indeed a Coreless substrate then would be the first use in a Game system.
Is the new PS 4 much faster than the last model ?
Would ChipWorks be interested in verifying if Sony is indeed using a Coreless substrate and Stiffener ? They just need to look at their x - sections & x - rays once again.
My Sony PS3 doesnt come up it says some drive issue, tried going to Sony's showroom and they say since you bought it from outside India we cant do anything. Also the hard drive is not available, we could have replace it ourselves.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
