Sony PS4 dev kit FCC filing shows off extra ports, 2.75GHz max clock frequency 

Sony proudly showed off its PlayStation 4 hardware for the first time at E3, and now we're getting a peek at what developers are working with this generation thanks to the FCC. The DUH-D1000AA prototype Development Kit for PS4 is listed in these documents, tested for its Bluetooth and 802.11 b/g/n WiFi radios. As one would expect, the diagrams show it eschews the sleek design of the consumer model for extra cooling, a shape made for rack mounts plus extra indicator lights and ports. Also of note is a "max clock frequency" listing of 2.75GHz, and although we don't know how fast the game system will run by default, it's interesting to hear what all that silicon may be capable of (as a commenter points out below, that may relate to the system's 8GB of GDDR5 RAM) while maintaining a temperature between 5 and 35 degrees celsius. Hit the link below to check out the documents for yourself, after seeing this and the system's controller become a part of the FCC's database all we're left waiting for is Mark Cerny's baby.

It would be nice if late into the generation Sony  could increase clock speed of our PS4 via firmware update to boost performance of games.. :D! dream on

all i want is them to ad 1 USB port to the back so the camera doesn't have to be connected to the front. i hate wires

Wasn't the PS4 rumored to run @1,6GHz by default? If this boost is also achievable in the final product I'll be happy^^

lol looks like the xb1 with more i/o

AFAIK PSeye will connect in AUX port behind.. not in USB!

That is likely the RAM clock, noted for FCC RF shielding requirements.

That's pretty fast considering there's 8 processors

There's a reason why devkits are often clocked faster. Debug layer.

I don't think this poses any potential for it to move to retail systems.

"Maximum clock frequency in the system" what does that refer to? CPU? x264 encoder? ARM core?

DevKits needs to run at high clock than final product due DevTools/Debug overhead.

But I think it is safe to expect a clock close to 2.0Ghz in the final product if there are any boost.
