A quick rundown of the leaks regarding clock speeds for both consoles.
The last we heard of the processor specs for PS4 was 800mhz gpu and 1.6ghz cpu. This matched the rumors and was confirmed in the Killzone dev slides from the reveal demo. Nothing since has been talked about, random rumors swirled that it may be upclocked as high as 1ghz/2.4ghz, which would drastically raise the heat generated by the console. Unless they planned this while making the first APUs to come of the line, this could lead to units that just die as soon as you power them on.
Microsoft had the same clock speeds for the Xbox One according to the rumors from 2012, but were never fully confirmed. Microsoft announced the clock speeds and claimed an upclock over their target. This was preceeded by rumors of poor yields thanks to esram and a possible downclock. (This was not a Cboat rumor, so grain of salt)
Now the rumors are of hardware instability thanks to this upclock. (Since it was probably not tested fully, thanks to the late hour it happened, the day one update enables the upclock) Cboat knows something, but won't comment until launch. (That scares me, he had no issue leaking the RROD prior to launch)
And that covers most of the rumors about both systems. It will be interesting to see what comes out of this event.
