So we are sure that this is about the CPU clock frequency? I am not up to date with the devkit thread.
If that would be true it's only the better


It has nothing to do with CPU clock frequency :)

no! its not clear if its ram or CPU.. that stuff is still in the air, we still dont know at what speed Ram will be, so people can associate it with RAM

Bwahahaha! Really? Guys misunderstood it the first time and now a thread like this is started, fantasysing a 2.75 ghz clock while totally ignoring that nowadays computers have several clock-sources.

really thats how u start an argument.. if not intelligent, atleast make it interesting.

Good lord, we had this idiotic thread days ago.. So for you, spelled out once again.:

The FCC doesn't care the least what your cpu,gpu,whatever is in your box. The FCC  cares about the high frequencies your gadget might emit and requires the maximum frequency to be stated. It just happens that the two gddr5 forward clocks are 2.75GHz (double the base 1.375GHz command clock). This is the maximum clock frequency of the PS4 on any bus and hence defines the maximum clock that emits hf.

Got it ?

If the max clock rate refers to the CPU, then I'd imagine it may be something that works like Intels turbo boost, but AMD's version. For example the I7 3930k stock clock is at 3.2Ghz, but it can clock it's self up to 3.9Ghz if required and only if the CPU isn't near its peak TDP.

If this ends up being the case, then it'll probably help with non gaming apps, and OS related things. It also may be used by games, this would explain why the overall TDP is much much lower than it was on the PS3, which had a TDP of 200 watts.

Thats my guess.

Think its the clock rate of the gddr5 ram.

It has already been said several times that it is the frequency of the gddr5 ram: 2.75GHz * 2 = 5.5GHz

This thread should be closed.

You are such a nice guy. You explained this so calmly and friendly to him. ¬_¬

For a GDDR 5 @ 2.75 GHz with a card equivalent to 7870 its pretty low.. that's almost half the speed of 4.8 GHz which 7870 runs on..

Not that this changes anything, since the reason for the frequency has been correctly explained in this thread, but look at the dimensions and weight in the paper. This is the retail unit. :) The part that says manufactured in Japan/China is interesting, as well as the fact this already exists. We should be talking about that instead... :|

So it seems like even the retail PS4 unit will have the capability to be clocked at 2.75 GHz. For sure it will be underclocked at 1.6 GHz.. but for future that window can widen with a firmware upgrade.

Sony's PS4 dev kit passed by the FCC roughly a week ago, and now its consumer-oriented counterpart has passed through Uncle Sam's offices. Not only do the federal documents show the consoles' polished exterior, but they once again note a "max clock frequency" of 2.75GHz, teasing just what kind of horsepower sits inside the black parallelogram. Though there isn't much more to note in the agency's files, a duo of system labels marked with "Made in China" and "Made in Japan" hint that Hirai and Co. will be manufacturing the hardware in both those territories. Mark Cerny's wunderconsole won't be hitting store shelves until later this year, but it already has the appropriate paperwork to make the trip stateside.


Am I missing something?

It says the dev kit has that maximum clock frequency. What does that have to do with the retail box?

2.75Ghz is the max GDDR5 clock

My comments from the dup thread.

What that mean? The PS4 final version (not the devkit) is ready to launch in October or even early... a GAFer said that PS3 passed in FCC in September 15, 2006, so the PS4 is two months ahead.


Everything is doing right for the Sony this time
