• "Max clock frequency" of 2.75GHz

• PlayStation 4's operating temperature is listed as being being five and 35 degrees Celsius, which is cooler than the PS3's 45-55, exceeding 60 results in Yellow Light of Death

• PS4 to weigh around 2.8kg

 

2.75GHz Certainly packs a lot considering it's 8-cores and 35 degree's Celsius max.

Nice to hear it probably won't have the same overheating problems the PS3 had.

That's not the CPU clock speed chap.

I know its dev kit clock speed

Giod old ign, constantly doing its best to make sure its reasership stays stupid and misinformed.

Processors in closed environments are typically kept at half or a little over half of their max frequency (this freq is not the one disclosed to the public) to obtain the stable desirable thermal/power envelopes described by sony in that very peice.... And to avoid the 360 and even ps3 debacle.

Even then, that seems way to high for a jaguar. Sounds like Ram freq to me.

Another crapstain on your already dark brown resume ign.

Ram Frequency was confirmed to be 5500 MHz I'm pretty sure

Thats the gddr5. This is concerning the cpu.

I thought that's what you meant when you said ram lol

Yeah Sony actually gave the cpu its on little low latency pool of ram. Very smart move.

But yeah, its highly unlikely thats the cpu. The actual specifications sheet States:

'Maximum clock frequency in the system'



And game 'journalists' attempted to mislead people by adding words like 'core' into the mix, making it sound like it was referring to the cpu, while the actual specifications make no such distinctions.

Although, being that this is for fcc for equipment under test clearence, its also highly likely that that was the highest clock speed that passed the stress test before system failure.

Lots of possibilities. The only one thats not really practical is thats what the system runs at.

Thank god we have 3Dude here, informing us of the truth! Stupid IGN..

 That's separate from the Main 8 Gb GDDR5?

[3Dude]

Thats what Cerny said. Good thing too, the gddr5 would have been devastating to the cpu.

Although, now that ive SEEN the source (no thanks to ign) Im pretty sure thats just the results of the 'equipment under test' er, test.

When it says maximim clock speed, it means maximum clock speed, literally, as in go higher and face meltdown.... And im not entirely sure its referring to the cpu or gpu, it IS the fcc.

Devastating in a good way or bad? I think i read before that some CPU company, I'm pretty sure it was Intel, was doing the same thing with multiple samples of conventional RAM instead of on-chip eDRAM and eSRAM, and implemented it on a low latency MCM as a cache. GDDR5 maximized performance the best.

Bad way. Gddr5 latency is absolutely horrible, so its no surprise at all it would see the maximum performance boost of putting it on die via mcm. It has tge most ground to cover.

Also, im now positive this 'max clock frequency' is referring to the wi fi.

I wasnt sure at first if 'fcc' was the same old federal communications committee' and 'journalists' were just completely incompetent, or if some new 'fancy computer corp', or a new subdivision of fcc that tested more than commo, or something else newer i didnt know about ran the test.

I gave 'journalists too much credit.... Again. Its indeed the federal commo committe, and its indeed testing the communications equipment, and has nothing to do with cpu or gpu.

Yes iv'e read this a few times on a few sites.

Well, that's quite cold.

 

My laptop gets up to 80-90 degrees celsius when gaming.

No wonder my battery need servicing...
