PlayStation 4 CPU using AMD Turbo Core to go from 1.6GHz up to 2.75Ghz ?

For awhile there has been speculations about the 2.75GHz clock rate that showed up in the PS4 FCC Certification. Some speculated that it was just the clock rate of the Memory but today in a IGN PS4 review video the 2.75GHz clock rate has been shown to be the highest clock rate of the CPU with 1.6GHz being the base clock rate.

Hmmm I'd think it would become too hot but good for PS owners if true

Pope_Kaz_Hirai_II1040d ago

Doubtful but would be awesome if true.

cleft51040d ago

It's interesting how most of the stories about the PS4 is about how their is all this power in the console that wasn't even mentioned. That's the best sort of surprise.

UltimateMaster1040d ago

It's based off the IGN article.

@Cleft5

Not saying I disagree with you, however, this is very much like MisterX and his theoretical 2.1 TFlops math with ESRAM.

I'm skeptical of this on both sides.

CryofSilence1040d ago (Edited 1040d ago )

@Prime157

This is much more a physical possibility. It is extremely common for multicore chips to dynamically turbocharge, even in laptop and mobile processors. My 3 year old laptop with a first gen i7 onboard is capable of it. However, to my knowledge, there is no way RAM will increase FLOPS (Floating-point Operations Per Second), just the bandwidth to transmit the data. CPU/GPU create the FLOPS count. ;)

Edit: Perhaps you are referring to how the theoretical bandwidth limit of eSRAM in conjunction with DDR3 is over 200 GB/s? That is a physical possibility, but time will tell.

ChrisW1040d ago

Yes, it can go that high... Phenomenally higher if cooled with liquid nitrogen.

Will Sony ever make a patch to make it go that high? I strongly believe not. Because all games are built around the standardized GHz for optimal performance with least amount of problems.

pedrof931040d ago

Can someone show me the original source ?

Irishguy951040d ago

Why well said for you and not for lifeisgamesok? The only reason it wouldn't be put up is because of heat. The thing about 'overclocking' is that it brings on heat. And alot of it if you clock it too high for your cooling system to handle.

abzdine1040d ago

You want a futureproof console, here you go!!
Friday 29th cannot come soon enough

ajkula1039d ago

well, the turbo core tech, as mentionned, can lower the freq. to minimal uses, then higher the freq. of all cores up to a certain speed THEN to less threads sensitive applications, reduce the number of core activated and boost those remaining to the ceiling...
in no way it'll boost all 8 cores to 2.75, this would be toasting the proc...
there must be a precise ratio here, which i have no idea.
and a real question fans should ask themselves is, at which clock speed all 8 cores ceiling??

..instead of being doubtful about things everyone ignore here!
SINCE, it is factual that the jaguar is capable of "turbo core tech"
cheers

Consoldtobots1039d ago

this isn't some secret sauce, my 4 yr old laptop has the same type of core and can do the same thing.

Don't worry, Sony are hardware geniuses, they have all that tech in a tiny box and the power brick inside too.

140 degrees F (60C) after playing Killzone SF for 3 hours straight which is very good indeed.

Sitdown1040d ago

After unboxing my ps4, it slowly became apparent how hideous the ps3...I got my ps3 fat and ugly with the full intentions of hurting it's feelings. It's place in the entertainment cabinet now belongs to another.

majiebeast1040d ago (Edited 1040d ago )

Yeah my 6870 is idling now at 45-50 degrees celsius. If i start playing a game it goes up to atleast 70.

^

Phat PS3 is the BBW of consoles.

pyramidshead1040d ago

If they designed it to withstand the heat from the CPU going up to 2.75 then holy crap. So long XB1 CPU advantage. If true....no wonder Sony kept this number quiet :P

scott1821040d ago

Why the crap don't they just say what it runs at so people can stop with the rumors?

Themba761040d ago

my laptop runs hotter than that my laptop can get up to 91c

mkis0071040d ago

My pc rig with an oc'ed i7 920 3.6 ghz aa gtx 680 a gtx 660 and cooling with a corsair h70 has my temps at 40-50 C idle...heat is not going to be a problem, no matter how much people want it to.

In game those jump to around 64C

mxrider21991040d ago

i played for 29 hrs straight no over heating issues at all i was streaming too

ajkula1039d ago (Edited 1039d ago )

@scott182: simply because from their point of view AND a business intelligence point, it's none of yours business and you should care about the game quality first when you first think of buying an entertainment hardware, not the specs inside it...
if you remember the jaguar from atari, which had a dual highly capable processors for its time BUT also embended an old motorola 68000...
...that the devs preferdd to use from laziness...
whatever, just think in their place!

Consoldtobots1039d ago (Edited 1039d ago )

good stuff!!!

I use mine in landscape mode and it looks like that runs 10° cooler at peak.

ZBlacktt1039d ago (Edited 1039d ago )

Yes, this is why they have sold the most consoles on the planet. Why they come out with Slim and Super Slim lines!

Nice avie. I went to that concert in 86. Got a picture wearing the shirt from back then if you want to see it for the laughs, lol. Still and always metal to this very day!

\n/ o.o \m/

But yeah, I've played ACF up to 10 hours a day. Not a single issue as expected. That's playing for hours. Go eat, leave the console on... continue playing.

GarrusVakarian1039d ago (Edited 1039d ago )

@ZBlacktt

Man,i can't even express how jealous i am of you. Seriously huge Met fan here. I saw them last year, going to see them again whenever they come back here. They played so fast in 86 from the youtube vids, it was like 2X tempo.

Yeah PM me the pic lol (you have me on block though btw)

What great rumor and it will forever stay a rumor.

C-H-E-F1040d ago

Didn't they say something about a surprise upon opening up the ps4? Is this it? If not then ehh I guess i'll have to continuing playing Killzone Shadow Fall and 2k14 plus the other games I bought until someone unlock the surprise for me because frankly i'm to lazy to do it myself. :D

JsonHenry1039d ago

Too hot? It is under-clocked already from its typically stock running speed. My 8-core AMD CPU in my PC runs pretty close to this same pattern. It idles lower then when a game or application that is more demanding is started it jumps from like 3.6ghz or something to 4.2ghz.

Its pretty standard these days for AMD CPUs. Whether the PS4 does this or not I don't know. But it wouldn't be much of a stretch to say it is possible since the rest of AMDs desktop/laptop line up of CPUs all do this all day every day and have for a long time now.

Kleptic1039d ago (Edited 1039d ago )

^exactly...This shouldn't be too surprising...both AMD and Intel have base clocks with 'boost' multipliers when applications call for it...

thermal management is the only question...and considering jaguars are low tdp, low heat units to begin with, i'd be very surprised if a turbo setting of 2.75 makes some outrageous difference in heat output...

however, people need to keep that in context...a cpu's frequency has zero effect on its instructions per cycle limit...and jaguar cores are horrendously bad in this area (not a big deal for a console, as the OS is simple)...but having very low IPC figures do not get very tangible differences from overclocking...

So...just saying...this could be true...but even then, you'd never know the difference...the cpu's between the xbox one and PS4 will perform nearly identically, even if one is clocked slightly differently...

the new consoles are gpu-centric devices, any performance differences between them will ALWAYS be because of the gpu differences...

Cernunnos1039d ago

People forget that turbo only applies to one core. So the other 7 cores will still run at 1.6ghz. That's why the heat output does not increase significantly.

frostypants1039d ago (Edited 1039d ago )

Yeah...most processors can technically be overclocked beyond the speed they are initially set to. However the clock at which they are set tends to be below capacity in order to maintain safe operating temperatures. That's why when PC modders OC the CPU, one generally also throws in all sorts of additional cooling mechanisms...more fans, better thermal paste, bigger heat sink, etc. Sony won't bump the clock speed of this processor...even if later batches of the chip are more capable of managing it safely, they wouldn't fracture the capabilities of their install base that way.

ipach1039d ago

theoretically, the non-used cores partially help dissipate some of the heat and enable the chip to operate at those speeds. that's how it works on their PC CPUs at least

BallsEye1039d ago

It alrady heats up over 60 degrees at normal clock. Why would anyone belive it can go up from 1.6 to 2.75 without overheating?? You guys are unbelievable.

Madderz1039d ago

Says the guy with 2 bubbles.

BallsEye1039d ago (Edited 1039d ago )

@Madderz

Bubbles on n4g only mean if you're a hardcore sony fanboy (tons of bubbles) or not (almost none) it got nothing to do with facts or truth.

http://www.neogaf.com/forum...

You can read numbers, right?
61 celsius - 141 f after 20 mins of KZ

now where is my bubble up for stating a fact? According to you I should get some.

RegorL1039d ago

1) 60 degrees is not a problem unless you put it in a box, resulting in 60 degrees air intake...

2) How do you know KZ runs on normal clock?
If any game might utilize boost already it is KZ...

All modern processors do "turbo" for reduced core processing, been around for ages...

Sm00thNinja1040d ago

^^^^^ this man is correct

indysurfn1040d ago

he made two statments only one of them is correct. It has been around for ages, but not all modern have turbo, not all by a longshot!

frostypants1039d ago (Edited 1039d ago )

No, he isn't. In processor terms, Turbo is a marketing term, not a technical one.

Statix1040d ago

Not in consoles. Everyone assumed that the CPUs in these new consoles just ran at a fixed base clockrate.

R1V3N1040d ago

assumed, key word. it would be like the multi threading in my laptop 2.8 ghz single core apps 2 ghz for all multi threaded apps

Volkama1040d ago

Indeed, turbo generally downclocks other cores to boost a single core. On a PC this is a way to get better performance from programs that hammer one thread alone. It is of limited use in the consoles where you'd expect games to be properly multi-threaded anyway.

Still, additional options for developers can't be perceived as a negative.

NarooN1039d ago

Turbo boost as a concept has been around for a long time, but not all modern CPU's support it, not by a long shot. There are more CPU's than just x86 Intel and AMD processors, and not even all modern Intel/AMD chips support it.

ATiElite1040d ago

And it's less efficient and less powerful than an Intel so who cares.

Not really talking about the PS4 but just AMD cpu's in general

DragonKnight1040d ago (Edited 1040d ago )

Why do you make pointless comments like this?

NarooN1040d ago

What do Intel CPU's have to do with this, lol? Absolutely nothing.

indysurfn1040d ago

Since we are comparing xbox one to PS4 I have to wonder. You do know that Microsoft has the same brand cpu in the xbox one dont you?

You said not 'really' talking about, but if that was true you should have said not talking about xbone, and PS4. But you didn't.

LordDhampire1039d ago

No they don't microsoft might be based off same processor but since they added esram to the die it would produce to much heat

Magicite1040d ago

have u made benchmarks on it so u can prove your point?

Persistantthug1039d ago (Edited 1039d ago )

ATiElite makes pointless comments like these as his little subtle attempt to jab at consoles.

He's been angry for years with how consoles continue to get first class treatment, while PC gaming is relegated to second class treatment among the AAA budget developers and industry.

ATiElite is a bitter gamer and bitter n4g member....... basically.

ATiElite1038d ago

Ha ha your too funny! AMD's suck NO MATTER WHAT THEY R IN!

http://www.n2g.us/2013/11/g...

there goes your second class right there!

PC we play games NOT talk about them!

Persistantthug1038d ago

You're not playing GTA 5.....not on your PC.
Rockstar treats PC gaming as if it's second class.

Sorry.

ATiElite1038d ago

How?

what Game besides Red Dead has NOT been on the PC from Rockstar?

GTAV PC will arrive when PS4-XB1 versions arrive.

your statements are so DUMB. Do you even think before you type....apparently NOT!

Persistantthug1037d ago

Even if Rockstar does eventually bring GTA 5 to the PC, it would still be late, and thus, SECOND CLASS treatment.

Rockstar doesn't even care enough about PC gaming to be bothered bringing it on time.
Rockstar isn't the only one either.
I'm sorry but it is what it is.

ATiElite1037d ago

is GTAV on PS4 or XB1 right NOW?

NO

So PS4 and XB1 are second class too right according to YOU, you stupid idiot.

you are so friggin STUPID! stop talking to me and go away. go play TLOU for the 99th time as you don't even have a PS4 yet.

GoldenMonkey351040d ago

Would it make a difference? the console is still underpowered just like the xbox one. I give the wii u a pass just because Nintendo seems to be the only one out of the big 3 to understand consoles cant compete with the pc market on trying to make super duper graphics and all that other stuff sony and ms try to brag about. Instead they focus on an affordable console that can make nice clean graphics with super fun games focusing on gameplay.

Orbilator1040d ago

really? i have yet to see gears3 or killzone 3 beaten apart from res on a pc so stop talking utter nonsense

Jovanian 1040d ago

"i have yet to see gears3 or killzone 3 beaten apart from res........... and framerate and texture quality and anti aliasing and performance and tesselation and DX11 features and aesthetic"

Fixed that for you. Look at any high spec PC game and you will see it beats those two games in pretty much all categories I listed. Same for pretty much every other PS4 or XB1 'next gen' game which can barely handle 1080p and barely meet 60 fps, PC standards since for like a decade

starchild1040d ago

That's because you are blind or looking through special fanboy goggles. Even the best looking games on PS4 like KZSF still don't look as good as the better looking games on PC.

Gears 3 and Killzone 3 look very poor compared to the best PC games.

Statix1040d ago

They may look better, but Killlzone 3 or Gears of War 3 do not look "poor" by any means, even by today's standards.

solidboss071040d ago (Edited 1040d ago )

Guess what. I spend a few hundred on a great console, and I am set for nearly a decade (PS4). I like women, sport and other things that require money, like life. I don't need to spend thousands just to up the resolution on a PC version of a console game.
Wow, look! I am playing 6 different WOW games at once on my amazing rig, while I4 internet pages are open...... yeah...... that's great, why don't you step outside and make some Vitamin D?

JsonHenry1039d ago

Then, Orbilator, you know NOTHING of PC gaming. Because those games were beat BEFORE they came out on the console of choice. (in terms of graphics fidelity, I'm not speaking as the "fun" factor of the games)

Crisis proves graphics isn't everything.

Jovanian 1040d ago

ah yes...the classic sony response when they are called out on their hypocrisy for championing graphics when comparing their hardware to the XB1, but suddenly having a complete reversal in opinion when comparing their hardware to even a medium spec PC. I don't think I'd be able to handle that kind of dissonance

ThatCanadianGuy5141040d ago

Ah yes, the old PC fanboy wet dream of elitism, compare a machine that swaps specs at will vs a console with fixed specs.Even tho we all know it makes no sense, let's do it anyways to make us feel better about that $400 we blew on a GPU.

sorane1040d ago (Edited 1040d ago )

I could say the same about Killzone which is even worse in both graphics and gameplay.

Jovanian 1040d ago

@above

"Even tho we all know it makes no sense"

I don't see why consoles deserve special treatment and are suddenly not allowed to be compared to another piece of hardware that is used for gaming

starchild1040d ago (Edited 1040d ago )

Ah yes, the old console fanboy standby of screaming "elitism", while they turn around and act like true elitist douchebags to other console gamers. This is especially true of you Sony fanboys. Hypocrisy at its finest.

The only difference is, there really is fairly minimal difference between most of the consoles, while the PC is objectively far ahead.

Edit: sorane's right, you guys need to quit bashing Crysis all the time. If anything, Killzone fits that description better.

Metacritic scores:

Crysis = 91
Crysis Warhead = 84
Crysis 2 = 86
Crysis 3 = 76
Series average = 84.25

Killzone = 70
Killzone Liberation = 77
Killzone 2 = 91
Killzone 3 = 84
Killzone Mercenary = 78
Killzone Shadow Fall = 73
Series average = 78.83
