Xbox One: Overclocked again, this time the CPU +150Mhz

[glutesontheloose]

Not sure if this has been posted already but: http://pixelenemy.com/xbox-one-150mhz-cpu-boost-takes-it-from-1-6ghz-to-1-75ghz/?fb_source=pubv1

 

 

Seems like Microsoft is trying to push everything to make that extra 100$ reasonable.

But imo I don't think its going to be much of a performance boost from 1.6 to 1.75ghz.

Overclock it to 4 GHz and put a 7970 in there and then I will be impressed.

[Kirihuna]

>1.7GHz

 

giggling to myself.

>1.7GHz

MS's such a tryhard on this one..

[onionring]

why do they over clock the thing I can t see it being such a good thing.

I mean over clocking the thing it will overheat/sound like a jet engine.(in your living room) and might cause red rings of death...

Well we don't know how much thermal head room they had before.

Are they even overclocking. I thought they underclocked from the start and know are only less underclocking the GPU and CPU if that makes any sense. So really they are still using underclocked hardware.

they have these small bumps because they don't want RROD happening all over again, because these are mass produced, you have to take in consideration that not all these chips are going to bin well, and therefore, you need to have a bump that will work across the board, it's not like an individual PC, it's much more different when it comes to mass production

The PS4's CPU goes all the way up to 2.75Ghz with turbo boost, so while 1.6Ghz to 1.75Ghz base clock doesn't seem like much, it's going to improve turbo clock speeds noticeably.

that picture in the link u sent doesnt look like an xbox one what is it?

I think it is. Its just showed the right side of the console and you could see the reflection on the left side.

We don't know the PS4 CPU clockspeed. We also don't know that it has turbo boost. We just know that the FCC document said 'maximum speed of 2.75GHz'.

We know that from the FCC document, maximum speed of 2.75Ghz can't be anything but the turbo clock for the CPU, because the GPU can't go that high.

phones are 2.3Ghz now! hahaha I smell overheating issues already.x

[Kuzma]

Well actually what everyone's failing to see is how that 150mhz will scale over the number of cores due to the fact it will have multi-core optimisation so it'll be more like 6-900mhz OC in terms of performance gains.

It doesn't really work like that.

I'm describing it in a perfect world in a perfect world it would indeed work like that but seriously clock speed is an exponential growth and it seems people don't really see it like that >_<

I see what you did there

But, it's not really. Even in a perfect world where everything could utilize all cores 100% without any drawback whatsoever, a 100% overclock would still not equal a 100% increase in performance, or a 400% increase in performance on a quad core.

Why? Because clock frequency is not the only thing that determines the performance of a CPU.

so you're telling me for a task that is 100% cpu bound and doesn't rely on any external factors a 100% overclock would not see a performance increase of the same magnitude?

Nope it would not. You might see that to a certain degree, but sooner or later you will see a diminishing return from just increasing the clock speed, because you start running into bottlenecks like path prediction, cache, the latency between different components (even different components inside the CPU) doesn't go down just because you overclock and so on.

CPUs are much more complex than that.

 

Also, Microsoft have implemented some new throttling thing into the Xbone, so I suspect that it was prone to overheating even without this frequency bump.

 

It's not really an exponential growth either by the way. In the absolute best case scenario, an increase from 1GHz to 1.1GHz would yield exactly the same performance increase as going from 2GHz to 2.1GHz, so frequency is a linear growth and not exponential. Or if we want to be even more correct, it's like a reverse exponential growth because the performance benefit becomes smaller and smaller for each MHz after a certain point.

The mathematical term for that is Logarithmic or Asymptotic or both. It's the same reason why SLI doesn't scale well either (adding a second GPU doesn't result in 2x performance or 100% gain).

[Nicktrance]

Wow they're really worried this will fail, aren't they? I doubt a few MegaHurts will make any difference other than more beautiful numbers with no real benefit...
