AMD back in gear, Centurion FX

He obviously meant "air", but you know that and just need to belittle him I guess. Nice going man.

It was an obvious typo, I did not mean to "belittle" him. The image just struck me as funny. If he is offended, I apologize.

Edit: maybe you should examine some of your own posts is this thread if you are so concerned about belittling or offending people.

Hmm, I didn't know anybody had 8350s running on air, but I haven't really spent anytime in thread on overclocking Piledriver. I didn't know there were some running on LC, but that's just because I was looking at case mods and saw some specs.

Well, frankly I don't know first hand if there are or aren't 5GHz FX-8350s that can run on air either. But - if this news is true - I bet there are somewhere because otherwise I don't think AMD would be able to do it.

AMD will have more chances of finding golden CPUs than overclockers because not everyone buying their CPUs is overclocking them. Then again, I don't think AMD is going to now try stress testing every CPU at 5GHz as part of their standard binning procedure, but they should at least be doing enough to make it apparent that they have a winner on their hands just from stock binning. An especially low VID or something.

Still, we're not talking about something that'll be one in a million, there's no way AMD could be able to make a product line off of that, no matter how niche. I'm sure there's going to be at least someone out there who has CPUs that are at least as good. At least for the time being - this kind of aggressive binning would mean AMD is going to be removing some or even all of the best units from the CPU lottery.

On the flip side, if there is a market for cherry picked overclocked FX-8350s at 4x the price and there's still a high enough chance of finding them in the wild that just opens the door for vendors to sell their own 5GHz binned units. At half the cost. Come to think of it, if there's a market for AMD to do that why aren't stores already doing it? Or is there a sales agreement that prevents this?

So first scenario makes this bad for overclockers buying FX-8350s, second scenario makes this a non-starter for AMD.. take your pick.

Re:VRMs, I wonder if moving to integrated VRMs will give CPU manufacturers more leverage in offering specialized parts that don't need specialized motherboards? Probably more likely the opposite, with integrated VRMs not offering nearly what high end motherboards can :/

If AMD have already announced this then they have been doing this for a long time already.

What makes you say that?

 

[inf64]

AMD has not announced anything yet and they haven't commented on this subject (as far as I know). So all of this might be just hot air.

I'm sure a real 5GHz fan-cooled Vishera will generate plenty of hot air too

 

[Rifter]

Im hoping this is a joke.

Otherwise WTF are they thinking with the power consumption and price point of this beast?

 

[galego]

Where do you get those "hair" coolers? Is that the opposite of a hair dryer?

Sorry was a typo, corrected.

 

[Durp]

There are already Piledriver users running FX-8350 at 5.0 GHz on air and with the stock cooler.

I don't detect sarcasm so this is just plain . Unless your room ambient is cold enough for ice to form, this isn't going to happen.

No offence, at contrary, the idiocy that I wrote did me laugh.

They don't need to do that. They can measure certain electric/thermal parameters at the lower stock 4 GHz and pre-select chips with values under those correlated to the predicted values of the parameters at 5 GHz. They only need to perform stress tests on the pre-selected CPUs and return to the ordinary line those that fail the test.

On liquid cooling I can get my 8350 to boot into Win8 at 5ghz. Of course I need crazy vcore and it isn't stable for benchies. Heat goes through the roof.

On a custom liquid cooling system, I've seen some forums where they claim stability at 5 Ghz.

On balance IDC has the best approach with his anaysis of the 8350. I set my 24/7 cap at 4.6Ghz (21 x 219). This is stable with prime 95, IBT, OCCT etc. PLUS, the heat output is manageable.

 

[guskline]

Oh this just in!

AMD shows you how it is going to cool the "stock" 5 Ghz Centurion at $795.00

There is PLENTY of air in this video. A hoot!

I don't have more info about that. However, there are people who is running above 5 GHz on air, with aftermark HS and stock fan, on rooms with 20--28 ºC of ambient tempt.

we have it on good authority that the chip-maker will soon be releasing a super-FX chip.

 

[guskline]

God love you galego! Did you follow the posts prior to the Bulldozer 8150 release? If you did, you'll pardon us for being so cynical.

 

[galego]

My first estimation is that Centurion would achieve about a 90% of the performance of the i7-3970X (under Windows) by only a 77% of the price of the Intel chip.

The AMD chip would be faster under linux.

I think you meant only 77% of the PRICE of the Intel chip.

FAIR WARNING galego. You are about to unleash the fury of the Intel I7-3900 series fans. WATCH OUT!

You forgot the part about the 220% increase in power consumption necessary to reach that 90% performance sweet spot.

 

[Sweepr]

Sounds like a last hurrah before AMD goes APU-only (client & mobile) with Kaveri.

According to Hardware.fr charts it would still be slower than the nearly 1.5 year old 3930K while costing more ($795?)... likely more power hungry and hotter too (not too mentiont less OC headroom on air/water). It might make sense if you're trying to break OC records w/ LN2 but... FX8350, i7 3770K and i7 3930K would be a much better choice for most people.

 

[mrmt]

You forgot the part about the 220% increase in power consumption necessary to reach that 90% performance sweet spot.

And heat dissipated. I doubt you can reach that clocks living in Houston without AC. It would not be unexpected from AMD, as they tend to mock their customers with things like that from time to time.

 

[guskline]

IDC did a great thread on the power draw of the 8350 as you upped the clock. I seriously doubt AMD spent much time tweeking a 8350 just to get to 5ghz on air.

No need of tweaks , historicaly AMD always managed
30% higher frequency without TDP increasing much
for all their nodes once they were mature , so they could
well bin exceptional parts that will do 25% higher frequency
with at most 40-50% higher TDP.

That's what I was trying to say in the second sentence you quoted, but that probably wasn't very clear..

How about vs i7-3930K instead?
