AHAHAHAHAHAHAHA...

thats only good if ur gonna keep the cpu @ STOCK! :thumbsup:
Not sure if serious... The rumored cpus will run STOCK at 4.8/5Ghz. I think that the linked HSF will have no problem cooling these CPUs. Bigger problem will be cooling the VRMs.

If 220W is such a big problem to cool,then why bother about being interested in water cooling,unless you are more worried about fancy coloured tubes and liquids,and not about actual usage??

People were water cooling overclocked overclocked GTX480 Tri-SLI setups(250W TDP each card), with overclocked socket 1366 Core i7 setups years ago so if its a problem cooling a 220W TDP CPU,whether its at stock or overclock,it seems a pretty crap setup,or you should pay someone to do it for you.

It seems pointless then to invest in custom loop for a CPU then. You might as well not bother with anything above a K series Core i5 and then use the stock air cooler,a few efficient GTX660/HD7850 cards and stop dicking around with a custom loop then or even a aftermarket cooler,if it is so much hassle.

Moreover,decent air coolers and AIO water cooling units can already handle TDPs of 200W+ anyway,otherwise all those socket 1366 Core i7 CPUs and overclocked FX8000 series CPUs would never have been able to go past stock,let alone P4 CPUs,etc.

You're way off there. My temps are in the low 60C range with all cores loaded.

no im asking you if your temps were at those ranges would you honestly be happy? because cpu cooling and gpu cooling have different target areas.

i dont think u guys are really aware of how much 220W is.
You guys have been spoiled backwards forwards silly since Sandy that i honestly think you guys are forgetting how much 220W is.

220W is about as much heat as a Q6600 displaced overclocked at 3.6ghz.
Keep note... im saying 3.6ghz @ roughly 1.45vcore.. because thats about where i remember it being when i did alot of thermal tests.

Now think back really hard on what type of heat sinks we used when we were trying to keep that Q6600 in check.

Because 220W means this chip @ STOCK is putting close to the same amount of heat as that Q6600 @ 3.6ghz.


Also u guys have heard me say this many times lately.
Today's hotzone in watercooling is no longer at the CPU.
Its the GPU sector now where water really shows its merit.
Its more benifical to watercool GPU's more so then CPU's now.
Ive seen benchmarks and reports of Quad - Titans under waterblocks not breaking 45C under 100% load bitcoining.

Oh my god, a Q6600 at 3.6GHZ? Tell me more good sir! I'm sure that chip fried itself to a crisp, right? Or did it continue to function perfectly fine afterwards?...

Lol well yes, lots of people watercool their GPU's, but CPU WC'ing is WAY more popular. Uhhh why was that poor bastard bitcoin mining with Titans... What a waste Clearly you're the one who doesn't understand.

220W is definitely watercooling worthy. Water starts outperforming air reasonably well around 150W and will take you all the way up to about 300W on today's custom blocks. I haven't seen anything beyond that on water, typically once you get above 250W you switch to phase cooling of liquid nitrogen. 220W is a lot in such a small space, its hotter than a nuclear reactor per cm squared, its a lot of energy to dissipate and will take 2-3 120mm fans on some reasonable radiators.

You never really "need" phase or LN2. Water keeps temperatures close to ambient, Phase keeps temperatures close to 0/sub-zero, and LN2 keeps temperatures close to absolute zero (to be generous). Water doesn't have a "capacity", it simply has a certain limit as far as how cold it can get (ambient). This only matters with high voltages which run the risk of frying the chip if the temperature isn't low enough. You could cool a 6gHz SB chip with water, but the issue is that with the voltages required to get to 6gHz, the amount of leakage has to be countered with sub-zero cooling.

well, as absurd as a 220W CPU may sound at first, 200, 300W VGAs are a common thing nowadays... so yes... it may well have some appeal,

it's funny, back in the day the FX line was meant to be something special, like the FX-51, it was faster, required a special MB... this new CPU could be kind of the same I guess,

still, it will be beaten by 84-130w TDP Intel CPUs.

And what is the max voltage and max temperature for that TDP to be valid? Since you are referencing AMD specs, please provide your answer in the form of AMD specs.

A spec TDP without the accompanying spec max allowed operating temperature is a TDP value that is completely lacking definition. Might as well say the TDP is "unicorns and beer" at that point, it makes just as much sense.

At any rate, looking forward to the links to the specs for my FX-8350, thanks.

Why would that info be disclosed to you? Are you a heatsink manufacturer or a final user?

Now seriously, you snipped the 97% of my post without any comment. I am curious: what is your reaction to the "100W delta" myth vanishing in the same review site you cited often in the past?

An advice: don't take their new 75W delta as final, there is still room for improvement in their methodology/measurements...

It's all dependent on pricing. If it's above $300 I can't see how it's going to be worth it. If it is priced $220 then suddenly the 4570K might look overpriced. I doubt AMD can get so many good 5 GHz dies at that cost though.

Richland looks to have made some big power improvements and obviously that will be the same for the FX. It's just possible that we'll be pleasantly surprised.

Maybe FX Centurion will be bundled with one of those

Yeah why is everyone throwing a hissy fit over that number, all we know right now is that there's speculation of a 4.5 ~ 5 GHz FX model being launched by AMD, if early richland numbers are any indication then such high clock speeds could well be achieved within the 200W TDP power envelope not to mention the magic of RCM is still gonna be there

A $60 Noctua bought at the same time as my Q6600 has been doing the job for me quite well for the past few years.

And air cooling improved quite a bit since Q6600' days. A Phanteks/similar or any closed loop will get the task done without a sweat.

Your $400 worth of cooling needed claim for this SKU is overkill, just get it already.

No, I wouldn't be happy with 65C idle. But I have no reason whatsoever to believe that this chip would idle anywhere near that temp. In all honesty, I doubt that a 5GHz Vishera would take much more power than what I run now.

I guess I don't get your point... that this chip will put out as much heat as a 3.6GHz Q6600 at stock. That's a lot, no doubt. But it is a managable number, and depending on what your goals are regarding overclocking, you can probably happily squeeze some more out of it.

I get that this type of chip has drawbacks and certianly wouldn't be for everyone. No one has to buy it if they do not want to. There are plenty of reasonable alternatives. But if the price is right, this would be an interesting part to have in my case.

Kind of ironic, considering you ignore parts of posts that ask for your system specs.

Intel tells me what the max operating temp is for my 3770k.

And AMD used to tell us the max temps for their chips, only they don't now...their lack of details coincides precisely with the timing of them having issues selling chips that conform to their own TDP spec.

If you know what makes semiconductors consume power then you would know why the TJmax value matters when creating a TDP spec in the first place.

If you are just a troll then none of this will sink in and you'll just keep spinning words like you usually do

@ sushiwarrior

Just LOL man, you made my evening. That was awesome post

Also from XS Stilt (who knows about unreleased products more than 99.99999% of people ) :
The Stilt said:
Had a better look at the Gigabyte sheet.

It says "AMD next generation FX".
Vishera is no next gen, it is almost two years old already

I assume Gigabyte refers to "TJ", which still should pop into AM3r2.

The sheet is for Rev 3.0 990FXA-UD7 which has some changes to the VRM.
Yet it appears to be a multiplied analog VRM.

We all know how accurate Intel official temps and TDPs can be

And AMD used to tell us the max temps for their chips, only they don't now...their lack of details coincides precisely with the timing of them having issues selling chips that conform to their own TDP spec.

Conspiracy theory at its best.

If you know what makes semiconductors consume power then you would know why the TJmax value matters when creating a TDP spec in the first place.

I assume you would know that TJmax is rather irrelevant, because the main factors are the safety margins and the set of real applications considered. There is no a universal formula such as F=ma for computing TDPs.

If you are just a troll then none of this will sink in and you'll just keep spinning words like you usually do

Instead posting this kind of stuff, it would be much more interesting if you did not avoid by second time the question I did to you regarding the 100W delta claim.

The claim is now debunked in the same review site that you liked to cite to us in FX vs i7 comparisons. Weird that you have no comment, but don't worry I will not insist more.

Also, galego IDC posted HIS idle and MAX power usages for HIS 3770k and 8350. I also posted in another thread my power usages for my 3770k AND my 8350. Both of us fully disclosed all of our specs. And you? Hiding behind cut and paste articles taken out of context. Shameful.

Seriously, do you even OWN a PC?

Hmm, really makes me wonder if AMD revved Vishera FX using Richland modules. Most of the design work will be paid for by Richland, so maybe AMD can really hit 5 GHz more easily and have a 'Halo" product. With a supposed new focus on gaming, AMD could be looking to beef up it's mainline APUs and FX series for those who care about bragging rights and don't care about their power bill. Those who go high-end air/LC cooling and are more likely to polish their CPUs flat and so on; just to post high clocks.
