PRESSHOT? Think Athlon Heat FX!

EDEN you will do anything to try to make INTEL look good

are they cutting u a check?

sheeeshhhh

Wow, the way I see it - Athlon will be faster and cooler then Presshot!

ooh come on poppy be a pal~~~~

Time to get into the comercial airconditioning bussiness.

Nice play on words, but it does run cooler! period. Presshot is the hottest and not in a good way.

Saw a pic/video (Tbreak?) of the FX running at 39c air cool with stock HS. how can that be?

AMD has cleared up all power consumption rumors Johan @ Aceshardware...

<b>I was reading the messageboard and I noticed that some people noticed that the "opteron might consume up to 89 Watt". For reference, the TPD of a P4 3.2 GHz is 83Watt (maximum Power dissipation > 100 Watt), so 89 Watt is a lot. I like to clear that up.

First of all, if you think about it, it is very hard to believe that the Opteron (1.8/2 GHz) consumes 89 Watt. A 2.167 GHz Barton consumes typically less than 60 Watt, and at most 75 Watt. Now consider how much a 2 GHz Athlon with a lower core voltage (1.55V versus 1.65V) on a SOI process might consume. That would be a lot less than 60 Watt (Power is proportional to voltage squared). It is hard to believe that the integrated northbridge and 512 KB extra cache would increase the power dissipation so much.

So where does the 89 Watt number come from? Well, I asked AMD. AMD has made - IMHO - a very good move: for all "Hammer cores", motherboard/heatsink manufactures have to design for a "worst-case" CPU that dissipates up to 89 Watt.There were too many Athlon boards which could not be upgraded, because the power circuitry was not designed for faster Athlons. For each faster Athlon, all heatsinks had to be tested again before AMD could recommend them.

For the new "Hammer Family" (Opteron and upcoming Athlon 64), AMD wants all boards & heatsinks to be capable of supporting even the fastest CPUs (well, if the number of pins stays the same), so that people would be tempted to upgrade their CPU more quickly.It is very questionable if the Hammer cores will ever need that kind of power (in the current process and package). The 89Watt number gives AMD a lot of headroom.

We have been testing a 2 GHz (and even faster ) Opteron, and these CPUs run quite a bit cooler than a typical Athlon. Even with the very good (Cu) Ajigo MF035-032I heatsink, I am not capable of keeping the Athlon 3200+ below 55°C when running rendering benchmarks. Only with a very fast 6800 rpm "jetfighter fan" we can make the Athlon 3200+ run cooler.

The Opteron 2 GHz runs at 35-38°C when running idle, and even after a lot of rendering, it still runs at 45°C. Granted, both CPUs are not using the same heatsink, but the fan of the Opteron 2 GHz runs quite a bit slower. So while we don't know the exact power dissipation right now, I can safely say that even maximum dissipation is nowhere near 89 Watt. More on the 23rd... </b>

I know about that. Try imagining a 2.8GHZ's thermal dissipation first!

That's my problem, projected heat. We know by now that temps will not affect our room, it's the heat dissipated. You could have an 80W P4 that runs at 40ºC, but that won't make a 50ºC Athlon at 80W make your room hotter. At least from what I read here.

It's great to see that the 2GHZ runs at about 45ºC LOAD, though it doesn't say much for the future versions at 2.8GHZ+. P4s at 2GHZ ran much much cooler.

Hopefully the next SOI batch will improve, as I won't put any faith into 0.09m from AMD and great results before early 2005.

The more I read this forum the more I don't care about this crap. Is anyone's ego satisfied yet? Seriously.

"Don't question it!!!" - Err

They also ran much slower.

You have to judge the efficiency of the processor by work output vs CPU cost, or by work output vs power consumption. You're falling into the trap of comparing by clockspeeds again...

Also, check back a few months on Ace's--they actually conducted some tests to get an approximate measure of the Opteron's power consumption under load, by utilizing some advanced monitoring features of the Service Processor in an Khepri 1u. IIRC, they found processor wattage under load to be high 50's or low 60's.

Why would this be bad?

This is actually a nice design. If your post was to bash the Prescott cooling, why don't we poke fun at the "finally true meaning" of Jet-Engine cooling, for the K7, the Jet 7 HSF, hmm?

Companies need to research and find ways to cool the CPUs, that's a fact. I hope that we never resort to water-cooling. Intel might just have to push the innovation market again and push a new standard minimum PSU power, so their CPUs and future AMD CPUs survive the 100+ power demand with the other high-power demanding hardware like the Graphic Cards.
I am saying Intel needs to push this, because as always, they are known to really do make the market move. Their visionary IDF conventions and press statements drive the market. That's not to stop AMD from doing so, but that's another thread altogether.

Captain Obvious says that is Obviously a good cooling solution!

A big copper core to conduct heat away, and radial fins with no fan deadspot problems!

Captain Obvious believes this design would be even better with a taller heatsink with a Heat Pipe core!

WTF is the problem ? You realize your 19" monitor puts out a lot more heat than your cpu right ? You realize also, your PSU burns about as much electricity as it converts to your components, right ? <b>But did you know a typical adult consumes 100W of energy ?</b>
(source: "Body, Physics of." Macmillan Encyclopedia of Physics. New York: Macmillan, 1996." )

So if your room heats up, may as well start by going outside yourself

As to your original statement about the Athlon FX power consumption; from all reports I read on the web, it seems to be a cool cpu. There are no hard figures (as stated, the 89W is the maximum for the entire hammer family, likely for a 2.6+ GHz model), but it shouldnt be far from 60W, so I don't see the problem really.

As for Prescott... 100W is a lot, but not problematic. the only problem I see is that 100W figure going up with clockspeeds, and then silent cooling can become a serious concern, and SFF becomes nearly impossible. For the rest its pretty much a non issue..

I'd like a link to back that up. I don't believe the brain could output 300+W without some forced cooling . Numbers I recall are 20W (or rather, 20% of total energy consumption).

Just a matter of time before they start useing coolant filled heatsinks to move that excess energy away.

Some do use coolant filled heatsinks. Some laptops and those Shuttle cases use copper pipes filled with some gases that help transfer heat a lot better than just metal.
