US regains supercomputer crown from Chinese, for now

Re: Depertment of Energy

It would be around 2 years I would say, depending on the growth / collapse of crypto during that time. Not bad though.

Monday: Intel touts 28-core desktop CPU. Tuesday: AMD turns Threadripper up to 32

Should AMD have waiting for 7nm?

I am loving the specs of this chip but I'm a little worried that firstly, do I have any programs that will get close to using all those cores and secondly, what will they clock at (once thermal equilibrium is reached) if they are all at 100% load?

Also, if they are not coming out until Q3 this means 7nm versions will not be out anytime soon. Given 7nm Epyc is almost ready to sample I would have estimated that 7nm Threadripper could have been released Q1 2019 at a push but I can't see them coming out until Q3 2019 now with these 12nm being so late to the party, bearing in mind Q3 release could mean they are still agonist 4 months away from hitting the shelves.

Personally I would have preferred to wait a little while longer and got much cooler, much higher clocked 7nm chip version. But I guess if 7nm wouldn't be ready until Q2 / Q3 regardless then the 12nm stop gap is a good move but if this chip has delayed 7nm TR by 6+ months then I would say that was the wrong move by AMD.

This is another 10GHz Pentium 4!

I find it virtually impossible to believe that Intel will be able to make a 28 core CPU run at 5GHz on all cores within 6 months, they can't even do that with 6 cores today. And if it was being cooled by liquid nitrogen this would be exceptionally misleading. I see only 4 explanations for this announcement:

1) It is a misunderstanding or vapourware, maybe he meant by the end of the decade which I still wouldn't believe.

2) They use a totally different type of core which isn't very complex but can clock quite high, kind of like Larrabee.

3) The TDP is like 1000 Watts and you need specialist high flow water cooling system to run it which comes pre-bonded direct to the die.

4) Intel has been sandbagging us that 10nm wasn't working properly and it's actually a magical node they defies the known laws of thermodynamics.

My money is on this being vapourware and is just Intel trying to get people's attention in the hope if they are waiting for this to come out then they are not buying AMD CPUs.
