Interesting article.

 

Any expectation on the clocks under Liquid Helium ?

I noticed that the temps were dropping by ~10°C at 5.8G 06, so it seems that the dragon f1 isn't capable of holding the load. The CPU still scales with temperature a lot, so I'd say at least 200 to 300MHz more on the same chip when going LHe. Leaky chips would be even better ...

I read this morning that Pt1t reached 6.5 on the 1090T he tested.

I don't know if this chip is simply a Golden Sample or not, but this promises a lot for the future.

Well ... no. It's one thing to get a CPU-Z validation, but something totally different from having the six cores completely stable through a 3D benchmark. This chip can only do 5.5GHz Wprime 1024M iirc

Yes you're right, didn't pay attention to that

Fine!

 

amd is take advantage on your processors but intel has the leader

nice sharing !!

I got similar result with my 1055T/1090T on air

Thanks !

Great article Massman!It has a lot of info very helpfull.

Thanks!

Excellent analyze

Great job!

Thanks for the link. It's correct. I had best experience with Phenoms. It was interesting, they scaling very well also with aircoolers. I remember, 20C ambient vs 5C ambient, it was extra 100-150MHz in Cinebenchr11.5. And for Superpi 200MHz more.
