HWBOT Research Lab - AMD Thuban Voltage and Temperature Scaling - Part 4

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

[anvil]

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 !

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.
