No clock drift (timer) issue with Skylake

[Massman]

Just a quick thread to show there is no RTC or clock drift issue with Skylake when changing the BCLK at runtime.

 

Test: Skylake i7 6700K with RTC enabled in Windows 10. Based on the findings described here, we would expect a difference in benchmark result from running 41x100, 40x102.5, and 42x97.6. Specifically, 42x would be approximately 3.4% faster than 41x.

 

In our test we find that:

• 40x102.5: 8.977 sec
  
• 41x100: 8.983 sec
  
• 42x97.6: 8.999 sec
  

This confirms with the hypothesis that Skylake isn't affected by clock drift.

 

The real technical reason is that the BCLK frequency is now a separate ICC and is no longer tied to the other clock frequencies.

Does this mean we can run Win 10 with Skylake for submissions?

[der8auer]

That would be the conclusion, yes

Great! Can we get an official announcement of the sort?

[Massman]

Yes

How deeply was this tested and was there already an official confirmation that all benches on skylake are allowed to be done on windows8 and windows 10? Can´t find it

Indeed, so I blocked tons of submissions because there was no official statement nor proper change to the rules. Now I have to pardon myself for their removal ? How does this make the moderator crew look?

I'm loving this epiphany
