http://ranker.sisoftware.net/show_run.php?q=c2ffcfe988e9d4ecddeadbe8dafc8eb383a5c0a598a88efdc0f8&l=en
Seems to go up to 118W in all core turbo mode.

Will they make an Z370 version of this board?

My 1700 at 3.9 goes up to 83.9 watts in the same test for reference: http://ranker.sisoftware.net/show_run.php?q=c2ffcfe988e9d4ecddeadbefdafc8eb382a4c1a499a98ffcc1f1

Edit: Hmm they are using an older version of sisoftware sandra(2.20), what's up with that? I'm not familiar with this benchmark.

What's the news on solder versus glue?

Don't expect them to be soldered the Skylake-X 12-18 core parts aren't.

n both cases Intel’s NGPTIM could only outperform KPT-8 (an old thermal paste developed in 1974 in the USSR) paste and was less efficient than inexpensive Arctic Cooling MX-2. Highly-efficient Coollaboratory Liquid Pro compound proved to be dramatically better than Intel’s NGPTIM.
and the Soviet TIM was 1c hotter rolleyes.gif

Your CPU reads 3.9GHz , 83W seems low, did you get a golden chip that needs 1.2-1.3V? Is the test really that low power consumption on Ryzen?

I noticed a R7 1700 on Asrock Taichi @ 4GHz also uses ~86W. http://ranker.sisoftware.net/show_run.php?q=c2ffcfe988e9d4ecddecd5e0d9ff8db080a6c3a69bab8dfec3f3&l=en

Its not that costly (especially when you factor in Intel's built-in margin advantage over AMD).
What do you mean AMD is more efficient than Intel? Intel has a higher IPC then AMD.

It's also higher than ARM, but that doesn't tell us squat about power efficiency tongue.gif


Seriously though, I'm not sure about "better", but Zen does seem to be on par with Skylake in terms of power efficiency (at least with the server and desktop SKUs). Better in some workloads, worse in others.
Skylake is outdated and Kaby lake has 14nm+.

I need 1.312 for 3.9. Ryzen and GloFo 14nm LPP are pretty efficient it seems.

The highest I've seen is with the cache b/w bench(122 watts): http://ranker.sisoftware.net/show_run.php?q=c2ffcdfcdabbdae7d3e2d5ecddfb89b485a3c6a39eae88fbc6f6

An overclocked 7900x hits 308 watts in the same bench: http://ranker.sisoftware.net/show_run.php?q=c2ffcdfcdabbdae7d3e2d0e9dcfa88b585a3c6a39eae88fbc6f6&l=en

Skylake still is the architecture Kaby Lake,Coffee Lake and Cannonlake will use wink.gif

also clock per clock there is no performance gain

Coffee lake will have six cores, 200MHz increase in clock speed from 14nm++.wink.gif
