Doesn't even matter if that 5Ghz on air figure is stable or not. It still bodes well for the architecture in general. If it's not 100% stable at 5Ghz, means it's stable at 4.7Ghz which would be pretty good.

I would be happy if we could hit 4.2Ghz on all cores on air.
With their pricing, any kind of overclocking, especially 4.2 Ghz, will be extremely competitive, that is for sure. However, in my experience with overclocking, the delta that you might see between a maximum "suicide screenshot" OC on 1 core and fully stable on 8 cores is going to be far greater than 300 Mhz (the thermal delta for 1 core idle vs. 8 core loaded is huge), so I think 4.7 Ghz could be optimistic. But, we will find out soon :).

8 cores loaded and overclocked/overvolted will lead to drastic wattage increases... like any 6-8 core intel chip, pushing these to the max will require the cooling capacity of water.

Hmm so 1700x hits 1547 and 1800x hits 1601. Not a huge difference. Might buy 1700x instead.
~3.5% better as a result of higher efficiency, which should translate into lower temperatures, which should then translate into higher clocks.

Since XFR was undoubtedly in use, that's the only conclusion one can make.

Hey dude, seems like you have a reviewing sample(You said I'll review on bla bla bla conditions). Is OC headroom as low as the OrangeKrush states?

I do not have a review sample, however I fully expect overclocking to be very limited by thermals.

It's a ~192mm^2 die that needs to dissipate 125~140W to boost all 8 cores to 4Ghz. Six cores will only dissipate ~20W less. So you're talking about 4.2GHz only. Then a quad core should be about ~25W less, which should allow 4.5GHz.

With the 140W X-Series heatsink, and a 4GHz 8-core, you're looking at 80~90C.. which may actually be safe MAX temps, unlike with older AMD CPUs using SOI processes.

From the architecture, it seems like 4.7GHz should be safely doable if you can keep it cool. AMD went to great lengths to reuse as much of their existing technology as possible - and we know how that clocks already.
