Temperatures, consumption, overclocking
The consumption of both models is at a very nice, low, level, as can be expected from their 65 W TPD limit. There is not much to say here, except that with Zen 2 AMD managed to overtake Intel in terms of energy efficiency.
However, the temperature situation is much more interesting. It seems that the use of a very compact CCX at the end of the processor leads to a noticeable increase in temperature in the Ryzen 3 3300X compared to the Ryzen 3 3100, which is not helped by the 10 W higher consumption. We are curious about the location of the active cores at 3100, whether they are opposite the ends of the chiplet to improve the temperature behaviour. The temperatures of the 3300X are not much different from those of the 3600X, but the latter has to cool more 2 cores.
As for the overclocking, both processors had no problem reaching 4.35 GHz at 1.3 V set in the BIOS with an average LLC. However, the problem turned out to be the cooling, and even with the Aerocool Verkho 4 Dark, which, although not the most efficient cooler in the world, is still much better than the box Wraith Stealth, the temperatures during testing with Prime95 reached the 90oC for 3100 and even a few degrees above that for 3300X. And while for the cheaper model this is effectively a relatively adequate 12% overclock, for the 3300X it is largely pointless to even bother. Still these are the highest clocks I’ve ever reached with a Zen architecture based processor.
