We talked about it briefly about a week and a half ago, and that’s when AMD itself admitted that the data presented in its presentation did not refer to the TDP of the processors Ryzen 7000but to PPP, then the alarms went off and now somehow they are confirmed. And they do it thanks to ASRock, since the company has shown the first data of one of the most anticipated motherboards, the X670E Taichiwho understands nothing less than 26 phase SPS Dr.MOS.
Yes, it’s not a joke, far from it. ASRock will have in its possession a motherboard that will be top of the range and out of its general characteristics or performance, without a doubt it is striking that with so many VRMs the question arises. Does 170 watts in PPT really need such a digital media power display? It is that there is perhaps more than all said about the real consumption that these CPUs will have.
AMD PPT, a double-edged sword for the Ryzen 7000 that touches the VRM
Being the top of the ASRock range, it is quite normal that we have an incredible number of phases, as well as the two EPS12V connectors. The problem is that the limitation imposed by AMD in this regard for the Packet Power Tracking It is higher than in the Ryzen 5000 and when disabled or directly set to a much higher margin, for example 400 watts, then the actual consumption of said CPUs was perfectly visible.
If all goes according to plan and AMD seems to indicate so with its declarations, the Ryzen 7000 will remain at these 170 watts as standard in the vast majority of user PCs, but for those who want to squeeze all the juice from their processor. to look for, these are really worrying consumptions. To cite an example. a Ryzen 9 5950X with 16 cores consumed almost all of the PPT allowed by AMD, 142 watts. Once this limitation was removed, consumption was on average higher than the 220 watts without too much effort, letting the thermal limit be the limiting factor in most cases.
Will the AMD Zen 4 be more “greedy” and hot?
Everything makes you think so. We’ve seen Lisa Su’s new IHS before and if we’re right, it’s going to cause temperature issues due to its greater thickness and the layout of the cores on the PCB. Moreover, the increase of 28 watts in standard will already mean that the algorithm PBO have to work harder to achieve the desired efficiency.
If a 5950X without PPT limitation were in the numbers mentioned, the supposed Ryzen 9 7950X might be around numbers a bit higher than these, where we assume they would be on the 250 or 260 watts. Those are already numbers that can’t be cooled even with high-end custom liquid cooling with decent temperatures because we’d be talking about being perfectly on the 80ºC continuousat least if there are no changes in AMD’s efficiency technologies.
For this reason, ASRock X670E Taichi needs these EPS12V connectors and so many power phase, not only for the aforementioned consumption, but also in case the user wants to play with more advanced cooling to overclock and push these Ryzen 7000s to the limits.
