The high temperature of the Ryzen 7000, voltage problem or BIOS?
As we anticipated weeks ago, the Ryzen 7000 had all the ballots to be really hot processors. The data from a few days ago was just a preview of what is to come, and now new leaks somehow reveal a path perpendicular to the one taken with the temperature problem. Due to this, a new processor has made an appearance revealing its frequencies, consumption and of course, its temperatures, which raise doubts. Are we facing a new issue of BIOS Y voltage at an AMD release with these Ryzen 7000?
The first data of Ryzen 9 7950X left a bad taste in the mouth in general, since with “only” 230 watts temperatures were above 90ºC without any difficulty. He followed the same path Ryzen 5 7600X that with a PPT of 130 watts we also saw it at very high temperature levels. At that time there was no answer or possible solution to this high data, but today we may have a little more light on this matter.
AIDA64 shows Ryzen 7000 voltage and temperature issue
Ryzen 7000 stock VS manual voltage in same CLK
Ryzen 7000 is hot, but isn’t hot.
In stock/heavy load, not only that CPU tend to down CLK too much, but also take too high V.

When you go to the limit and push to reduce an unfavorable GAP, what happens is that everything gets complicated. We do not know exactly which CPU we are going to talk about next, because it has not been revealed, but we can say that there are two different configurations, one stock and one with manual voltage.
What you see in the left column is the stock version of the processor, where you can see a 5.05GHz frequency sustained, while consumption is established on the 122 watts on average The problem is that temperatures shoot up to 93.1ºC when their nuclei are stressed with UPF. Logically, that consumption and that temperature show a very serious problem that recalls past times in other architectures.
Luckily, it seems that there is a solution, at least partial, since with a manual adjustment of the voltage, almost half of the consumption is passed (67.92 watts) and a much cooler temperature of 56.5ºC on average
Is it a voltage or BIOS issue?
Since Ryzen came out as a general architecture on the market, what we have seen over the generations is that AMD always points the stock voltage for its processors a little higher than Intel does. There has been a lot of talk about it and in the end the conclusions that have been drawn over the years is that AMD tries alleviate the deficit of ASICs and chips giving a few more points of voltage to maintain stability and thus achieve more capable processors per wafer, and may be more profitable.
The problem is that the Ryzen 7000, apart from this temperature problem, have already faced a first delay with the BIOS from the 15th of this month to the 27th, where other factors have joined the meeting. What we do not know and it is possible to intuit, is that the manufacturers and AMD have not achieved a good fit between the power phases, the voltage controllers and the final voltage on the chips.
It is not normal for consumption to be reduced by almost half, as well as the temperature, in a stock processor after a manual adjustment of the voltage. we would be talking about between 2.5 tenths to 3.5 tenths more fresh out of the box for the same frequency. Also keep in mind that this unit is more than likely be an IS and that you might face these issues that seem more like BIOS settings than anything else.
very much in the style of Intel SA series and above all, when an XMP profile is applied to the memories, where the voltage shoots up in more than two tenths of an average. Therefore, “don’t let the cunic panda”, it is more than likely that this will be corrected at launch, although they will not be fresh as such, according to everything we are seeing. The positive part is that with only 65 watts seems to be totally stable at 5GHz (at least on paper, only FPU is stressed and for a very short period), so if we talk about CPU versions for laptops, this opens a more than important closure in efficiency to compete with Intel.
