It is unclear whether this will affect other processors
It seems that soon all Intel Core i9 processors of the last two generations will become much slower without choice on the part of users. Intel has reportedly asked motherboard manufacturers to set special Intel Default Settings as default settings.
We already know these settings in the form of the Baseline Profile, which appeared in the latest BIOS updates from various motherboard manufacturers. But now, after updating the BIOS, you need to select such a profile in the settings yourself. Intel wants motherboards to work out of the box with the appropriate settings.
Intel wants motherboard manufacturers to implement the transition by May 31st. Here it is worth understanding that if you do not update the BIOS, then no new settings and profiles will appear. And most ordinary users, of course, do not update the BIOS of their motherboards. However, those who buy a new PC or motherboard will get the Intel Default Settings profile out of the box as a base profile, which means that 13th and 14th generation Core i9 processors will run noticeably slower or much slower than usual .
The Intel Default Settings profile sets the power values for PL1 and PL2 to 125 and 188 W, respectively. For comparison, the Extreme profile, which is usually the default used by all board manufacturers, implies 253 W in both modes. 125 and 188 W — these are exactly the values that Gigabyte set for the Baseline Profile. And in this mode, the Core i9-14900K loses a third of its performance and drops to a level slightly higher than the Core i5-14600K, at least in resource-intensive applications. Interestingly, the Core i7-14700K in this case will apparently be simply noticeably faster, although it is not yet clear whether the settings will affect it too.
It is also worth understanding that Intel’s appeal to motherboard manufacturers with such a serious request means that the company has not found other options for solving the problem. And we've already seen news that the successor to the Core i9-14900K, called the Core Ultra 9 285K, will operate at just up to 5.5 GHz, which may well be due to a problem with the current Core i9.
May 15 Intel should publish some kind of official statement regarding this whole situation, perhaps some new details await us.
For now, the situation is very unpleasant both for Intel and for owners and potential buyers of Core i9, since the processors will actually be very noticeably cut down. Of course, anyone can use the same Extreme profile, but at their own risk.
