A new Microsoft Windows Update is here to patch the Meltdown related issues but it seems that installing the new Microsoft Windows Update reduced performance for some people. If you are using an older CPU based on the X99 platform then you are most likely affected by this new Windows Update.
The X99 platform is a high-end platform and users are noting that their clock speeds have reduced when comparing the performance of their CPUs before and after the new Windows update. There might be a lower overclocking margin as well but that is something that we cannot confirm at this point. What we do know is that clock speeds are indeed being reduced by the new Windows update.
One user reported that before the new Microsoft Windows update, his CPU was able to go to 4.2 GHz on all cores but after the update, the same chip only ramped up to 3.7 GHz and the single core was able to get to 4 GHz. That is a major gap in performance and I do not know if Intel knows about the issue right now.
This seems to be some kind of issue between the BIOS microcode and UEFI / OS microcode and might be patched in a few days or so and if that is the case then motherboard manufacturers will need to release a BIOS update which you will need to install. This seems to be the least of Intel’s worries right now as not only does the company have issues with previous platforms, it seems that the company does not have enough supply to cater to the current and upcoming series if CPUs.
This is going to be a major issue as people are going to want to get one of these chips and due to the low supply, prices are going to rise. This also gives room to AMD to get some market share as AMD chips are pretty well supplied right now and they are also great value for money keeping in mind the additional cores and threads that they have to offer.
Let us know what you think about the new Microsoft Windows Update and whether or not you have been affected by the issue.
