10 reasons why you should not buy an Intel CPU or CPUs into your desktop machines
1. It is overpriced for its performance - 70% difference in cost, 20% difference in performance. You can find a lot of benchmarks out there, look at most application benchmarks because you will never be using full CPU performance in anything but heavy enough applications.
2. They have a whole bloody lot of critical vulnerabilities specific to them recently discovered, that when avoided ('fixed up') by CPU firmware and OS, drop the performance quite a lot
3. They change motherboard sockets every now and then on a whim, so further upgrade would not be easy
4. The good motherboards and chipsets for these are overpriced as well, everything else is just meek
5. They are technically inferior, manufactured at 14 nm process, while current AMD CPUs are at 12 nm and next generation coming soon would be at 7 nm
6. They drop frequencies of the whole CPU under heavy AVX vector calculational loads - https://blog.cloudflare.com/on-the-dangers-of-intels-frequency-scaling/
7. They have a stable huge userbase of those who overclock, meaning buying such CPU second hand can result in getting a 'nicely grilled' one
8. Recently, there were certain reportings that declared TDP (thermal dissipation, which stands almost equal to how hot the CPU is) for the top class desktop CPUs may actually not be real - https://www.anandtech.com/show/13591/the-intel-core-i9-9900k-at-95w-fixing-the-power-for-sff
9. If you prefer just an integrated videocard in your laptop or even desktop, the performance of integrated GPUs is totally terrible compared to AMD - look at the gaming benchmarks here, because for office productivity (except for some specific case of 3D design, modeling and some other specific jobs) GPU mostly does not matter.
10. They usually have thermal glue under the lid instead of solder (although some AMD CPUs have this flaw as well, and some Intel CPUs don't), leading to bigger operating temperatures (so more noise from your CPU and case fans)
Everything written above is just a personal opinion, you should think on it twice and don't take any things from it at the face value too willingly.
