As opposed to what? Samsung, Intel, AMD and NVIDIA and others are also “rolling their own silicon”. If a vulnerability like that was found in intel it would be much more problematic.
This particular class of vulnerabilities, where modern processors try to predict what operations might come next and perform them before they’re actually needed, has been found in basically all modern CPUs/GPUs. Spectre/Meldown, Downfall, Retbleed, etc., are all a class of hardware vulnerabilities that can leak crypographic secrets. Patching them generally slows down performance considerably, because the actual hardware vulnerability can’t be fixed directly.
It’s not even the first one for the Apple M-series chips. PACMAN was a vulnerability in M1 chips.
Researchers will almost certainly continue to find these, in all major vendors’ CPUs.
The patch for meltdown results in a performance hit of between 2% and 20%. It’s hard to pin down an exact number because it varies both by CPU and use case.

Also the article states it is found in intels chips too. So not really any better if they had stayed on that pathway either
I’ve just finished reading the article, it does not say this. It says Intel also has a DMP but that only Apple’s version has the vulnerability.

How much slower is s CPU without this functionality built in?
