Who is most affected by the vulnerabilities of Intel processors is Apple, which loses up to 40% of performance on its computers.
The passing of Steve Jobs is leading Apple to disappear from the hardware market. The company seems to contribute strongly for the services, since in terms of PC, smartphone and tablets they are dead. Lack of innovation, infinite manufacturing defects, pitiful performance, and more are weighing on the company. And if that was not enough Apple suffers greatly from performance degradation due to ZombieLoad vulnerabilities. Specifically, the performance reduction has been estimated at 40%. This is because they have disabled threads to ensure security.
Apple suffers a 40% performance drop from ZombieLoad
All Apple computers with an Intel processor from the seventh generation to the fourth generation. The XNUMXth generation and the XNUMXth generation are exempt as they mitigate the Meltdown vulnerabilities. Something that can be seen in the documentation of these vulnerabilities.
About all this Apple has said:
“Intel has disclosed vulnerabilities called Microarchitectural Data Sampling (MDS) that affect both desktop and laptop computers with Intel CPUs, including all modern Mac computers.
Although there are no known vulnerabilities affecting customers at the time of writing, customers who believe that their computer is at higher risk of attack can use the Terminal application to enable an additional instruction from the CPU and disable HyperThreading technology. that provides full protection from these security issues
This option is available for macOS Mojave, High Sierra, and Sierra and can have a significant impact on your computer's performance.
Testing conducted by Apple in May 2019 showed a reduction of up to 40 percent in performance with tests that include multi-threaded workloads and public benchmarks. Performance tests are performed using specific Mac computers. Actual results will vary by model, configuration, usage, and other factors. "
