Following Intel’s decision to remove SGX compatibility from Alderlink’s 12th generation processors, the company’s latest chips can no longer play 4K Blu-ray Discs.
According to Digital Trends, as announced by Bleeping Computer, Intel’s updated datasheets now show SGX as obsolete technology; As a result, people who have equipped their PCs with the latest generation of Intel processors will not be able to play Blu-ray movies on their system in 4K resolution.
In addition to eliminating SGX support for Alderlick series chips, Intel has also eliminated the ability to play Blu-ray Discs on its 11th generation processors. Bleeping Computer points out that the inability to play crystal clear content is related to disks that require digital rights management (DRM) and use SGX to provide better performance. It is worth noting that since 2016, Intel has supported Blu-ray Discs protected by the Skyline series chips.
Intel describes SGX as a technology that helps protect against many known and active threats by incorporating an additional layer of protection; But some researchers have discovered various security flaws in SGX that have led to its misuse. Bleeping Computer cites several examples of these abuses; Including the Prime + Probe attack in 2017 and the load amount injection (LVI) and the attack that targets the CPU cache.
In recent years, the popularity of Blu-ray Discs has declined; Because digital storage technology is still evolving. For example, the introduction of digital models of game consoles and the continued success of services such as Xbox Game Pass demonstrate the rich potential of digital content. In addition, the provision of online streaming services for thousands of 4K movies at a monthly fee has reduced the number of people interested in physical crystal discs.
Blu-ray drives are no longer a priority compared to the importance that users place on other components, such as ports equipped with the most serious USB standards. Of course, Blu-ray Discs also have advantages over streaming content. Users do not need an internet connection to play content on these discs, and playing content on Blu-ray discs will not be delayed.
It is worth noting that some movies are removed from online content streaming services when their release time expires; While the physical disk will be constantly available to the user. That said, people who plan to use Blu-ray Discs on their PC should use one of the Intel 7,000, 8,000, 9,000, or 10,000 processors. The Skyline 6000 series chips support SGX; But users without HDCP 2.2 are likely to have HDMI 2.0 compatibility issues.
Intel has recently fixed DRM issues; A problem that caused unexpected computer games to run on systems equipped with Alderlick processors.
