Apple will Replace Intel Chips with its Own in Macs from 2020

Haifa team sires Intel's 'best processor ever' for laptops

Processors fabbed by Intel over the last decade are all vulnerable to one of the Spectre vulnerabilities which were revealed, even after the patches and microcode updates which have been released to mitigate the flaw.

Bloomfield, Bloomfield Xeon, Clarksfield, Gulftown, Harpertown Xeon C0, Harpertown Xeon E0, Jasper Forest, Penryn/QC, SoFIA 3GR, Wolfdale C0, Wolfdale M0, Wolfdale E0, Wolfdale R0, Wolfdale Xeon C0, Wolfdale Xeon E0, Yorkfield, and Yorkfield Xeon.

Intel says it stopped developing the Spectre variant 2 mitigations for at least one of three main reasons, including that it was impractical, the CPU was not widely supported, or that customers indicated the CPUs are running on closed systems.

The new processors also have the Intel 300 Series Chipset, which includes Gigabit Wi-Fi.

The company has been releasing microcode updates for the flaws at staggered intervals over the past month.

In March, Intel said that it was developing microcode fixes for processors as old as the 45nm Core 2 chips (built on the Penryn architecture) and the first-generation Core processors (built using the Westmere and Nehalem architectures).

The reasons Intel gave for stopping these updates vary, from the possibility that patching Variant 2 of Spectre is just too hard based on the design of the chip in question, to limited availability of software support and the fact that some of the affected chips are powering "closed systems" - they're not connected to anything that could allow hackers to exploit them, so the risk is so small that administrators can avoid the fuss of implementing such a tricky update.

There being limited commercially available system software support. Intel's first ever Core i9 laptop processor was just unveiled, and with the company positioning it toward content creators, it too should help push the envelope all the more.

The new range is i9-8950HK processor that comes with six cores and 12 threads. Incidentally, Apple has been installing Intel chips in its computers since the year 2005.

Intel and AMD may need to revisit their microcode fixes for Meltdown and Spectre.

The first thing to note here is that the processors in question are niche, older models, but this is still a potential fly in the ointment for some folks who are still using the silicon in question.

The performance impact of Meltdown patches makes it essential to move systems to Linux 4.14.

The company has rolled out microcode updates to fix the Spectre v2 vulnerability for many of its processors going back to the second generation Core (Sandy Bridge).

Intel has warned that it nearly certainly won't be able to provide a fix for the second variant of the Spectre flaw for all but the latest of its desktop, laptop and server CPUs.
