Apple to drop Intel chips on Mac and MacBook

Intel has revealed that it won't patch certain chip families affected by the Meltdown and Spectre vulnerabilities. They include: the Bloomfield line, Clarksfield, Gulftown, Harpertown, Jasper Forest, Penryn, SoFIA 3GR, the Wolfdale line, and the Yorkfield line. Core 2 processors are no longer scheduled to receive updates, and, while some first generation Core products have microcode updates available already, others have had their update cancelled.
Intel rival AMD, meanwhile, has yet to release any microcode updates for Spectre whatsoever, relying instead on third-party protections such as the use of a return-trampoline (retpoline) aware compiler for kernel compilation.
The entire new series of Coffee Lake-H processors support dual-channel DDR4-2666 memory and the Xeon chips are also compatible with ECC memory.
Its stated reasons also include that the products lack commercial system software support.
The processors have micro-architectural characteristics that preclude a practical implementation of features mitigating Variant 2 (CVE-2017-5715).More news: Trump's lawyer discussed idea of him pardoning Flynn, Manafort
At the top of the stack, the 8th Gen Intel Core i9-8950HK processor is optimized to push the limits of performance.
The reason why Intel won't be patching the Spectre and meltdown exploits in specific Intel chips is that of three reasons which are as follows. For example, the Bloomfield processors in question are high-end first-generation models: the Intel Core Processor Extreme Edition i7-975 and i7-965, and Core i7-920, 930, 940, 950, 960 (alongside Xeon offerings). Seven families of chip architecture will now not get Spectre patches.
The out-of-band update disabled Intel's mitigation for the Spectre Variant 2 attack, which Microsoft says can cause data loss on top of unexpected reboots.
Now, financial analyst Wasmi Mohan - who works at Merrill Lynch - has added further discussion to the rumours by claiming that Apple would be able to boost productivity by making its own chips.
Roughly a week after the update was released, many machines still lack the fix for the critical CPU vulnerabilities.
