[PConline News] Some of the most serious vulnerabilities in the history of X86 were unveiled recently. These two vulnerabilities are called Meltdown and Spectre. The former mainly affects Intel X86 processors, and many generations of Core processors since the 45nm process. Although the risk level has not been melted down so high, but the effect is even wider, ARM, AMD and Intel processors may all be tricked. After the incident, Intel was criticized. However, they are still OK in terms of bug fixes. Jointly with Microsoft, Google, and other vendors to issue fixes, various system patches have been pushed out. They just need to fix the bug and also need the BIOS. upgrade. Recently Asustek, Gigabyte, MSI, and ASRock have launched new BIOS versions to fix bugs in their Intel motherboards, but at the cost of reduced performance. Intel's official test 8th generation processor can reduce performance by 10%. It can be said that toothpaste is a night. Squeezed back before liberation. Intel Core i7-8700K electricity supplier price reading... Melting and ghosting are related to the architectural design of modern processors, but Intel has stated that this is not a problem of processor design flaws, but that the branch prediction function may be used accidentally. In order to fix this loophole, it needs to be repaired. Operating system upgrade patches, processors also have to upgrade the microcode, the former has been implemented by Microsoft, Apple, Google and other companies, Intel has also gradually released processor microcode upgrades, handed over to motherboard manufacturers to upgrade the BIOS. In a wave of upgrades, MSI is the fastest in action. Last week it released a BIOS update for the Z370 series motherboards. ASUS also released BIOS upgrades for its 100, 200, and 300 series motherboards. GIGABYTE has done a better job in this area. The official website has directly launched a special page that focuses on the motherboard models that need to update the BIOS and informs users of the relevant issues. Details can be found on the GIGABYTE website. On these two days, ASRock began to push BIOS upgrades, mainly for Skylake, Kaby Lake, Coffee Lake and X299 series. At this point, the four major motherboard manufacturers have introduced BIOS to solve the vulnerability of the X86 processor, mainly for the Intel platform. Although it is a good thing to fix the loopholes, the impact of this loophole is a bit complicated. We have explained before that, to fix this loophole, we need to change the CPU's kernel list, which will cause performance degradation. As for the impact of performance in the end, Intel officials also did a test not long ago, comparing the 6th to 8th generation Core processors, the specific results are as follows: Intel has always emphasized that the impact on performance is not significant, and the actual measurement is not too obvious, but the Core i7-8700K has dropped from 0-12% in the various tests of Windows 10, and the average performance is about 5%. Taking into account Intel's generations of processors in the IPC architecture performance improvement is not large, even if it is reduced by 5%, it is enough to return the processor performance to the level of the previous two generations - of course, the performance of the previous two generations of processors is also Affected, Skylake, Kaby Lake part of the test decline even larger than the 8th generation processor.
