Raptor Lake is Intel's codename for the 13th and 14th generations of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficient cores. [ 3 ] [ 4 ] [ 5 ] Like Alder Lake , Raptor Lake is fabricated using Intel's Intel 7 process.
Intel promised microcode updates to resolve the vulnerability. [1] The microcode patches have been shown to significantly reduce the performance of some heavily-vectorized loads. [7] Patches to mitigate the effects of the vulnerability have also been created as part of the forthcoming version 6.5 release of the Linux kernel. [8]
In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
Intel reported that they are preparing new patches to mitigate these flaws. [24] On August 14, 2018, Intel disclosed three additional chip flaws referred to as L1 Terminal Fault (L1TF). They reported that previously released microcode updates, along with new, pre-release microcode updates can be used to mitigate these flaws. [25] [26]
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
Intel is planning to address Variant 4 by releasing a microcode patch that creates a new hardware flag named Speculative Store Bypass Disable (SSBD). [ 7 ] [ 2 ] [ 12 ] A stable microcode patch is yet to be delivered, with Intel suggesting that the patch will be ready "in the coming weeks".
An iterative refresh of Raptor Lake-S desktop processors, called the 14th generation of Intel Core, was launched on October 17, 2023. [1] [2]CPUs in bold below feature ECC memory support only when paired with a motherboard based on the W680 chipset according to each respective Intel Ark product page.
