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.
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 when paired with a motherboard based on the W680 chipset according to each respective Intel Ark product page.
Supervisor Mode Access Prevention (SMAP) is a feature of some CPU implementations such as the Intel Broadwell microarchitecture that allows supervisor mode programs to optionally set user-space memory mappings so that access to those mappings from supervisor mode will cause a trap.
In September 2023, Intel CEO Pat Gelsinger showcased a 20A wafer at Intel's Innovation event containing Arrow Lake test dies, reiterating that Arrow Lake products were on schedule. [7] On December 14, 2023, Meteor Lake launched in 9 W and 15 W form factors for ultra thin notebooks.

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]
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 distributes microcode updates as a 2,048 (2 kilobyte) binary blob. [1] The update contains information about which processors it is designed for, so that this can be checked against the result of the CPUID instruction. [1] The structure is a 48-byte header, followed by 2,000 bytes intended to be read directly by the processor to be ...
