Downfall, known as Gather Data Sampling (GDS) by Intel, [1] is a computer security vulnerability found in 6th through 11th generations of consumer and 1st through 4th generations of Xeon Intel x86-64 microprocessors. [2]
In March 2016, Intel announced in a Form 10-K report that it deprecated the tick–tock cycle in favor of a three-step process–architecture–optimization model, under which three generations of processors are produced under a single manufacturing process, with the third generation out of three focusing on optimization. [4]
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 ...
A microcode update fixing a bug with the eTVB algorithm was published the previous month, but this was confirmed by Intel to not be the root cause of the problem, although it may have been a contributing factor. [43] Intel confirmed that there is no fix to the issue if it already affects a CPU, and any damage to the CPU is permanent.
Intel Xeon is a distinct product line from the similarly named Intel Xeon Phi. The first-generation Xeon Phi is a completely different type of device more comparable to a graphics card; it is designed for a PCI Express slot and is meant to be used as a multi-core coprocessor, like the Nvidia Tesla. In the second generation, Xeon Phi evolved ...
During Intel's Vision event in April 2024, new branding for Xeon processors was unveiled. [11] The Xeon Scalable branding that was introduced in 2017 would be retired in favor of a simplified "Xeon 6" brand for 6th generation Xeon processors. [12] This change brings greater emphasis on processor generation numbers. [13]
The following is a list of Intel Xeon microprocessors, by generation. Intel Xeon E5-1620, top and bottom. P6-based
Emerald Rapids is the codename for Intel's fifth generation Xeon Scalable server processors based on the Intel 7 node. [3] [4] Emerald Rapids CPUs are designed for data centers; the roughly contemporary Raptor Lake is intended for desktop and mobile usage. [5] [6] Nevine Nassif is a chief engineer for this generation. [7]
