AMX was introduced by Intel in June 2020 and first supported by Intel with the Sapphire Rapids microarchitecture for Xeon servers, released in January 2023. [3] [4] It introduced 2-dimensional registers called tiles upon which accelerators can perform operations. It is intended as an extensible architecture; the first accelerator implemented is ...
Sapphire Rapids is a codename for Intel's server (fourth generation Xeon Scalable) and workstation (Xeon W-2400/2500 and Xeon W-3400/3500) processors based on the Golden Cove microarchitecture and produced using Intel 7.
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]
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.
Similar to Skylake, Golden Cove was described by Intel as a major update to the core microarchitecture, with Intel stating that it would "allow performance for the next decade of compute". Intel also described Golden Cove as the largest microarchitectural upgrade to the Core family in a decade, touting a 19% increase in instructions per cycle ...
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]
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 ...
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.
