A patent filed by Intel<\/strong><\/a> has revealed more details about the Level 4 (L4) cache on its upcoming 14th-generation processors.<\/p>\n

VideoCardz<\/strong><\/a> recently spotted the patent on the United States Patent and Trademark Office website, in which Intel refers to the cache under the codename “Adamantine”.<\/p>\n

Adamantine is an adjective describing something unbreakable. Its name comes from a fabled metal in Greek mythology with the same name.<\/p>\n

The fictional metal alloy Adamantium, used to augment Marvel superhero Wolverine’s skeleton and retractable claws, was also derived from the term.<\/p>\n

The patent reveals that at least some of Intel’s 14th-generation processors \u2014 also referred to as the “Meteor Lake” generation \u2014 will boast on-package caches.<\/p>\n

The hybrid architecture of Meteor Lake will consist of five tiles \u2014 CPU, SoC, GPU, I\/O and base.<\/p>\n

The on-package caches will form part of the chip’s base tile, allowing for fast access by any system-on-chip (SoC) building blocks.<\/p>\n

The patent said the Adamantine cache would offer substantially faster access time between various parts of the chip than Level 3 (L3) cache, which usually forms part of the CPU tile.<\/p>\n

While the L4 cache looks like Intel’s answer to AMD’s 3D V-Cache, it also promises improvements over and above a general performance boost \u2014 such as boot optimisation and increased security for the host CPU.<\/p>\n

Intel previously used L4 cache on the eDRAM for processors from Haswell (2013) through Coffee Lake (2017).<\/p>\n

However, as Tom’s Hardware explained<\/strong><\/a>, that implementation proved too slow to offer real performance benefits.<\/p>\n

Lower-level caches are larger, increasing the likelihood of a cache hit. For this to improve, the physical placement of the L4 cache will be a critical factor.<\/p>\n

Intel’s Meteor Lake processors are expected to launch in the second half of 2023.<\/p>\n

It is currently expected to be limited to mobile devices \u2014 like Ice Lake and Tiger Lake \u2014 although some reports suggest the company could also refresh its Raptor Lake desktop line-up.<\/p>\n
