Intel 14th Gen Meteor Lake CPUs Could Embrace An L4 Cache

Posted on

It is no secret that Intel is getting ready its 14th Technology Meteor Lake to rival the greatest CPUs. The chipmaker has already shared some characteristic units for the upcoming Foveros-packaged chips. Nevertheless, a brand new Linux patch implies that Meteor Lake will sport an L4 cache, which is occasionally used on processors.

The outline from the Linux patch reads: “On MTL, GT can not allocate on LLC – solely the CPU can. This, together with addition of assist for ADM/L4 cache calls a MOCS/PAT desk replace.”

The patch did not specify what “ADM” stands for. It might simply be a flowery advertising title for the L4 cache. The code did not expose the scale of the ADM, both. Traditionally, Intel has used 64MB or 128MB for the eDRAM for Haswell by Espresso Lake. Throughout its Scorching Chips 34 presentation, Intel shared the schematics of the Meteor Lake chip, which contains 4 completely different tiles: CPU tile, SoC tile, IO extender tile, and graphics tile. The quartet sits atop a big base tile that acts as an interposer.

Intel’s first implementation of the eDRAM (embedded DRAM) was with Haswell and served as an L4 cache for the CPU and iGPU. The chipmaker would proceed this follow till Espresso Lake. Nevertheless, just a few chosen desktop and cellular chips leveraged eDRAM over its brief utilization span. Broadwell was essentially the most distinguished structure to characteristic eDRAM. Chipmakers sometimes shun the L4 cache from their designs as a result of it is slower.
