Rumor: Massive Cache Size Increase for Intel Raptor Lake Processors

Rumor: Massive Cache Size Increase for Intel Raptor Lake Processors

 Intel's Raptor Lake-S desktop processor would contain up to 68 MB of "total cache" (L2 and L3 cache). In consonance with what AMD is doing with the pending Ryzen 7 5800X3D and 3D Vertical Cache technology.

The concept was posted on Twitter by PC enthusiast OneRaichu and illustrated by Olrak29. The "Raptor Lake-S" silicon is projected to comprise eight "Raptor Cove" P-core clusters and four "Gracemont" E-core clusters (each cluster amounts to four cores). Compared to the 1.25 MB dedicated L2 cache found in the "Golden Cove" P-core found in "Alder Lake-S," the "Raptor Cove" core is supposed to feature a dedicated L2 cache of 2 MB in "Raptor Cove." A "Gracemont" E-core cluster contains four CPU cores that share an L2 cache. With the introduction of "Alder Lake," Intel expects to quadruple the size of the L2 cache for E-core clusters from 2 MB per cluster to 4 MB per cluster. Compared to "Alder Lake-S" (C0 silicon), the shared L3 cache on "Raptor Lake-S" (C1 silicon) has increased from 30 megabytes to 36 megabytes. As a result, the total size of the L2 and L3 caches is 68 MB. Everybody's attention is now focused on "Zen 4," and whether or not AMD would expand the size of L2 caches from the 512 KB per-core size that AMD has maintained consistently since the first "Zen."

No. Unlike us, the people designing these are not idiots.

We have already been over this extensively... it's a chip design meant for mobile platforms, forced on desktop... it is not preferable for a gaming desktop pc in any possible way.
