Intel Next-gen Arrow Lake-S CPU Will Feature 3MB Cache For Performance Cores

As per Golden Pig Upgrade, the upcoming release in the Intel consumer series will include a boost in L2 cache for its Performance cores.

In the upcoming year, Intel is set to unveil Arrow Lake, a fresh architecture. This is expected to bring substantial enhancements over Raptor Lake, including novel CPU and GPU architectures, a reduced node size, and compatibility with the new LGA-1851 platform. Continuing the hybrid design pattern that merges Core (Big) and Atom (Small) cores, Arrow Lake will also introduce new microarchitectures called Lion Cove and Skymont. Particularly noteworthy is Lion Cove, which is projected to introduce a larger L2 cache.

The shift from Raptor Cove to Redwood Cove is anticipated to commence with the forthcoming Meteor Lake Core Ultra processors designed for mobile platforms. Over time, this transition will also encompass desktop systems, incorporating the Lion Cove cores similar to those in the Arrow Lake architecture. Leaked details indicate that the Arrow Lake architecture will provide a substantial increase in cache, featuring an additional 1MB to 3MB per P-core compared to the Raptor series.

With these improvements, the forthcoming generation is set to exhibit a 50% cache increase per P-core compared to the 13th Gen Core and a remarkable 140% surge when contrasted with the 12th Gen series. It’s worth mentioning that the specific dimensions of the E-core cluster cache, L3 cache, and L4 cache are yet to be officially verified. Meteor Lake is also projected to incorporate a similar cache configuration, which could potentially result in a significant cache enhancement for the series.

Observing the progression of Intel’s microarchitectures, there seems to be a substantial sixfold growth in cache size spanning four generations. This is especially remarkable given that the Cypress Cove architecture initially had just a modest 0.5MB L2 cache.
