Intel 14th Gen Meteor Lake CPU Spotted: 16 Cores and 42MB of Cache on 4nm Node [Report]

Intel’s 14th Gen Meteor Lake-P processors have been spotted in the Sisoft CPU database. We’re looking at two chips, a 16-core, and a 12-core part. The former is likely a Core i7 part or, as per Intel’s new naming scheme, a Core Ultra 7. It will feature 6 Redwood Cove “P” cores, 8 Crestmont “E” cores, and 2 Crestmont “LP” cores on the SoC die.

The Redwood Cove “P” cores will come with 2MB of L2 cache (per core), while the Crestmont “E” cores will share two 3MB chunks of L2 cache. The L3 cache will be 24MB wide and shared between all 16 cores. The two E-cores (LP) on the SoC die will likely have access to a smaller, slower cache block, resulting in reduced performance.

The other chip is likely the Core i5 or Core Ultra 5, with 4 Redwood Cove “P” cores, 8 Crestmont “E” cores, and 2 Crestmont “LP” cores. The four P cores will come with 2MB of L2 cache each for 8MB, while the E-cores will share two 3MB L2 cache chunks. Once again, the two E-cores (LP) on the SoC die will suffer from a slower cache reserve.

One of the primary changes with Meteor Lake includes an advanced process node (Intel 4), a chiplet design, and two E-cores on the SoC die. Using an advanced process node will improve the efficiency of these chips but raise per-die production costs. This will be offset using a chiplet architecture with 7nm/6nm dies fabbed by TSMC.

The use of a chiplet or tiled design will not only reduce production costs but also reduce the strain on Intel’s internal foundries, allowing them to focus on future process technologies. Including two Crestmont cores on the SoC die can be seen as part of a mobile-first approach. This allows the operating system to completely switch off the power-intensive compute die, leaving just the SoC and iGPU die enabled in light-threaded workloads.

Intel plans to launch the 14th Gen Meteor Lake CPUs in the year’s second half, likely fall. We should first see the mobility lineup alongside a Raptor Lake-S Refresh that may be labeled the first 14th Gen desktop family. The true 14th Gen desktop offerings should land next year in the form of Arrow Lake-S.
