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

Hardware Times

Intel's 14th generation Meteor Lake-P processors have been spotted in Sisoft's CPU database. These are two chips, one with 16 cores and the other with 12 cores. The first is likely a Core i7 or, according to 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 chip. of the SoC.

The Redwood Cove “P” cores will be equipped 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 24 MB wide and will be shared between the 16 cores. The SoC's two E (LP) cores will likely have access to a smaller, slower cache block, reducing 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 have 2 MB of L2 cache each for a total of 8 MB, while the E cores will share two 3 MB L2 cache blocks. Once again, the two E (LP) cores of the SoC will suffer from a slower cache pool.

One of the main changes brought by Meteor Lake is the use of an advanced processing node (Intel 4), a chiplet design and two E-cores on the SoC chip. Using an advanced processing node will improve the efficiency of these chips but increase production costs per chip. This increase will be offset by the use of a chiplet architecture with 7nm/6nm chips manufactured by TSMC.

Using a chiplet or tiled architecture will not only reduce production costs, but also reduce pressure on Intel's internal foundries, allowing them to focus on future technology. treatment. The inclusion of two Crestmont cores on the SoC chip can be seen as part of a “mobile-first” approach. This allows the operating system to completely turn off the power-hungry compute processor, leaving only the SoC and iGPU enabled in light workloads.

Intel plans to release the 14th generation Meteor Lake processors in the second half of the year, likely in the fall. We should first see the mobility lineup alongside a Raptor Lake-S Refresh which could be labeled as the first 14th generation desktop family. The true 14th generation desktop offerings are expected to arrive next year in the form of Arrow Lake-S.
