Introduction to Intel’s 14th Gen Core ‘E’ Embedded Processors
Intel has recently introduced a line of 14th Gen Core ‘Raptor Lake Refresh’ socket LGA1700 processors aimed at the embedded systems market. A standout feature of these processors is the disabling of the ‘Gracemont’ E-core clusters, making them pure P-core chips. Unlike previous iterations, these new chips are not built in the non-socketed BGA packages carried over from Intel’s mobile platforms.
Processor Specifications and Performance Segments
Intel’s latest processors address a broad range of performance market segments, including high-end applications. Leading the pack is the Core i9-14901KE processor, an 8-core/16-thread chip that boasts eight ‘Raptor Cove’ cores sharing a substantial 36 MB L3 cache. This processor achieves a maximum boost frequency of 5.80 GHz, with a base frequency of 3.80 GHz and a base power of 125 W. Additionally, the ‘K’ in KE denotes its support for overclocking. Its sibling, the Core i9-14901E, is a 65 W variant that lacks an unlocked multiplier and reaches a maximum boost frequency of 5.60 GHz, with a base frequency of 2.80 GHz.
Mid-Range and Entry-Level Options
The Core i7-14701E also follows the 8-core/16-thread pure P-core configuration, but with slightly lower frequencies—boosting up to 5.40 GHz and a base frequency of 2.60 GHz. For mid-range applications, the Core i5-14501E offers a 6-core/12-thread architecture based on the ‘Raptor Lake-S’ die, sharing 24 MB of L3 cache. This chip reaches a maximum boost frequency of 5.20 GHz and a base frequency of 3.30 GHz. Its variant, the Core i5-14501TE, has a processor base power of 45 W and slightly lower frequencies.
Entry-Level Variants and I/O Features
For more budget-conscious applications, Intel offers the Core i5-14401E, i5-14401EF, and i5-14401TE. The i5-14401EF lacks integrated graphics, while the i5-14401E/EF are 65 W chips with a maximum boost frequency of 4.70 GHz and a base frequency of 2.50 GHz. The i5-14401TE is a 45 W variant with a maximum boost of 4.50 GHz and a 2.00 GHz base frequency. All chips in the 14th Gen Core E-series feature the same I/O as the regular 14th Gen Core desktop processors, including a PCI-Express 5.0 x16 PEG interface, a CPU-attached Gen 4 x4 NVMe interface, and a DMI 4.0 x8 chipset bus, with support for dual-channel DDR4 and DDR5 memory types.
