Intel Releases 14th Gen Core HX "Raptor Lake Refresh" Mobile Processors
Intel today announced the release of its 14th Gen Core HX series "Raptor Lake Refresh" mobile processors. Processor models from this series are supposed to cap off the upper end of Intel's mobile processor portfolio. Although Intel released the Core Ultra "Meteor Lake" mobile processors late last year, those chips cover the U-segment, and H-segment (ultraportable, thin-and-light, and mainstream); with the fastest model being the Core Ultra 165H, which caps out at 6P+8E+2LP. The HX segment, which started out as enthusiast-class, broadened in scope over the years to cover the bulky gaming notebooks and portable workstations. These chips typically have a power rating of 55 W. All chips have maximum turbo power rating of 157 W. Intel is tapping into its "Raptor Lake Refresh" silicon to carve out these processors. This is a monolithic chip built on the Intel 7 process, and its package is a multi-chip module with an on-package PCH.
The lineup begins with the Core i9-14900HX, which maxes out the "Raptor Lake Refresh" silicon, with an 8P+16E core-count, with 2 MB of L2 cache per P-core, 4 MB of L2 cache per E-core cluster, and a shared 36 MB L3 cache. The processor's full I/O is wired out, including support for dual-channel DDR5 (SO-DIMMs only), a PCI-Express 5.0 x16 connection for discrete GPUs, a PCI-Express 4.0 x4 connection for a CPU-attached M.2 NVMe SSD, and DMI 4.0 x8 link between the processor die and the PCH die. This PCH puts out up to 16 PCIe Gen 4 lanes, besides up to 12 Gen 3 lanes, which notebook designers can combine with discrete Thunderbolt 4 controllers, and the likes. You can expect Wi-Fi 7 to be prevalent in this crop of premium gaming notebooks. The i9-14900HX features a P-core maximum boost frequency of 5.80 GHz, and an E-core boost frequency of 4.10 GHz.
