Raptor Lake
Raptor Lake is Intel's codename for the 13th- and 14th-generation of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficiency cores. Raptor Lake launched on October 20, 2022. Like Alder Lake, Raptor Lake is fabricated using Intel's Intel 7 process. At Intel's Investor Meeting 2022, it was confirmed that Raptor Lake would feature up to 24 cores (8 performance cores plus 16 efficiency cores) and 32 threads and is socket compatible with Alder Lake systems (LGA 1700). The company spokesman revealed that Raptor Lake was created to benefit from process improvements before Meteor Lake arrives since the next microarchitecture was likely to be delayed. On January 3, 2023 at CES 2023, Intel announced new desktop Raptor Lake CPUs and mobile CPUs. Raptor Lake competes with the AMD Ryzen 7000 series that was launched about one month earlier on September 27, 2022. The 14th-generation Raptor Lake-Refresh is the last processor family to use the old Core i branding scheme. Features

Desktop processors

Raptor Lake-S 
On September 27, 2022 at their Innovation event, Intel officially revealed six unlocked Raptor Lake SKUs launching for desktop on October 20, 2022. At the event, Intel CEO Pat Gelsinger confirmed that the then-upcoming highest-end Raptor Lake SKU, the 13900KS, could hit up to 6.0 GHz at stock configuration and would debut in 2023. Common features of Raptor Lake desktop CPUs:
 Socket: LGA 1700. RAM support:
 All models support up to 128 GB of RAM and up to 192 GB of DDR5 RAM after a BIOS upgrade. All models support DDR4 and DDR5 in dual-channel mode, up to 4 DIMMs total. All models support up to DDR4-3200 or DDR5-4800. The i5-13600 (K/KF/T) and all models above it support DDR5 speeds up to 5600 MT/s with max 2 DIMMS slotted, 4400 MT/s if 4 DIMMS are slotted. All CPUs provide 28 PCI Express lanes:
 16 PCIe 5.0 lanes
 4 PCIe 4.0 lanes
 8 DMI lanes
 Models without the F suffix feature either of the following integrated UHD Graphics GPUs, all with base frequency of 300 MHz:
 UHD Graphics 770 with 32 EUs, or
 UHD Graphics 730 with 24 EUs
 Max Turbo Power: the maximum sustained (> 1 s) power dissipation of the processor as limited by current and/or temperature controls. Instantaneous power may exceed Maximum Turbo Power for short durations (≤ 10 ms). Maximum Turbo Power is configurable by system vendor and can be system specific. CPUs in bold below feature ECC memory support only when paired with a motherboard based on the W680 chipset. Other SKUs do not support ECC memory at all. Mobile processors 
All mobile processors support the following types of memory: DDR5-5200, DDR4-3200, LPDDR5x-6400, LPDDR4x-4267. Raptor Lake-HX
