Raptor Lake

Raptor Lake is Intel's codename for the 13th-generation of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficient cores. Raptor Lake launched on October 20, 2022. Mobile versions are expected to be released by the end of the year. 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 efficient cores) and 32 threads and is socket compatible with Alder Lake systems ( LGA 1700).

The company spokesman revealed that Raptor Lake was conjured in the last-minute, to benefit from all the process improvements before Meteor Lake arrives since the next microarchitecture was not ready on time.

Raptor Lake competes with the AMD Ryzen 7000 series that was launched about one month earlier on September 27, 2022.

Products

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 a Raptor Lake SKU, presumably called 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.
* All the CPUs support up to 128 GB of DDR4-3200 or DDR5-5600 RAM in dual-channel mode.
* All the CPUs support 16x PCI Express Gen 5 and 4x PCI Express Gen 5/4 lanes, but support may vary depending on motherboard and chipsets.
* Some models feature integrated UHD Graphics 770 GPU with 32 EUs and base frequency of 300 MHz.
* By default Raptor Lake CPUs are configured to run at Turbo Power at all times and Base Power is only guaranteed when P-Cores/E-cores do ''not'' exceed the base clock rate.
* 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.
