Succession

Raptor Lake (RPL) is Intel's successor to Alder Lake, an enhanced Intel 7-process based microarchitecture for mainstream workstations, desktops, and mobile devices. The microarchitecture was developed by Intel's R&D center (IDC) in Haifa, Israel.

For desktop and mobile, Alder Lake is branded as 13th Generation Intel Core i3, Core i5, Core i7, and Core i9 processors.

Process Technology

Raptor Lake is fabricated on an enhanced version of the Intel 7 process. Internally it’s sometimes referred to as "Intel 7 Ultra", the company's 3rd generation SuperFin Transistor architecture. The enhanced node shifts the V-F curve enough to allow a significant reduction in voltage at ISO-frequency or, alternatively, a few 100 MHz improvement in frequency at ISO-voltage.

History

Intel teased Raptor Lake for the first time during their Investor Meeting in early 2022. At the Intel Innovation 2022 conference, the company officially announced Raptor Lake. Enthusiasts desktop processors started shipping on October 20. Mobile and the rest of the Raptor Lake lineup is expected to be announced at CES 2023.

Overview

Raptor Lake is an enhanced refresh of Alder Lake, a single-ISA heterogeneous multi-core microarchitecture. This SoC targets all client market segments from ultra-mobile devices to desktops and workstations. As with Alder Lake, Raptor Lake integrate two vastly different types of cores - up to eight big performance cores ("P-Cores") along with up to sixteen small efficiency cores ("E-Cores") onto a single monolithic integrated circuit. The big cores are designed to push single-thread performance while the small cores are designed to push multi-thread power efficiency. By finely orchestrating thread scheduling based on performance demand, Raptor Lake is designed to provide both higher multi-threading performance efficiency and better single-thread performance.

The Raptor Lake SoC integrate up to eight Raptor Cove big cores. Those cores are an enhanced version of the Golden Cove cores found in Alder Lake. Additionally, Raptor Lake also doubled the number of Gracemont cores to 16 cores comprising 4 quad-core clusters.
