Intel “Alder Lake”/12th Generation Mobile H-Series CPUs

The 12th Gen Intel Core processor family will include 60 processors, set to power more than 500 designs across all PC product segments – from desktop gaming to ultra-thin-and-light laptops. 12th Gen Intel Core processors are the first based on Intel 7 process technology and the new performance hybrid architecture to enable major performance gains across a wide range of PC workloads.

At Intel Innovation, Intel unveiled the 12th Gen Intel Core processor family with the launch of the unlocked “K” desktop processors, including the world’s best gaming processor, the 12th Gen Intel Core i9-12900K. With a max turbo boost of up to 5.2 GHz and as many as 16 cores and 24 threads, the unlocked desktop processors reach new heights of performance for enthusiast gamers and professional creators. [1]

Figure 1 shows Intel has also advanced the technology of processors by introducing its new Performance Hybrid architecture, grouping cores into two new categories: P-cores and E-cores. Instead of using multiple cores that are largely identical, the new Intel chips use two kinds, the performance-focused P-cores and the efficiency-focused [2] E-cores. (This is something encountered recently when we compared old and new Intel desktop processors in our Intel Core i9-12900K vs. Core i9-11900K CPU face off.)

Intel's 12th-Gen Alder Lake at a Glance

  • Alder Lake is available now
  • Six flagship models: $589 Core i9-12900K, $409 i7-12700K, $289 i5-12600K. All three are also available as graphics-less KF models. Intel also has a range of 22 lower-priced models for desktop PCs.
  • LGA1700 socket requires new motherboards
  • The Alder Lake SoC will span from desktop PCs to ultramobile devices with TDP ratings from 9W to 125W, all built on the Intel 7 process. The desktop PC comes with up to eight Performance (P) cores and eight Efficient (E) cores for a total of 16 cores and 24 threads and up to 30 MB of L3 cache for a single chip.
  • Alder Lake supports either DDR4 or DDR5 (LP4x/LP5, too). Desktop PC supports x16 PCIe Gen 5 and x4 PCIe Gen 4, while mobile supports x12 PCIe Gen 4 and x16 PCIe Gen 3, Thunderbolt 4, and Wi-Fi 6E.
  • Intel's new hyper-threaded Performance (P) core, which comes with the Golden Cove microarchitecture designed for low-latency single-threaded performance, comes with an average of 19% more IPC than the Cypress [3] Cove architecture in Rocket Lake. It also supports AVX-512 and AMX (a new AI-focused matrix-multiply ISA) for data center variants (both are disabled on consumer chips).
