Rumour has it that Intel's 12th Generation Alder Lake-S processors are due to launch before the end of 2021, retiring the company's 11th Generation Rocket Lake processors with a shorter-than-normal shelf life. 

New leaks regarding Alder Lake have surfaced, with Videocardz gaining access to slides detailing the CPU core architectures behind Alder Lake and Intel's 600-series motherboard platforms.  

A critical aspect of Alder Lake is Intel's Golden Cove CPU cores and Alder Lake's use of Intel's "Enhanced 10nm SuperFin" process tech, which promises to grant Intel's lastest cores higher performance levels and heightened levels of power efficiency. Intel promises a 20% increase in single-threaded performance with Alder Lake in their leaked slide, though it is unclear what processors Alder Lake is being compared to. Is this a Tiger Lake or Rocket Lake comparison?

Alder Lake will be a hybrid CPU design, featuring high-performance Golden Cove CPU cores and high-efficiency Gracemont cores. This design is said to deliver Intel an "up to 2x" boost in multi-threaded performance, thanks to "Hardware-Guided Scheduling" and the addition of Gracemont CPU cores. 

Intel's leaked slides also state that Alder Lake will support PCIe 4.0 and PCIe 5.0 connectivity and DDR5, DDR5, LPDDR5 and LPDDR4 memory.

Based on the block diagram below, Intel's Alder Lake processors will support PCIe 5.0 connectivity across sixteen PCIe lanes and PCIe 4.0 connectivity across four PCIe lanes and their 8-link-wide DMI. This means that Alder Lake desktop motherboards will likely support PCIe 5.0 on their top x16 PCIe lanes and are unlikely to support PCIe 5.0 compatible M.2 slots. 

With support for both DDR5 and DDR4 memory, Intel's Alder Lake processors will allow consumers and system integrators to utilise their preferred memory, with DDR4 offering increased affordability and availability. In contrast, DDR5 offers increased power efficiency and more raw bandwidth. Whether DDR5 memory kits will outperform newer DDR4 memory kits when it comes to memory latency and gaming performance remains to be seen. 

Intel's Alder Lake CPU platform is also reportedly using a new CPU socket design and CPU heatsink mounting system, requiring Intel users to purchase new motherboards and CPU coolers (or cooler mounting kit upgrades) for Alder Lake. Intel's new Alder Lake socket is reportedly called LGA 1700, and it will replace LGA 1200.
